2ml-20CBlue IceHumanHuman
This product is derived from human patient serum.
Purified by fractionation of delipidated and defibrinated donor human serum.
Supplied as a lyophilized powder from PBS, pH 7.4, 0.02% sodium azide. Reconstitute with 2ml sterile ddH2O.
Recognizes human ds-DNA. Exhibits strong positive reaction in an anti-dsDNA ELISA system. Shows no reactivity at a dilution of 1:100 when tested against purified Ro/SS-A, La/SS-B, Sm, Sm/RNP, Scl-70 and Jo-1 antigens in an ELISA system designed to detect IgG antibody. Negative for ssDNA in RIA.
Intended for research use only. Not for use in human, therapeutic, or diagnostic applications.
