standard curve with the understanding that the results on the unknown protein are semi-quantitative. Since most proteins are not available in large quantities‚ standard curves for protein assays are typically based on the use of either bovine serum albumin (BSA) or bovine gamma globulin (IgG). The Bradford protein assay is a method to determine protein concentration in the mixture. This method is based on the proportional binding of the dye Coomassie to proteins. If there is a higher protein content

The Arrhenius plots of these and those for two mesophilic enzymes (glutamate dehydrogenase from bovine liver and ‚)-galactosidase from Escherichia coli)‚ exhibit no downward deflection corresponding to the glass transition‚ found by biophysical measurements of several non-enzymic mesophilic proteins at about -65 °C and reflecting a sharp decrease in

Dr. Frankenstein’s Journal Before arguing about a topic‚ it is generally a good idea to know what it is that is being argued. Genetic engineering is a relatively new technique‚ involving the transfer of genes from one organism to another. It is also described as the “modification of genetic material by man that would otherwise be subject to the forces of nature only” (Carlson‚ n.d.). Genetic engineering is a powerful and potentially very dangerous tool; it changes the physical properties of organisms

Among these proteins only whey proteins alpha-lactalbumin‚ beta-lactoglobulin‚ bovine serum albumin (BSA)‚ and lactoferrin‚ as well as the four caseins‚ have been identified as allergens. A study evaluated cow’s milk allergens

Thus‚ glucagon and insulin are part of a feedback system that keeps blood glucose levels at a stable level. Glucagon belongs to a family of several other related hormones. Somatostatin (also known as growth hormone-inhibiting hormone (GHIH) or somatotropin release-inhibiting factor (SRIF)) is a peptide hormone that regulates the endocrine system and affects neurotransmission and cell proliferation via interaction with G-protein-coupled somatostatin receptors and inhibition of the release of numerous

Draft: Introduction: Transgenesis is the process by which new characteristic(s) can be introduced into an organism that it did not have previously. Exogenous gene(S)– called transgene- are introduced into an animal through the use of recombinant DNA technology. The extra genes or gene may come from same species or from a completely different species. Transgenesis has many beneficial applications for human application such as producing milk with human proteins‚ which help with treatment of

Biochemistry‚ GRT1 Task 2 Essential Amino Acid Valine A1: 2 Characteristics of Valine • Valine is a nonpolar amino acid‚ with many carbons surrounded by hydrogen. Valine is unable to interact with water molecules‚ making it HYDROPHOBIC (MSDS‚ 2005). • Flammability- Valine is combustible at high temperatures. These products are carbon oxides and nitrogen oxides. In case of a small fire‚ dry chemical powder should be utilized. In case of a large fire‚ utilize water spray‚ fog or foam. No water

diarrhea Diarrhea is an increase in the frequency of bowel movements or a decrease in the form of stool (greater looseness of stool). Although changes in frequency of bowel movements and looseness of stools can vary independently of each other‚ changes often occur in both. Diarrhea needs to be distinguished from four other conditions. Although these conditions may accompany diarrhea‚ they often have different causes and different treatments than diarrhea. Diarrhea is the frequent passing of loose

Northfield Laboratories both generate their product by extracting hemoglobin from outdated human blood. Biopure generated their product by the purification of bovine blood. The consumer might have issues using a blood substitute that is generated via bovine blood as compared to human blood. Biopure would have to convince the market that the bovine blood is just as compatible and safe as the purified human blood substitute. Biopure might have issues in trying to persuade the public of this issue and
