Cell and Tissue Lysates
LSBio offers whole protein lysates from cells and tissues commonly used in research in a Ready-to-Go Western Blot format. More than 30 cell lysates are
available from A549, 293, 293T, U251, 3T3, and other cell types, as well as tissue extracts from various normal mouse organs like brain, liver, kidney, and more.
Each sample is supplied in an SDS loading buffer containing 0.3% beta-mercaptoethanol making them ideal for use as Western blot positive controls.
The recombinant S1 subunit of human SARS coronavirus (isolate:WH20) spike comprises 665 amino acids and has a predicted molecular mass of 74.4 kDa. The apparent molecular mass of the protein is approximately 85.8 kDa in SDS-PAGE under reducing conditions.
