Chromogenic substrate for factor IXa. For research use only.

Use: All research studies and protocols where a source of chromogenic substrate for Factor IXa is required. Factor IXa chromogenic activity is dramatically enhanced by 33% Ethylene Glycol.

Origin: Synthetic Chromogenic substrate, specific for Factor IXa, highly purified and stabilized.

Specificity: Recommended substrate for the chromogenic measurement of factor IXa.

Presentation: Vial containing 25 mg of Biophen CS-51(09), lyophilized in presence of mannitol as a bulking agent.

Reconstitution: According to the research protocol used, the Biophen CS-51(09) chromogenic substrate can be restored with variable volumes of distilled water; for example 5 mL can be used for a substrate concentration of 5 mg/mL, or 20 ml for a substrate concentration of 1.25 mg/mL, etc.

Peptide sequence: CH₃SO₂-(D-)CHG-Gly-Arg-pNa, AcOH

Purity grade: > 95%.

Molecular weight: 628.7.

Free pNA content: < 0.05%.

Respective reactivities:

Assay conditions must be established for making the substrate totally specific for factor IXa.

Stability:

• Restored: 7 days at room temperature. 1 month at 2-8^°C. - Do not freeze.
• Lyophilized: Until the expiration date printed on the vial.
