Fig. 7From: Novel fusion proteins for the antigen-specific staining and elimination of B cell receptor-positive cell populations demonstrated by a tetanus toxoid fragment C (TTC) model antigenBinding analysis of recombinant TTC and TTC-FITC on isolated PBMCs. Surface staining of CD27+ memory B cells (a) and intracellular staining of CD27++CD38++ plasma cells (c) using recombinant TTC (10 nM) and anti-His5 Alexa Fluor 488 antibody (1:100). Surface staining of CD27+ memory B cells (b) and intracellular staining of CD27++CD38++ plasma cells (d) using a FITC-coupled TTC peptide (1:25)Back to article page
