Immunoglobulin somatic variation; studies of receptor editing in a human B cell lymphoma.

Abstract excerpt

In order to study mechanisms of immunoglobulin somatic variation in committed immunoglobulin (Ig) expressing B cells, we used the fluorescent activated cell sorter to isolate rare variants from a surface Ig positive (sIg+) diffuse large cell B lymphoma cell line (mu lambda+). These variants were either negative for sIg expression (sIg-) or expressed sIg which differed from the original parental tumor cell line,...
