The purified protein is supplied as 0.25 mg in a lyophilized form. The collagen may be reconstituted by adding 500mM Acetic Acid. The collagen may be transferred into physiological buffers by dialysis at 2-8 degree C. Purified collagen may be stored at 2-8 degree C for several months without appreciable loss of activity. For long-term storage, the purified collagen may be aliquoted and stored at -20 degree C. Avoid repeated freezing and thawing.
