Protein Unfolding allow use of Commercial Antibodies in an Apolipoprotein M sandwich ELISA.
(2015) In Journal of Lipid Research 56(3). p.754-759- Abstract
- Apolipoprotein M (apoM) is a member of the lipocalin super family and circulates in plasma attached to high density lipoprotein particles. ApoM plays a role in cholesterol metabolism and has recently been identified as transporter for the signaling lipid Sphingosine-1-Phosphate (S1P) in plasma. S1P is implicated in several inflammatory diseases such as Multiple Sclerosis and Rheumatoid Arthritis. The ability to accurately measure apoM is crucial for investigating its biological functions and possible clinical implications. However, reliable commercial methods have been lacking so far. Therefore we have developed an assay that specifically recognizes human apoM in plasma using commercially available reagents. Commercial apoM antibodies were... (More)

The ability to accurately measure apoM is crucial for investigating its biological functions and possible clinical implications. However, reliable commercial methods have been lacking so far. Therefore we have developed an assay that specifically recognizes human apoM in plasma using commercially available reagents. Commercial apoM antibodies were screened for compatibility in a sandwich ELISA-based assay. One optimal pair of antibodies was chosen and sample preparation, buffers and incubation times were optimized to generate a simple and easily reproducible method. Validation and comparison to a previously described ELISA for apoM confirmed that the assay displays a high degree of sensitivity, specificity and precision. Our results show that commercially available antibodies can be used to accurately measure human plasma apoM. This method can be implemented in every laboratory and will help promote high quality research. (Less)
