HumanPOSTN is a matched pair of unconjugated recombinant rabbit monoclonal capture and detection antibodies used to quantify Human POSTN in sandwich ELISAs and many other pair-based applications.
Our RabMAb® technology is a patented hybridoma-based technology for making rabbit monoclonal antibodies. For details on our patents, please refer to RabMAb® patents.
The pair can be used in variety of assays and platforms including but not limited to:
- Sandwich ELISA
- Meso Scale Discovery® (MSD®)
- Bead-based assays
- DELFIA® immunoassays
- Simoa® and Single Molecule Counting (SMC™) immunoassays
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 <1 minute hands-on-time and 100% antibody recovery: available for fluorescent dyes, HRP, biotin and gold.
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.
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.

Components 10 x 96 tests Human POSTN Capture Antibody (unconjugated) 1 x 100µg Human POSTN Detector Antibody (unconjugated) 1 x 100µg
FunctionBinds to heparin. Induces cell attachment and spreading and plays a role in cell adhesion. May play a role in extracellular matrix mineralization.
Tissue specificityWidely expressed with highest levels in aorta, stomach, lower gastrointestinal tract, placenta, uterus and breast. Up-regulated in epithelial ovarian tumors. Not expressed in normal ovaries. Also highly expressed at the tumor periphery of lung carcinoma tissue but not within the tumor. Overexpressed in breast cancers.
Sequence similaritiesContains 1 EMI domain.
Contains 4 FAS1 domains.
modificationsGamma-carboxyglutamate residues are formed by vitamin K dependent carboxylation. These residues are essential for the binding of calcium.
