Immunocytochemistry/ Immunofluorescence - Anti-CD272/BTLA antibody [EPR20539] (AB212089)

Immunofluorescent analysis of 100% methanol fixed A20 (mouse reticulum sarcoma cell line) cells labeling CD272/BTLA with ab212089 at 1/100 dilution, followed by by Goat Anti-Rabbit IgG H&L (Alexa Fluor^® 488) (ab150077) secondary antibody at 1/1000 dilution (green). Confocal image showing cytoplasmic and membranous staining on A20 cell line.

The nuclear counter stain is DAPI (blue). Tubulin is detected with Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker (Alexa Fluor^® 594) (ab195889) (red) at 1/200 dilution.

Secondary antibody only control : Used PBS instead of primary antibody, secondary antibody is Goat Anti-Rabbit IgG H&L (Alexa Fluor^® 488) (ab150077) secondary antibody at 1/1000 dilution.

Flow Cytometry - Anti-CD272/BTLA antibody [EPR20539] (AB212089)

Flow cytometric analysis of A20 (mouse reticulum sarcoma cell line) cell line labeling CD272/BTLA with ab212089 at 1/500 dilution (red) compared with a Rabbit IgG, monoclonal [EPR25A] - Isotype Control (ab172730) (black) and an unlabeled control (cells without incubation with primary antibody and secondary antibody) (blue). Goat Anti-Rabbit IgG H&L (Alexa Fluor^® 488) at 1/2000 dilution was used as the secondary antibody.

Total viable cells were gated for the FC image.

Flow Cytometry - Anti-CD272/BTLA antibody [EPR20539] (AB212089)

Flow cytometric analysis of mouse splenocytes labeling CD272/BTLA with ab212089 at 1/500 dilution (right) compared with a Rabbit IgG, monoclonal [EPR25A] - Isotype Control (ab172730) (left). Goat Anti-Rabbit IgG H&L (Alexa Fluor^® 488) at 1/2000 dilution was used as the secondary antibody.

Mouse splenocytes stained with CD3 and ab212089. Total viable cells were gated for the FC image. T cells (CD3+, upper population) show a moderate positive signal while B cells (lower right population in right panel) show stronger positive signal. The expression pattern is also reported in literature (PMID : 19949073).

Lab

Immunoprecipitation - Anti-CD272/BTLA antibody [EPR20539] (AB212089)

CD272/BTLA was immunoprecipitated from 0.35 mg mouse spleen lysate with ab212089 at 1/30 dilution. Western blot was performed from the immunoprecipitate using ab212089 at 1/500 dilution. VeriBlot for IP Detection Reagent (HRP) (ab131366), was used for detection at 1/1000 dilution

Lane 1 : Mouse spleen lysate 10 μg (Input).

Lane 2 : ab212089 IP in mouse spleen lysate.

Lane 3 : Rabbit monoclonal IgG (ab172730) instead of ab212089 in mouse spleen lysate.

Blocking and dilution buffer and concentration : 5% NFDM/TBST.

Exposure time : 1 second.
