SDS-Polyacrylamide gels were prepared and the glass plates were washed with 70% ethanol and water. After drying the plates, water was used for test leakages. Two SDS-Polyacrylamide gels were prepared according to the following recipe. These all above components of the running gel were added in a 50 ml tube and solutions were mixed and pipetted into the prepared gel chambers. Glass plates were filled ¾ and the gel was covered with 100-500 µl Isopropanol in order to achieve an even surface. When the gel was polymerized, isopropanol was removed on the top of the running gel with water and thus, water was also removed as well. Then, stacking gel was prepared and its polymerization reaction was started with TEMED, and its solution was quickly poured on the top of the running gel. Therefore, a comb was inserted into the stacking gel before its polymerization, to form the loading wells. When the gel was polymerized, the inner chamber was filled with electrophoresis running buffer and the outer chamber was filled half.

The gel piece with the lanes 7-10 was put in a 10 ml blotting buffer until western blotting. The gel piece containing the lanes 1-6 was then placed under UV-light or onto a transilluminator for the visualization of the fluorescent modification. Then the visualized gel was documented by taking a picture in Gene map program. Afterwards, the visualized gel was stained with Coomassie Brilliant Blue protein stain. Staining was done for 30 to 60 mins, within this time the staining solution was recycled after 15 mins. Then destaining was done in a destaining solution and the solution was recycled several times until the background staining disappears and the used solution was collected in a bottle. Then its picture was
Introduction: Isopods are crustacean, which is split into smaller groups, called order. Scientifically Isopoda order is called isopods, which include pill bugs and sow bugs (Crustacean class). Most of the time isopods are mistaken for “bugs” since they look like insects.
Discussion PV92 Gel Electrophoresis Results: Through the usage of gel electrophoresis the correct allele for each sample was able to be determined. Lanes one through three in the gel,were the positive control lanes they contained the PCR cocktail and a known high-quality template for the PCR reaction. First lane contained the sample with the +/+ allele, which had two copies of the ALU repeat allele. The first lane had a band at about 941 base pairs.
There were solid pieces produced that were a dark reddish color. This change in color shows that there must have
To begin the process, a pre-prepared 1% agarose gel was obtained. The gel chamber was set up by placing the agarose gel into the chamber and submerging it in plentiful TAE buffer. The wells were filled with both PCR and DNA and shared between six students. The wells were labeled 1-7. The first well was pre-loaded with DNA ladder and labeled as 1 microliter kb DNA ladder.
Bacterial transformation is a technique widely practiced by scientists for research purposes. This experiment explored the transformation of E. coli cultures with pGLO plasmids to allow the bacterial cells to express a foreign protein and emit a fluorescent glow under UV light. The transformation was completed through the heat shock method. Both transformed and untransformed E. coli cultures were grown in four mediums. The four mediums were made of different combinations of the LB nutrient broth, ampicillin and arabinose C sugar.
The pigment containing chromatophores are encased in a sac that has six to twenty small muscles. When the muscles contract the sac of pigment is
The same region is also amplified on both chromosomes, however they are different sizes, which are then put into gel
The purpose of this experiment was to insert the plasmid glow green into the bacteria with a gene of interest to produce the protein that make the bacteria glow green along with the presence of arabinose and the presence of ampicillin. Many scientists are experimenting different kind of genes that can inserted into the organism for survival. The technique of transformation was used in this experiment to give the organism a new trait that they did not possess in their life. In this experiment, the bacteria were added to four plates with certain conditions such as the existence of plasmid, ampicillin, and arabinose to see whether the bacteria grow and glow green. The results showed that the LB/amp/araC +pGLO produce a lot of colony and most
They often have a golden or yellow colour and β–hemolysis on sheep blood agar (Wang, Braughton,
To exclude technical variations, the target and reference genes were assayed on the same card. The cycle relative threshold method (Crt method) was applied. The expression of target genes across the samples was calculated using the equation ΔCrt, in which [ΔCrt = target gene Crt – the mean of reference genes Crt]. A lower ΔCrt indicates higher gene
Research question What is the effect of temperature Amylase activity? Word count-1453 Background research Enzymes are biological catalysts that speed up a chemical reactions. They do this by decreasing the activation energy(the energy needed to start the reaction) of a chemical reaction. The enzyme present in our saliva is called Amylase. Amylase increases the rate of reaction by decreasing the activation energy needed to hydrolyse the starch molecules.
Next, I dye the Unknown with Gram’s iodine to create a complex only have on gram positive. The slide is rinsed by water after 30 seconds. Decolorization is the next step of the whole process. I let the alcohol flow on 45-degree angle slide within 15 seconds and wash it with water to remove colors on the surface. Lastly, the unknown is once again dyed with safranin for 1 minute then wash it off with water for the last time and dry it using bibulous paper.
Finally, the amplified DNA regions are compare using a gel. DNA Profiling
Successful treatment of acute high lethal dose of Acrylamide poisoning Acrylamide has cellular oxidative effects and is classified as 2A carcinogens in human being. Acute or chronic poisonings with this agent happens due to skin, respiratory or oral contacts. Clinical manifestations depend on dose, contact duration and frequency. Management of these patients consists of conservative and palliative therapies for reducing of oxidative effects.
Conclusion and Recommendations Ultimately, testing cell viability and knowing the count of viable and non-viable cells in a cell line is an important key in any research using cells. Having enough number of viable cells in a suspension would give accurate results in an experiment. This also shows how trypan blue is an important dye in cell viability and in the study of cells. This dye makes researcher’s life convenient in identifying and differentiating viable versus non-viable cells or live versus dead cells. It is really needed that researchers should ensure new and fresh cell cultures to ensure more viable cells in a culture.
