Should I heat the product P4929-25U after resuspension to make aliquots? If yes, then how long and at what temperature? Thank you!
1 answer-
This product is soluble in water or neutral buffer. Solubility is no longer considered part of the specifications, but it was previously reported to be soluble at 20 mg/mL in 0.1 M Tris-HCl, pH 8.8. Heat is not necessary to solubilize the product; dissolving in an appropriate solvent is the recommended method for resuspension.
