Human collagen type IV from placenta.Human collagen type I-III, V, VI (<5%). Non collagen proteins (<0.5%).
Purified protein - liquid
Salt and alcohol precipitations, DEAE chromatography. Purity and retention of native helical structure was controlled by SDS-PAGE, ORD measurement, ability to form microfibrils and by reaction with anti-collagen type specific monoclonal antibodies.
0.09% Sodium Azide (NaN3)
SDS PAGE: >95%
Approx. Protein Concentrations
Total protein concentration 1.0mg/ml.
Phosphate buffered saline
Store at +4oC or at -20oC if preferred. Storage in frost-free freezers is not recommended. This product should be stored undiluted. Avoid repeated freezing and thawing as this may denature the protein. Should this product contain a precipitate we recommend microcentrifugation before use.
