<p>Plasma cells produce immunoglobulins/antibodies (thousands a second). The immunoglobulin binding specificity is identical to the binding specificity of the BCR on the [[Lymphocytes - WikiBlood#B cells|B cell]] that the cell has differentiated from. This means that when a [[Lymphocytes - WikiBlood#B cells|B cell]] has a BCR that can effectively bind to an antigen the immunoglobulins produced by the plasma cell can bind to that antigen.</p> | <p>Plasma cells produce immunoglobulins/antibodies (thousands a second).
