Antibody Production (AbP), Functional Studies (Func), Protein Interaction (PI), Standard (STD)
特异性
Optimal preservation of protein structure, post-translational modifications and functions.
产品特性
Recombinant human Interleukin-27 / IL27A protein expressed in HEK293.
Produced with end-sequenced ORF clone
Tested for bioactivity.
纯度
Purity is > 95 % , as determined by Coomassie stained SDS-PAGE.
内毒素水平
Less than 0.01 ng per μg protein as determined by the LAL method.
Biological Activity Comment
The ED50 is 5 - 10 ng/ml, corresponding to a specific activity of 1.0 - 2.0 x 10^5 units/mg, determined by inhibition of IL-2 production induced by mouse IL-27 in mouse splenocytes activated with anti-CD3 and anti-CD28 antibodies.
Recombinant human proteins can be used for: Native antigens for optimized antibody production Positive controls in ELISA and other antibody assays Protein-protein interaction In vitro biochemical assays and cell-based functional assays
