P c) SDS page is done to detect presence of subunit or state of oligomerization of protein. SDS page , contains beta mercaptoethanol which reduces disulphide bonds present in protein.
Sample 1: Protein A in a sample buffer with B-Mercaptoethanol. Sample 2 Protein A in a...
SDS Page Gel: The provided standard protein sample for electrophoresis consists of 9 polypeptides with molecular weights ranging from 250 to 15 KDa. Sample 1: Protein A in a sample buffer with B-Mercaptoethanol Sample 2: Protein A in a sample buffer without B-Mercaptoethanol Sample 3: Protein B in a sample buffer with B-Mercaptoethanol Sample 4: Protein C in a sample buffer without B-Mercaptoethanol Use the picture below & the information about the proteins above to answer the following questions. 1a....
Sample problem: Protein structure Determine the subunit composition of a protein from the following information: • Molecular mass by Gel filtration: 200kD • Molecular mass by SDS PAGE: 100kD • Molecular mass by SDS PAGE with 2- mercaptoethanol: 40 kD and 60 kD.
Carl has just finished purifying a protein and analysis by gel filtration indicated that the molecular weight of the native (undenatured) protein was 130,000 dalton. His advisor wanted him to determine whether this protein had quaternary structure using gel electrophoresis. He wants to be able to describe the molecular weight of each of the subunits and the forces involved in linking these subunits together (disulfide linkages and/or electrostatic, hydrogen bonding and hydrophobic interactions). Carl first analyzed his pure protein sample...
Two different experiments were performed to determine the quaternary structure of HCV reverse transcriptase as well as the molecular size of each subunit. In these experiments, HCV reverse transcriptase was mixed with equal masses of two proteins with known molecular weights of 10 KDa and 80 KDa. Both of these proteins consisted of a single polypeptide chain. This mixture was then separated by gel filtration (below) or by SDS-PAGE (below). Gel Filtration Column: The absorption as a function of the...
A protein gives two bands of 50 and 80 kD on SDS PAGE. Treatment with 2-mercaptoethanol gives two bands of 50kD and 40kD. Give detailed information about this protein including its molecular weight.
A protein sample complex consists of two proteins, a smaller protein, X, and a larger protein, Y. Protein X is composed of two polypeptide chains linked by disulfide bonds. Protein Y is composed of three polypeptide chains linked by disulfide bonds. The complex is analyzed by native PAGE, reducing SDS-PAGE and non-reducing SDS-PAGE. Native PAGE does not include sodium dodecyl sulfate, or SDS. Reducing SDS-PAGE uses both SDS and a reducing agent in the buffer. Non-reducing SDS-PAGE uses SDS, but...

(3) The 2x sample buffer contains SDS and B-mercaptoethanol. What are their functions? (1 pt) (4) What samples would you load on the gel besides the purified plant protein? Explain your reasons for loading those samples. (2 pts) (Hint: In this lab you loaded Ladder, BEW, pool A, and pool B. Only pool B contains the purified protein, but why do we need to load all the other samples? Same principles should apply to this question for the plant protein.)...
