Abstract:
The second step of immunoglobulin gene alteration consists of somatic hypermutation and class switch recombination. 80th are regulated by activation-induced cytidine deaminase (AID). Methods: Study on possible application of class switch recombination assays for immunoglobulin gene alteration via AID. Cell based assays using AID B lymphocyte and NIH3T3 cell carrying switch substrate; gene transfer using retrovirus system; FACS analysis; PCR and ELISA. Results: DNA sequencing for S region and gamma1CT are the most sensitive and accurate assays. However, gamma1CT assay seemed to be more reliable and applicable. Others are accurate assays but less applicable. Conclusion: gamma1CT determination is the best class switch recombination assay for immunoglobulin gene alteration via AID.
