When performing a Western blot, after running an SDS-PAGE gel, a transfer step is performed.The purpose of this transfer is to:Group of answer choicesAllow the proteins to be visualisedReduce the background ‘noise’ and reduce false positive resultsImmobilise proteins onto a nitrocellulose membraneSeparate the proteins based on their size and charge

In the context of Western blot, what is the role of the primary antibody?To visualize the proteins on the membraneTo denature the proteins in the sampleTo transfer proteins from gel to membraneTo bind specifically to the target protein

What is the purpose of the Western blot technique?To separate proteinsTo sequence DNA fragmentsTo amplify DNA sequencesTo detect specific proteins in a sample

A protein was run under native conditions in a gel filtration column and was calculated to be of 120 kDa in size. The molecular weight of the protein in SDS-PAGE was found to be 30 kDa. The oligomeric status of the protein is

Pre-lab Question, Session 2: Which of the following is a consequence of adding SDS to sample buffer and the SDS gel, adding beta-mercaptoethanol to the sample buffer, and boiling the sample before running our SDS-PAGE gel in lab?Group of answer choicesProteins can be separated based on sizeAll of these answers are correctProteins can be separated based on their 3D structureProteins can be separated based on their net charge

Which of the following property of a protein is exploited in gel filtration chromatography
