Canine Factor IX is a functional coagulation factor. Canine Factor IX shortens whole blood clotting time and activated partial thromboplastin time, and restores coagulation function. After intramuscular administration via rAAV vector in hemophilia B dogs, Canine Factor IX maintains a sustained circulating level for at least 1 year, partially corrects the hemophilia B phenotype in a dose-dependent manner, and its plasma expression persists for more than 17 months. Canine Factor IX is applicable to relevant research on hemophilia B.

Description

Canine Factor IX is a functional coagulation factor. Canine Factor IX shortens whole blood clotting time and activated partial thromboplastin time, and restores coagulation function. After intramuscular administration via rAAV vector in hemophilia B dogs, Canine Factor IX maintains a sustained circulating level for at least 1 year, partially corrects the hemophilia B phenotype in a dose-dependent manner, and its plasma expression persists for more than 17 months. Canine Factor IX is applicable to relevant research on hemophilia B[1][2].

In Vitro

Canine Factor IX (104-105 vector particles/cell; 36 h post-transduction) was secreted in biologically active form following transduction of HEK-293 cells with AAV-CMV-cF.IX vector, measurable via ELISA of cell supernatants[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

ELISA Assay[2]

Cell Line: HEK-293 cells
Concentration: 104, 105 vector particles/cell
Incubation Time: 36 h post-transduction
Result: Resulted in detectable secretion of biologically active canine Factor IX into cell supernatants.
In Vivo

Canine Factor IX (1.3 × 1011-8.5 × 1012 vector particles/kg; intramuscular injection; single administration) enables dose-dependent, stable long-term expression of biologically active canine F.IX[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Outbred dogs (male and female; 2, 4, 8 months old; 5.7-20 kg; spontaneous severe hemophilia B with undetectable endogenous F.IX)[2]
Dosage: 1.3 × 1011; 1.1 × 1012; 3.4 × 1012; 3 × 1012; 8.5 × 1012 vector particles/kg
Administration: i.m.; single dose
Result: Was stably expressed in plasma in a dose-dependent manner, reaching up to 69 ng/ml, WBCT and APTT were persistently shortened, immune responses against cFIX were absent or transient, and no local or systemic toxicity was observed.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
