Sandwich ELISA quantitative detection kit for Mouse CD30L in serum, body fluids, tissue homogenates and cell culture supernates.The human CD30L(CD153) gene is located at 9q33. It contains 4 exons and spans more than 17.1 kb. CD153 is expressed on the surface of B cells and this expression is upregulated upon CD154 (CD40LG), IL4, and B-cell receptor engagement. In these cells, engagement of CD153 by T cell CD30 inhibits immunoglobulin class switch recognition as well as IgG, IgA, and IgE production, suggesting that this 'reverse signaling' modulates the CD154-dependent switching of B cells into the pool producing IgG, IgA, and IgE. Additionally, recombinant human CD30L enhanced the proliferation of CD3 -activated T cells, but induced differential responses, including cell death, in several CD30-positive lymphoma-derived cell lines.The standard product used in this kit is recombinant mouse CD30L with the molecular mass of 30-45kD.
