LONG SHELF-LIFE KITS AND METHODS FOR STANDARDIZING, VERIFYING, CALIBRATING OR RECALIBRATING DETECTION OF LIPOPROTEIN-ASSOCIATED PHOSPHOLIPASE A2

摘要

Long shelf-life kits, value-assigned solutions, and methods for standardizing, verifying, calibrating or recalibrating detection of lipoprotein-associated phospholipase A2 having using them are described herein. In particular, described herein are methods of using solutions of rLp-PLA2 that are stable for an extended period of time to standardize, verify, calibrate or recalibrate assays for Lp-PLA2.

1. A method of recalibrating a calibration curve for detection of lipoprotein-associated phospholipase A2 (Lp-PLA2) from a biological sample using a value-assigned solution of recombinant Lp-PLA2 having a long shelf life, the method comprising:
detecting a first signal from a value-assigned solution having a first predetermined concentration of a recombinant Lp-PLA2 in a buffer solution, wherein the buffer solution comprises a detergent forming a plurality of micelles that stabilize the recombinant Lp-PLA2; and transforming the calibration curve using the first signal.
