Abstract This experiment was performed to determine the contraction of different serum proteins in the body and to examine and detect abnormal proteins in the body. While completing this lab, it is important to have knowledge that serum proteins separated often and using the agarose gel can detect the migration of the proteins. During this process, the components (proteins) will move at different rates. The purpose of this experiment was to detect the concentration of the four proteins and examine the serum table list to see if the proteins migrated toward the positive electrode. We had four proteins that were dissolved in the sample buffer which are: Cow serum, Serum albumin, Transferrin, and Gamma globulins. These serum proteins were separated by using agarose gel electrophoresis. This allowed the proteins to separate and the proteins may carry a charge that would be negative or positive while on the gel. After separation, the gel displayed that Transferrin traveled further due to the charge. Introduction There are three different cellular components that blood contains (erythrocytes, leukocytes, and platelets). Blood is essential to our body since it assists living cells and reinforces the tissues in our body. It also contains the nutrients from the food that we intake and process. The serum is a …show more content…
We added 50ml of the buffer into the flask, and we boiled the solution for two minutes in the microwave. The sample well was taped with table and par film to keep the agarose gel from leaking. I loaded the 15ul of the five serum proteins: Cow serum, Serum albumin, Transferrin and Gamma globulins. The electrophoresed gel was placed on the voltage machine at 110 volts for 1.5hours. We removed the gel from the sample well and place the Coomassie Blue stain. The gel was detained with vinegar by the professor. The next class period, we observed the sample well
Introduction The purpose of this Lab was to identify the density of the unidentified object and determine what substance the unidentified object given by the teacher was. The density calculated in the experiment will stay the same because the density of the unidentified object will stay constant. The Independent Variable of this experiment was the calculated density and the unidentified object given. The Dependant Variable for this experiment was the density.
Although the overall absorbance increases as more milliliters of mitochondrial suspension is added to a mixture of 0.25 mL of 0.5 mM DCIP, 0.5 mL of 50 mM sodium azide, various volumes of assay buffer (20 mM potassium
When given an unknown bacteria there are a multitude of steps one must go through to be able to correctly identify what bacteria was given. It is important to correctly identify the bacteria because some bacteria are more harmful than others. The gram stain is the first test that should be performed because it helps narrow down the possibilities by telling one whether the bacteria is gram positive or gram negative. After this test is performed, one shall place bacteria on/in Mannitol Salt agar, MacConkey agar, Eosin Methylene Blue agar, Urea agar, Simmon’s Citrate, Purple Beef broth with Lactose and finally Purple Beef broth with Sucrose. A streak plate should also be made up, this helps one identify the morphology of the colonies.
An average adult body with a weight of 150 to 180 pounds will contain approximately 4.7 to 5.5 liters (1.2 to 1.5 gallons) of blood. An average child with a body weight of 80 pounds will have approximately half the amount of blood as an adult. Blood carries out many critical functions in the body. It transports nutrients and oxygen to the body's cells. It also takes away waste from those cells.
Blood reoccurs through the duration of the novel. In chapter 11... "Blood is the life" is stated (181). Blood is gives humans life, such as in chapter 12 when Lucy is on her death bed and in need of a blood transfusion: "One, two, three, all opened their veins for her..." (190). Dracula's desire for blood presents its importance. This also show his lust for a human's most important possesion, their blood.
1 “substrate” and another “ enzyme.” Instead of using the distilled water, this time you are going to use different pH buffer in the enzyme test tube. In the substrate tube, add 7 mL of distilled water, 0.3 mL of hydrogen peroxide, and 0.2 mL of guaiacol for a total volume of 7.5 mL. For the enzyme tube, instead of distilled water add the pH solution (3) and 1.5 mL of peroxidase which equals a total volume of 7.5 mL. Use the dH2O syringe for our pH solution. To clean the syringe, flush it by drawing 6 mL of distilled water.
Starch solution is then placed into the test tube at a quantity of 5 mL. 5 drops of Lugol’s Iodine solution is added to the test tube. If the color changes, then it is known that starches are present in the solution. Proteins are next tested. In order to do this, 5 mL of gelatin solution is added to the test tube. 10 drops of Biuret’s reagent are added to test for protein.
The investigation was carried out to identify the presence or absence of biological molecules in serum 2216. If the concentration in each test tube of the dilutions carried out will be more concentrated then the concentration of the test tube before it, then the color will be at an equal concentration with the other dilutions performed. The hypothesis was wrong because of the difference in concentrations due to the different measurements within the dilutions done. The test for starch was to add a drop of iodine solution to the pipette in the spotting tile. A reducing sugar solutions is add inside a test tube with 3 drops to then add 3 drops of benedicts and plane in a water bath.
Proteins were found in the victim’s stomach contents by exposing the contents to the Biuret solution and getting a positive result after the solution became purple. Protein can also be found in the meat of the victims typical, “…pizza with sausage, pepperoni, and bacon…”. Lastly, starches were found in the victim’s stomach contents though exposing the victim’s stomach contents to the Iodine solution and getting a positive result after the solution became a dark color. In pizza, starches can be found in the entire
Blood serves a vital role in the survival of humans. The importance of blood is seen during situations that demand the transfusion of blood or specific blood components. Surgeries, deliveries and emergency accidents are examples of situations that may demand blood transfusion or hemotherapy. An adequate supply of blood units is important in blood banks for them to be able to deliver its function.
Lab 3 – DNA extraction and visualization Journal -Madhu Thalari. 1.Describe the laboratory exercise as you interpreted it.? Ans: This lab has given me methods to extrct DNA from both plant cells and animal cells. The main steps that are followed in both methods made me understand the reasons behind them. In order to extract DNA we need break the barriers(cell wall and cellmembrane), remove water, protiens and other unwanted material, make sure that the chemical we used should not damage DNA that we need and add flouroscent material to visualize the DNA.
1.1 Abstract The purpose of quantitative analysis of protein using a spectrophotometer is to measure the concentration of proteins in a given sample. The experiment is conducted by laboratory method (Biuret Test) and using spectrophotometer to analyze the absorbance of reactants at 540 nm, hence determining the concentration of the proteins in a given sample. The purpose of stopped enzyme assay to study B-galactosidase is to determine the effect of temperature and concentrations of substrate on enzyme activity.
The blood is a body fluid that circulates constantly. It transports oxygen to the cells by the work of the red blood cells which contain haemoglobin. White blood cells attack, destroy and remove abnormal and old cells and also fight infectious agents and foreign substances. Platelets take part in blood clotting.
The reactions involving such kind of antigen and antibody interaction are known as agglutination reactions. This type of reaction occurs at the surface of erythrocytes, bacterial cells or animal cells at which the antigens are present [1].The results of these reactions are clearly observable since they form large sedimented particles in form of visible clumps. Formation of clumps is due to antigen and antibody complex formation. The ease of its performance and identifiable results make it viable for large clinical importance. Its most important clinical application involves the detection of bacterial infection.
It also better to ensure that the materials like hemocytometer and pipettes are sterilized and clean so that there would be lesser or no artifacts would be seen under the microscope. The researcher was to use trypan blue exclusion method to test for cell viability, observe the non-viable and viable cells, and was able to have a cell count using the
