Our Abpromise guarantee covers the use of ab21045 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|ELISA||ELISA: Use at an assay dependent dilution.|
|Sandwich ELISA||sELISA: Use a concentration of 5 µg/ml. For sandwich ELISA, use this antibody as Capture at 5 µg/ml with Rabbit polyclonal to Factor IX (ab23335) as Detection.|
|WB||WB: Use at an assay dependent dilution. Detects a band of approximately 52 kDa (predicted molecular weight: 52 kDa). This antibody recognizes an epitope on the light chain. On Western blot using reducing conditions, the molecular weight of the light chain is 23kDa. Dilution optimised using Chromogenic detection. On Western blot using non-reducing conditions, the molecular weight of the intact Factor IX is 57kDa.|
- FunctionFactor 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 specificitySynthesized primarily in the liver and secreted in plasma.
- Involvement in diseaseDefects 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 similaritiesBelongs to the peptidase S1 family.
Contains 2 EGF-like domains.
Contains 1 Gla (gamma-carboxy-glutamate) domain.
Contains 1 peptidase S1 domain.
- DomainCalcium binds to the gamma-carboxyglutamic acid (Gla) residues and, with stronger affinity, to another site, beyond the Gla domain.
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.
