Anti-Fas 抗体 [EPR24898-74] - BSA and Azide free (ab289892)

This data was developed using ab271016, the same antibody clone in a different buffer formulation.

Immunohistochemical analysis of paraffin-embedded sections of mouse thymus labelling Fas with ab271016 at 1/100 dilution followed by  ready to use secondary antibody LeicaDS9800 (Bond™ Polymer Refine Detection). Membranous staining on mouse thymus. Counterstained with Hematoxylin.

Heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0, epitope retrieval solution2) for 20 mins was used. The section was incubated with ab271016 for 30 mins at room temperature. The immunostaining was performed on a Leica Biosystems BOND^® RX instrument. 

Secondary antibody only control: PBS instead of primary antibody followed by LeicaDS9800 (Bond™ Polymer Refine Detection) as a secondary antibody. 

This data was developed using ab271016, the same antibody clone in a different buffer formulation. 

Immunohistochemical analysis of 4% PFA-fixed, 0.2% Triton X-100 permeabilized frozen mouse thymus (fresh) tissue labelling Fas with ab 271016 at 1/100 dilution, followed by Goat Anti-Rabbit IgG H&L (Alexa Fluor^® 488) preadsorbed (ab150081) at 1/1000 dilution (Green).  Positive staining on mouse thymus. The nuclear counter stain was DAPI (Blue).

Secondary antibody only control: Used PBS instead of primary antibody follwed by Goat Anti-Rabbit IgG H&L (Alexa Fluor^® 488) preadsorbed (ab150081) at 1/1000 dilution.  

This data was developed using ab271016, the same antibody clone in a different buffer formulation. 

Fas was immunoprecipitated from mouse thymus tissue lysate with ab271016 at 1/30 dilution (2 μg in 0.35 mg lysates). Western blot was performed from innunoprecipitate using ab271016 at 1/1000 dilution. Secondary antibody VeriBlot for IP secondary antibody(HRP)(ab131366) at 1/5000 dilution. 

Lane 1: Mouse thymus tissue lysate (Input) 10 μg

Lane 2: ab271016 IP in Mouse thymus tissue lysate

Lane 3: Rabbit monoclonal IgG (ab172730) instead of ab271016 in mouse thymus tissue lysate

Exposure time: 5.5 seconds

The 20KDa band could be a degradation or cleavage product, as demonstrated by the use of fresh lysate in the WB data.

This data was developed using ab271016, the same antibody clone in a different buffer formulation. 

5% NFDM/TBST was used as blocking and diluting buffer. 

The observed MW are consistent with what has been described in the literature (PMID: 28883393).

Low expression: stomach, skin (PMID: 31582729; PMID: 11106570).
