Factor VIII Paired Antibody Set

F8C-EIA – Factor VIII:C Paired Antibody Set – 4 plate set

SKU: F8C-EIA Categories: Antibodies, Paired Antibody Sets, Factor VIII Products, Factor VIII Antibody, Factor VIII EIA Tags: Factor VIII, Products, Antibodies, Factor VIII Paired Antibody Set

Description

Factor VIII Paired Antibody Set

Affinity’s Factor VIII Paired Antibody Set consists of matched capture and detecting antibodies that have been titrated and optimized for use in sandwich style ELISA assays. The product as provided contains sufficient capture and detecting antibodies for four full 96-well microplates and contains a detailed protocol sheet containing directions for use, recipes for solutions and sources for additional materials required. This Factor VIII Paired Antibody Set is intended to facilitate the end user in establishing an “in-house” immunoassay for research purposes only and must not be used for diagnostic applications.  Assay validation is the responsibility of the end user.


Product Code: F8C-EIA

Supplied Materials:

  1. Capture Antibody (F8C-EIA-C): One yellow-capped vial containing 0.4 ml of polyclonal affinity purified anti-Factor VIII antibody for coating plates.
  2. Detecting Antibody (F8C-EIA-D):  One red-capped tube containing 0.4 ml of peroxidase conjugated affinity-purified polyclonal anti-Factor VIII antibody for detection of captured Factor FVIII.

Description of Factor VIII (FVIII)

Factor VIII (formerly referred to as antihemophilic globulin and Factor VIII:C) is a large glycoprotein (320 kDa) that circulates in plasma at approximately 200 ng/ml. Synthesized in the liver, the majority of Factor VIII is cleaved during expression, resulting in a heterogeneous mixture of partially cleaved forms of FVIII ranging in size from 200-280 kDa. The FVIII is stabilized by association with von Willebrand Factor to form a FVIII-vWF complex required for the normal survival of FVIII in vivo (t1/2 of 8-12 hours).

F.VIII is a pro-cofactor that is activated through limited proteolysis by thrombin. In this process F.VIIIa dissociates from vWF to combine with activated Factor IX, calcium and a phospholipid surface where it is an essential cofactor in the assembly of the Factor X activator complex. Once dissociated from vWF, FVIIIa is susceptible to inactivation by activated Protein C and by non-enzymatic decay.

Hemophilia A is a congenital bleeding disorder resulting from an X-chromosome-linked deficiency of FVIII. The severity of the deficiency generally correlates with the severity of the disease. Some Hemophiliacs (~10%) produce a FVIII protein that is partially or totally inactive. The production of neutralizing antibodies to FVIII also occurs in 5-20% of Hemophiliacs 1-3.
