Product overview
- Human COL18A1 Antibody Pair is a matched pair of unconjugated recombinant rabbit monoclonal capture and detection antibodies used to quantify Human COL18A1 in sandwich ELISAs and many other pair-based applications.
- The pair can be used in variety of assays and platforms including but not limited to:
- - Sandwich ELISA
- - FRET/TR-FRET/HTR
- - Meso Scale Discovery® (MSD®)
- - Luminex® and bead-based assays
- - AlphaLISA®/AlphaScreen®
- - DELFIA® immunoassays
- - Simoa® and Single Molecule Counting (SMC™) immunoassays
- - Multiplex
- Our antibody pairs are supplied in a carrier-free format that is conjugation-ready:
- - Buffer free of BSA, sodium azide, and glycerol for higher conjugation efficiency.
- - Concentration of ~1 mg/ml as measured by the protein A280 method.
- Use our conjugation kits for antibody conjugates that are ready-to-use in as little as 20 minutes with
- We can label antibodies for you: get in touch today to discuss how we can help accelerate your assay development with custom conjugation services.
- Pairs are screened in biological samples, including plasma and serum, to ensure specificity in complex samples.
- Please note:
- The recommended antibody orientation is based on internal optimization in sandwich ELISA. Antibody orientation is assay dependent and needs to be optimized for each assay type.
- The range provided for this antibody pair is based on initial sandwich ELISA validation data using recombinant protein. Performance and range of the antibody pair will depend on the specific characteristics of your assay, including standard protein selection.
- We guarantee the product works in sandwich ELISA, but we do not guarantee the sensitivity or dynamic range of the antibodies in other assays.

Function
COLA18A probably plays a major role in determining the retinal structure as well as in the closure of the neural tube.
Endostatin potently inhibits endothelial cell proliferation and angiogenesis. May inhibit angiogenesis by binding to the heparan sulfate proteoglycans involved in growth factor signaling. -
Tissue specificity
Present in multiple organs with highest levels in liver, lung and kidney. -
Involvement in disease
Defects in COL18A1 are a cause of Knobloch syndrome (KNO) [MIM:267750]. KNO is an autosomal recessive disorder defined by the occurrence of high myopia, vitreoretinal degeneration with retinal detachment, macular abnormalities and occipital encephalocele. -
Sequence similarities
Belongs to the multiplexin collagen family.
Contains 1 FZ (frizzled) domain.
Contains 1 TSP N-terminal (TSPN) domain. -
Post-translational
modificationsProlines at the third position of the tripeptide repeating unit (G-X-Y) are hydroxylated in some or all of the chains. -
