Verichem Laboratories' HDL Cholesterol Verifier Kit

Verichem Laboratories launched its HDL Cholesterol Verifier Kit, which is intended for the calibration verification of high density lipoprotein and low density lipoprotein cholesterol tests. The kit contains HDL and LDL cholesterol and other liquid components from human serum without interfering substances like surfactants, glycols, and azide. It also contains a blend of "highly purified" human serum albumin, human serum globulin, and bovine gamma globulin in saline, the company said.

Using purified source components eliminates matrix variations, allowing for lot-to-lot reproducibility and consistency, the company added. The HDL and LDL cholesterol targets are determined using reference method certified calibration materials, and the material's pH, matrix composition, and protein balance are kept constant. 

The kit comes with five milliliters of material at each concentration level and have shelf-life stability of 14 months when stored between -15 and -25 degrees Celsius. It can be frozen and thawed for up to 10 cycles.
