Binding of rCsBAFF to lymphocytes.

Abstract

<p>Tongue sole lymphocytes were incubated with rCsBAFF (A and B) or rGST (D and E), and the cells were treated with FITC-labeled antibody (A and D, for detecting His-tagged protein) or RBITC-labeled antibody (B and E, for detecting cell-surface IgM). The cells were observed under a fluorescence microscope. C, merge of A and B; F, merge of D and E. Magnification, 400 ×.</p
