Purification of lipoprotein cholesterol for use as a cholesterol reference material |
摘要 |
A method for the purification of lipoprotein cholesterol. The method involves the steps of adsorbing lipoprotein material on a silica adsorbant, eluting the adsorbed lipoprotein with water at a pH of about 10 to 11.5, adjusting the salt concentration to about less than 0.05M, heating the lipoprotein to about 50 DEG to 100 DEG C. for a period of about 5 minutes to 24 hours, adding an alkaline carbonate and alkaline earth salt to form a precipitate and removing the precipitate, adjusting the pH from about 6.5 to 9.0 and recovering purified lipoprotein cholesterol. Also a method for using the cholesterol as a cholesterol reference material.
