Single-cell suspensions were prepared from different lymphoid organs and incubated for 10 min at 10 6 cells/20 ?l on ice in staining buffer (phosphate-buffered saline [PBS] containing 0.5% bovine serum albumin [BSA] and 0.01% NaNstep three) with optimal amounts of fluorescein isothiocyanate-, phycoerythrin-, or biotin-conjugated antibodies. ): S7 (anti-CD43), B3B4 (anti-CD23), and Ly1 (anti-CD5). The following antibodies were prepared: RA3-6B2 (anti-B220), R33- (anti-IgM), 1.3-5 (anti-IgD), and Cfo-1 (anti-Thy1.2). Flow cytometric analysis was performed on a FACScan cytometer (Becton Dickinson & Co., Mountain View, Calif.).
Study of B-cell proliferation and you can upregulation out-of activation indicators.
Splenic B tissues was refined by destruction away from low-B muscle towards MACs articles (Miltenyi Biotec, Bergisch Gladbach, Germany) which have anti-CD43 antibody coupled to help you magnetic beads (Miltenyi Biotec) because described in earlier times (17). Continue reading
