<p>Disclosed are: a method for identifying/analyzing a gene for an antibody in one cell derived from a human; a technique for producing an antibody derived from an identified one B cell; and others. A gene for an antibody specific to a melanoma antigen is analyzed/identified at a one-cell level by using an immortalized B cell produced from peripheral blood monocytes from a melanoma patient or a primary B cell included in the peripheral blood monocytes. It is found that B cells capable of producing a specific antibody can be separated on one cell by one cell basis by staining the B cells with a GST-labeled melanoma-specific cancer antigen MAGE1, an Alexa-labeled anti-GST antibody and a PE-labeled anti-human IgG antibody and carrying out the single cell sorting of the stained B cells. Further, a practical technique for extracting total RNA from the separated one B cell and cloning a gene for a specific antibody into the total RNA efficiently can be established.</p> |
