1. What are the molecular weights of the different laminin isoforms?

The molecular weights (MWs) of the different laminins isoforms are stated in the table below. Due to the complex post-translational modifications such as glycosylation of the laminin molecules, the MWs of each laminin is deduced by amino acid sequences used as reference.

 

2. Which antibodies do you recommend for recognizing different laminin chains in tissue?

Antibodies against human laminin subunits (specificity and reactivity in Western Blotting):
