Question about the Neurokinin 1 Receptor Antibody (NB300-101):why were the NK-1R in WB reported with different molecular mass(46kd, 50kd or about 70kd?)in publication 1,2 and 3? which is right?

Name: NK1R Antibody
Brand: Novus Biologicals
SKU: NB300-101
Rating: 4 (2 reviews)

Question

Accepted Answer

The theoretical MW of this protein is about 46KDa. Please see this reference for P25103 (https://www.uniprot.org/uniprotkb/P25103/entry). This is a protein database. The above MW weight is only theoretical and it can be expected that the MW differs between each experiment. The researcher who experienced this protein to be at 70KDa may not have reduced their protein enough which could have led to a protein complex, resulting in a larger MW.
