Ancillary Reagent Kit Available  

DY008, DuoSet ELISA Ancillary Reagent Kit 2 -

This DuoSet ELISA Development kit contains the basic components required for the development of sandwich ELISAs to measure natural and recombinant human C1q and Tumor Necrosis Factor-related Protein 3 (C1qTNF3). The suggested diluent is suitable for the analysis of most cell culture supernate, serum, and plasma samples. Diluents for complex matrices, such as serum and plasma, should be evaluated prior to use in this DuoSet.

Background: CTRP3/C1qTNF3/CORS26

C1qTNF proteins constitute a highly conserved family of Acrp30/Adiponectin paralogs that share a modular organization comprising an N-terminal signal peptide, a short variable region, a collagenous domain and a C-terminal globular domain. C1qTNF proteins are predicted to have trimeric structures that assemble into hexameric and higher order molecular forms. C1qTNF3, also known as CORS26, is predominantly expressed in cartilage and is induced in mature adipocytes. C1qTNF10, also known as C1qL2, is a protein that shows 28% - 30% sequence identity with C1q subunits A, B, and C. It is predicted to contain one collagen-like and C1q domain. Mouse and human C1qTNF10 share over 90% amino acid sequence identity.
