特異性：Jo-1 Antigen Shows only the Jo-1 precipitate band when tested using double immunodiffusion against rabbit thymus extract. Specificity is verified by identity of precipitation with CDC-AF reference serum. The titer obtained will vary with the test system; however, undiluted antibody shows a strong Jo-1 precipitate band. Product shows no reactivity at a dilution of 1:100 when tested against purified SSA, Sm/RNP, Scl-70, SSB, and Sm antigens in an ELISA system designed to detect all IgG subclasses.
純度：Single donor human plasma is delipidized and defibrinated. An immunoglobulin fraction is then precipitated and collected.
形状：Purified, Lyophilized Reconstitute with 2ml deionized water.
