Lyophilized from 0.02 M ammonium bicarbonate and may contain traces of buffer salts
Storage Instruction:
Store at 2-8°C on dry atmosphere. After reconstitution with phosphate buffer, pH 7.0 (contains 0.15 M NaCl), aliquot and store at 2-8°C.
Note:
Universal Precautions. Safe laboratory practices should be used when handling this material.
Background Information:
By PAGE, the product shows one band at 660 kDa. Identity also confirmed by cellulose acetate electrophoresis that gives a single band with a1 electrophoretic mobility and also Ouchterlony Immunodiffusion. (Using the PAGE method, certain conditions can also show a sub-unit of thyroglobulin as a second band at 330 kDa.)
