Rabbit Coagulation Factor IX, Active Protein, Cat#RPU60695
SDS-PAGE
Coagulation Factor IX, also known as Christmas Factor, is a secreted by the liver and plays a key role in the activation of the intrinsic clotting cascade. Factor IX consists of a Gla domain, two tandem EGF-like domains, an activation peptide, and an S1 serine protease domain. Mature human Factor IX shares approximately 81% amino acid sequence identity with mouse and rat Factor IX. Alternative splicing generates an additional isoform that lacks the first EGF-like domain. The activity of recombinant rabbit Coagulation Factor IX is measured by its ability to cleave a fluorogenic peptide substrate Mca-RPKPVE-Nval-WRK(Dnp)-NH2 in the assay buffer 100 mM Tris, 150 mM NaCl, 10 mM CaCl2, 0.05% (w/v) Brij-35, pH 8.0. The Coagulation Factor IX is diluted to 100 ug/ml in assay buffer, then activated with a final concentration of 10 ug/ml Thermolysin at 37 °C for 90min. Adding a final concentration of 10 mM 1,10 Phenanthroline to stop the activation. The activated Coagulation Factor IX is diluted to 6 ug/mL in assay buffer. Loading into a black well plate 50 uL of 6 ug/mL Coagulation Factor IX and start the reaction by adding 50 uL of 20 uM substrate, with a substrate blank containing 50 uL assay buffer, 50 uL substrate, and no Coagulation Factor IX. Then read at 320/405 nm in kinetic mode for 5 minutes. The specific activity of recombinant rabbit Coagulation Factor IX is > 20 pmol/min/ug.

Let customers speak for us

from 218 reviews

We were very pleased with Biomatik’s performance on a custom recombinant protein project earlier this summer. Communication throughout the project was excellent, technical questions were addressed promptly, and the supporting analytical and QC data were clear and comprehensive. The recombinant protein was produced to the requested specifications and delivered on schedule. Based on this experience, we have chosen Biomatik for an additional custom protein production project and would be pleased to work with them again.
