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

Later in the trial polyacrylamide gel electrophoresis was utilized to separate BSA from hemoglobin. Methods I. Gel Filtration and Protein Assay: 1. A slurry of Bio-Gel P-100 beads in water was added to the column (diameter 1.0 cm‚ length 20 cm) until a height of 10-12 cm was reached. 2. The column was then equilibrated by allowing

Boy Scouts of America (BSA) Boy Scouts of America is one of the biggest youth organizations in the United States. The mission of the Boy Scouts of America is to prepare young people to make ethical and moral choices over their lifetimes by instilling in them the values of the Scout Oath and Scout Law. The Scout Oath reads‚ “On my honor I will do my best to do my duty to God and my country and to obey the Scout Law; to help other people at all times; to keep myself physically strong‚ mentally

Using the standard curve equation (y = 1.6147x + 0.0968) derived from determining the regression equation of different protein concentrations of BSA‚ an accurate form of protein concentrations were obtained for three different given samples‚ including an unknown. A notable empirical observation found in this experiment is the gradual increase in dark color change (i.e.‚ blue) as the concentration

Chapter 1 The Problem and its Background Introduction Study habit is defined as the regular tendencies and practices that one depicts during the process of gaining information through learning. In short‚ it is the way that you study. It includes time management or how much time you afford in studying‚ your desk‚ the lightings‚ what subject you start on studying‚ whether you study with or without music‚ do you take down notes or not‚ do you sit or lie down‚ etc. Despite the fast pacing growth
