biochemical studies that takes advantage of a protein’s amphoteric nature to determine its molecular weight and charge by running the sample through a gel matrix under the influence of an electrically charged field. A popular example of gel electrophoresis is Sodium dodecyl sulfate-polyacrylamide electrophoresis or SDS- PAGE which has been used in this experiment to supposedly determine albumin and casein’s molecular weights respectively. The system used in gel electrophoresis consists of 3 major parts:

GM foods is difficult and the failure rate is high. This is why we (my partner and I) feel GM foods should be banned until scientist’s know ALL the affects Gm foods has on humans and the environment. Genetically modified foods use the latest molecular biology techniques and are commonly used for growing crops for human or animal consumption. GM foods can create specific characteristics of plants or animals‚ such as the ably to withstand weather conditions(temperature)‚ nutrition and they can keep

MATERIAL AND METHODS Recombinant protein production The recombinant T-Rp3 was expressed in E. coli BL21 (DE3) as previously described (Favaro et al.‚ 2014) and purified by a single step His-based affinity chromatography in an ÄKTA purifier FPLC (GE Healthcare). Protein was then dialyzed against 50 mM MES buffer (pH 6‚0) overnight at room temperature‚ frozen in liquid nitrogen and stored at -80 ˚C after 0.22 μm pore membrane filtration.

After all‚ a larger number of people demand a larger amount of food. Factory farming is a good way to sustain a large amount of people with food‚ and is a way to meet the demands of variety and cheapness that will become increasingly important with population growth‚ but unfortunately it is not sustainable.

Simple Diffusion 1. The following refer to Activity 1: Simulating Dialysis (Simple Diffusion). Which solute(s) were able to pass through the 20 MWCO membrane? According to your results‚ which solute had the highest molecular weight? ______________________________________ Which solute displayed the highest rate of diffusion through the 200 MWCO membrane? __________________________ Using the data from Chart 1‚ explain the relationship between the rate of diffusion and the size of the solute.

able to detect and analyze proteins based on their ability to bind to a specific antibody‚ the SDS-PAGE and Western Blot was performed. SDS Polyacrylamide Gel Electrophoresis (SDS-PAGE) is a very common technique used to separate proteins based on molecular weight under the influence of an applied electrical field and then used to prepare for the Western Blot (#1 Lehninger). The support medium used is a polyacrylamide gel and‚ it also used sodium
