2.5. Bovine Serum Albumin (BSA) binding Studies: BSA solution was prepared in 5 mM Tris-HCl/10 mM NaCl buffer solution to keep pH value constant (pH=7.4) and it is stored at 4oC, used within 2h. The BSA concentration was estimated spectrophotometrically (ε280=44,300 M-1cm-1) [35], 60 µM BSA was titrated with increasing concentrations of Ru (II) complex (0-50 µM). Absorbance changes at 280 nm were monitored by UV-spectrometry. 2.6. DNA Binding Studies: Binding studies of DNA were carried out at room
ACIDITY TEST INTRODUCTION: Acidity is the total amount of hydrogen ion present in the food sample with the expectation of those bound to alkaline ions. The hydrogen ion can be either attached to acids or in the form of free ions or anions. Titratable acidity is different than total acidity although at times both terms are used to mean the same thing total acidity is the total amount of organic acids in the food sample. This all acids (tartaric, oxalic acid, citric acid, sulfuric acid, lactic acid
The purpose of this experiment was to determine the concentration of Bovine Serum Albumin protein through the use of the Lowry Assay. This was completed by first creating a standard curve from known concentrations of the Bovine Serum Albumin protein. First, it was essential to create ‘blank’ using water, and to measure the absorbance of the blank through the spectrophotometer. We were able to create several standards with known concentrations of BSA that included both low and high concentrations
paths of Iditarod. In the book, The Great Serum Race, by Debbie S. Miller, I learned that, in 1925, there was a race to get a serum for diphtheria to Nome, Alaska from Anchorage, Alaska. The doctors needed to get the serum to Nome before the disease spread. They needed a way to get the serum to Nome but they couldn’t use planes because they were only used in the summer so instead, they used sled dogs. When they had got the serum to Nome they lost the serum in the snow. When a musher called Gunnar
Naturalism, it isn’t really a word that we hear that often in our day to day lives, but what does it mean and how does it correlate to The Call of the Wild? Naturalism, in this regard, refers to the natural properties and causes which everything arises from. And in this context, we will be examining the setting, plot, and narrator’s storytelling within The Call of the Wild, and how these elements impact our understanding of this work and its relation to naturalism. The first item we will be looking
“The Iditarod race is a commemoration, or an event to remember something, of that historic event.”(Scholastic News) The “historic event” previously stated in the quote was about the delivery of diphtheria antitoxin to Nome, Alaska in 1925 when an epidemic struck everyone in Nome. This event created the challenging and fun Iditarod race from Anchorage to Nome. The racers ride on a sled pulled by dogs who they bond with and learn to care for. Although the original race to bring the medicine to Alaska
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
1.1 Boron History & Overview: Boron is an element of the periodic table belonging to the group 13. It is the only non metal present in its group. Boron has three valence electrons. It is capable of forming covalent bonds between atoms of similar nature to form polyhedral clusters. Boron has 2 stable isotopes in nature. i.e.11B (80.1%) and 10B (19.9%). Boron exists in bound state. Figure1. Elemental form of boron The history of boron is derived from almost 6000 years ago, when boron compounds
electrophoresis is used to separate the proteins which can be observed as thick and thin bands on the electrophoresis gel. In this experiment we use SDS-free polyacrylamide gel. Sample proteins used in this case are bovine serum, human serum, goat serum, chicken serum and horse serum. Since the SDS is negatively charged, sample proteins move to the positively charged anode through the gel. Small proteins migrate faster since it is light and is seen further below the gel than the larger proteins which
2013) but there is no evidence that it can also be a potent inhibitor of diverse class of standard proteins. So, we will check the effect of this compound on the aggregation behavior of standard proteins such as Bovine Serum Albumin, Human Serum Albumin and other mammalian serum albumins proteins. Till now we know that these standard proteins and some amyloidogenic proteins such as amyloid beta peptide, tau protein, IAPP, TRR protein are responsible for the diverse diseases which are caused by the aggregation
min. Measure the absorbance of the standard (Abs.S), and Test Sample (Abs.T) against the Blank, within 30 min. Calculations Uric Acid in mg/dl = Abs.T X 8 Abs.S 2. MICROALBUMINURIA Albumin refers generally to any protein that is water soluble, which is moderately soluble in concentrated salt solutions, and experiences heat coagulation (protein denaturation). They are unique
be excreted by the body because it doesn’t filter into the glomerular tubule and this is mainly because of its large size. In this lab the experimental value for binding of acetaminophen to serum albumin was calculated to be 21.93%. The binding of different drugs differ greatly in their ability to bind to serum proteins. One major problem in performing this experiment was that the plasma was contaminated with mint wax-dental floss that was used to tie the ends of the dialysis tube. This affected the
determination of total protein in serum is based on the biuret reaction. The serum protein reacts with copper sulphate in the presence of sodium hydroxide. The Rochelle salt (K-Na-tartarate) contained in the biuret reagent is utilized to keep the formed cupric hydroxide in solution which gives the blue colour. The absorbencies of the sample (A sample) and of the standard (A standard) were read against the reagent blank in the spectrophotometer at a wavelength of 545nm. The total serum protein concentration
INTRODUCTION: Acalculous cholecystitis(AAC) is an acute necroinflammatory disease of the gallbladder with a multifactorial pathogenesis. It accounts for approximately 10 percent of all cases of acute cholecystitis and is associated with high morbidity and mortality rates (1) Most cases of acute acalculous cholecystitis occur in the setting of prolonged fasting, immobility and hemodynamic instability (2), however autoimmune diseases like systemic lupus erythromatosus (SLE) has also been proposed
syndrome results from increased serum viscosity due to high protein content in multiple myeloma. Clinical pearls: • Multiple Myeloma is a plasma cell malignancy that causes end organ damage- CRAB Calcium elevated Renal failure Anemia Bone lesions • Median age of diagnosis is 70 years • Male > Female. Blacks are almost twice more commonly affected than whites • Suspect MM if high total protein : albumin ratio • MM is characterized
On PC final edit "new look" in human maternal-fetal nutrition Low birth weight serum albumin and incidence of neonatal jaundice Maternal nutrition is the most influential, nongenetic environmental factor for the growth of fetus during the course of pregnancy. Growth of the fetal tissue imposes metabolic alteration in mother’s body resulting in an increased demand for nutritional requirement. Though the human fetus synthesizes its own carbohydrates, fats and proteins form glucose, amino acids and
Research Question: What is the effect of heat on the activity rate of albumin protein? Introduction: Heat and pH are common factors that denature proteins and enzymes; in this case heat will be used to break down a specific protein known as albumin. Albumin is found commonly in egg whites, milk, and in blood serum but in this particular experiment egg whites will be used. When the albumin is denaturized its function and shape are changed, while there are instances where the protein can go back to

In order for humans to overcome increased demand for nutrients in an ICU setting it is important that nutrition be available readily. “Nutritional support is essential for critically ill patients in the intensive care unit. It provides energy, protein and other nutrients for patients who cannot be fed orally. According to the author, “Consideration in determining the type and amount of nutritional support depend on the patients underlying medical conditions, nutritional status and available route
