Bovine placenta


Bovine collagen type VI 90%


Lyophilized, salt-free


Collagen was extracted from washed dissected tissue into dilute acetic acid after pepsin treatment. Collagen type VI was purified by using differential salt precipitation


ELISA, Immunoprecipitation, Western Blotting


Collagen type VI dissolves very slowly in 0.5 M acetic acid and requires both vigorous mixing and time.

Add small amount of 0.5 M acetic acid, pH 2.5 and use Potter homogenizer (or similar) to break up the protein cake into suspension. Add 0.5 M acetic acid, pH 2.5 to yield 0.1 mg/ml concentration and use vigorous stirring for several days.

Concentration higher than 0.1 mg/ml in acetic acid requires even longer time. Use 6M urea (or other chaotropic agent) if application allows it.


Lyophilized protein: shipping at ambient temperature, long term storage (2 years) at -20°C or lower. Storage of reconstituted protein 1 month at +4°C
