Application

Promotes the adhesion and growth of human carcinoma and sarcoma cells, human retinoblastoma cells, liver cells, mouse neuroblastoma cells, mouse embryonal carcinoma cells, and seems to be involved in the development of embryonal tissue. The optimal laminin concentration may vary with the cell type and has to be determined experimentally.

General description

Product Source: Isolated from Engelbreth-Holm-Swarm (EHS) mouse sarcoma

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.
