accessory NEF protein in HIV infection Kanokporn Tangthamvanich Department of Microbiology and Immunology University of Otago [Word count: 895] The role of the accessory NEF protein in HIV infection In human immunodeficiency virus (HIV) infection‚ there is one essential virulence protein‚ the Nef protein‚ which is identified as a negative factor due to it having a negative effect on viral replication (1). It performs critical functions in the host during the viral life cycle. The Nef protein is only

To purify the protein in the cell lysate from lab 1 through nickel affinity chromatography. Protein purification should result in only one type of protein ideally‚ which is the protein of interest‚ wt-DHFR and mut-DHFR in this case. A pure protein allows for further analysis on the protein to be conducted‚ such as its concentration (Bradford assay)‚ its molecular weight‚ and its biological activity. 2.

Protein Deficiency Symptoms Protein deficiency symptoms are the first signs that your diet may be lacking in complete proteins. When your body isn’t getting the nutrition it needs to function well‚ it gives you signals that something is wrong. Pay attention to these symptoms and seek medical advice if you experience them. Common Protein Deficiency Symptoms Even with a wide variety of protein sources available‚ some people experience protein deficiency symptoms due to a lack of protein intake

Topic: Protein Folding and Molecular Chaperones - What happens when proteins fold incorrectly? Consequences of Protein Misfolding Vina Ong 20554965 Section: 126 Ares Rao A protein is made of amino acids that supply cells with their formation and execute most of their activities. Proteins can easily be denatured and refolded which happens spontaneously as the denaturing solvent is added and removed‚ under the proper circumstances. (Alberts‚ 2014) Since they can be easily denatured there

Gel Electrophoresis Adventure Intro The final goal of this lab was to successfully measure the size of different samples of DNA by placing each sample into a well in agarose gel and running a current through a charged chamber. The DNA samples will move through the gel towards the positive charge. Ideally‚ the DNA will move and create and sequence of smallest to largest. This lab exposes us to DNA technology.
