Abstract: | Amplification of human immunoglobulin has many potential applications such as analysis of clonality, isolation of immunogenic antigens and antigen-specific immunotherapy. Here we describe a method for amplification of human immunoglobulin heavy and light chains from single B lymphocytes or plasma cells. Cells are isolated by FACS, and Ig is amplified by semi-nested RT–PCR. The method is versatile, sensitive and reliable: it provides appropriately paired heavy and light chains, requiring as little as 2 days to produce amplified Fab DNA from human tissues. |
