You mention the following buffer composition for reconstitution: "...20 mM sodium phosphate buffer, with 77 mM sodium chloride, 0.01% BSA, pH 7.0". If I want to refreeze aliquots, would you suggest the same buffer? Isn't sodium phosphate harmful here?
1 answer-
Long-term solution stability studies have not been performed on the microbial source hyaluronidase. However, the bovine source products are stable for up to 1 month at 4 deg. C (500 mM acetate buffer pH 6.0) and several months at - 20 deg. C. Aliquot solutions to store frozen, avoid repeated freeze/thaw cycles. The recommended reconstitution buffer should include 0.01% BSA which acts as a stabilizer, there is no indication that the recommended sodium phosphate/sodium chloride buffer would be inappropriate for freezing.
