应用备注
-
For flow cytometric applications, a three step labeling procedure is recommended for amplifying signal. Suggested protocol for 3-step staining using concanavalin-A-stimulated peripheral blood mononuclear cells method:
1. Incubate 100 µl concanavalin-A-stimulated 3-day peripheral blood mononuclear cells (1x10^6) with primary (unconjugated) antibody for 20-30 minutes at room temperature.
2. Add 2 mls of 1X lysing buffer (10X Pharm Lyse™ Lysing Buffer, Cat. No. 555899) and incubate for 10-15 minutes. Centrifuge and aspirate.
3. Wash once with PBS/0.1% sodium azide/1% heat-activated fetal bovine serum (PBS-FBS). Centrifuge and aspirate.
4. Add biotinylated goat anti-mouse Ig (Cat. No. 553999) and incubate for 20-30 minutes at room temperature.
5. Wash once with PBS-FBS. Centrifuge and aspirate.
6. Add SAV-PE (Cat. No. 554061) and incubate for 20-30 minutes in the dark at room temperature.
7. Wash once with PBS-FBS. Centrifuge and aspirate. Resuspend in 0.5 ml of PBS-FBS and analyze by flow cytometry. -

背景
-
Reacts with the cytolytic T lymphocyte-associated antigen, CTLA-4. CTLA-4 is transiently expressed on activated CD28+ T cells and binds to CD80 and CD86 present on antigen presenting cells (APC) with high avidity. This interaction appears to deliver a negative regulatory signal to the T cell. There are recent reports that indicate that CTLA-4 is also expressed on B cells when cultured with activated T cells, suggesting a possible role of CTLA-4 in the regulation of B-cell response. Immobilized BNI3.1 enhances T-cell proliferation induced by CD3 and CD28. Recent studies have showed that CD152 can be expressed by regulatory T (Treg) cells. It has been found this antibody can stain the intracellular CD152 on the Treg cells after fixation and permeabilization of cells.
