Descripción

Factor Va (human) Native Protein, RP-43128, from Invitrogen.

RP-43128 contains native human Factor Va protein. RP-43128 may be used as a positive control in many immunological assays. The RP-43128 protein molecular weight is ∽168 kDa. RP-43128 has an Extinction Coefficient (E^1% 1cm, 280 nm) of 17.4 and shows a specific activity of 3320 U/mg. This specific activity was determined by a Factor V clotting assay, where 1 U (unit) is equivalent to the Factor V activity in 1 ml of normal human plasma. The product is of human blood/plasma origin. Although the starting material was tested prior to initiation of the manufacturing process, and was found negative or nonreactive for anti-HIV-1/2, HIV-1 antigen(s), HBsAg, STS, anti-HCV, anti-HBcore and anti-HTLV I & II, extreme caution should be used when handling this material as there is a margin of error in all tests, and testing does not always disclose pathogens or other harmful substances contained in blood/plasma products. This product is to be used for IN VITRO research purposes only, and is not intended for clinical or diagnostic use!
