Laminin, mouse purified
| Laminin, mouse purified |
| Overview |
Specificity:Molecular weight = 850 kD; 3 chains expressed as two major bands at 200 and 400 kD on SDS-PAGE.
Preparation: Prepared from Engelbreth-Holm-Swarm {EHS} sarcoma according to the method of Templ et al 1979 {http://www.jbc.org/cgi/reprint/254/19/9933.pdf}
Briefly, tumor homogenates were subjected to NaCl extractions and centrifugations. Laminin was found in the 0.5M NaCl fraction. After subsequent salt gradients and further centrifugation steps, the laminin was dialyzed against 2M urea and passed
over a column of DEAE, followed by molecular sieve chromatography and concentration by ultrafiltration. |
