Product overview
- Human Factor IX Antibody Pair is a matched pair of unconjugated recombinant rabbit monoclonal capture and detection antibodies used to quantify Human Factor IX 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
Factor IX is a vitamin K-dependent plasma protein that participates in the intrinsic pathway of blood coagulation by converting factor X to its active form in the presence of Ca(2+) ions, phospholipids, and factor VIIIa. -
Tissue specificity
Synthesized primarily in the liver and secreted in plasma. -
Involvement in disease
Defects in F9 are the cause of recessive X-linked hemophilia B (HEMB) [MIM:306900]; also known as Christmas disease.
Note=Mutations in position 43 (Oxford-3, San Dimas) and 46 (Cambridge) prevents cleavage of the propeptide, mutation in position 93 (Alabama) probably fails to bind to cell membranes, mutation in position 191 (Chapel-Hill) or in position 226 (Nagoya OR Hilo) prevent cleavage of the activation peptide.
Defects in F9 are the cause of thrombophilia due to factor IX defect (THR-FIX) [MIM:300807]. A hemostatic disorder characterized by a tendency to thrombosis. -
Sequence similarities
Belongs to the peptidase S1 family.
Contains 2 EGF-like domains.
Contains 1 Gla (gamma-carboxy-glutamate) domain.
Contains 1 peptidase S1 domain. -
Domain
Calcium binds to the gamma-carboxyglutamic acid (Gla) residues and, with stronger affinity, to another site, beyond the Gla domain. -
Post-translational
modificationsActivated by factor XIa, which excises the activation peptide.
The iron and 2-oxoglutarate dependent 3-hydroxylation of aspartate and asparagine is (R) stereospecific within EGF domains. -
Cellular localization
