Introduction:
APOA1 (Apolipoprotein A-1) is a human protein with a specific role in lipid metabolism being the main protein component of HDL in the plasma. APOA1 promotes cholesterol efflux from tissues to the liver for excretion. Furthermore, APOA1 is a cofactor for LCAT, which is responsible for the formation of most plasma cholesteryl esters. In addition, APOA1 activates spermatozoa motility as part of the SPAP complex. The APOA1 gene is strongly linked with two other apolipoprotein genes on chromosome 11. Defects in the APOA1 gene are linked to HDL deficiency including Tangier disease, and with systemic non-neuropathic amyloidosis. High levels of APOA1 are linked to the manifestation of asthma and atopy.

Description:
APOA1 Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 264 amino acids (25-267 a.a.) and having a molecular mass of 30.3kDa. APOA1 is fused to 20 a.a. His-Tag at N-terminus and purified by proprietary chromatographic techniques.

Source:
Escherichia Coli.




Physical Appearance:
Sterile filtered colorless solution.

Formulation:
The APOA1 solution containing 20mM Tris-HCl buffer (pH8.0) and 10% glycerol.


Stability:
APOA1 although stable at 4°C for 1 week, should be stored below
-18°C.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
