Anti-CD74 抗体 [EPR25399-94] (ab289885)

Immunohistochemical analysis of paraffin-embedded mouse spleen tissue labeling CD74 with ab289885 at 1/2000 dilution, followed by ready to use LeicaDS9800 (BOND™ Polymer Refine Detection). Positive staining on mouse spleen (PMID: 30191677). Counter stained with Hematoxylin. The section was incubated with ab289885 for 30 mins at room temperature.

Heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0, epitope retrieval solution2) for 20 mins was used.

Secondary antibody only control: Used PBS instead of primary antibody, secondary antibody is ready to use LeicaDS9800 (BOND™ Polymer Refine. Detection) was used.

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

Exposure times: 

Lanes 1-2: 10 seconds;

Lanes 3-6: 114 seconds

The observed MW are consistent with what has been described in the literature (PMID: 19413900).

Negative control: mouse kidney (PMID: 28219888).

We observe an unknown band at around 60kDa. 

Immunofluorescent analysis of 80% methanol fixed, 0.1% Triton X-100 permeabilized A20 (mouse reticulum sarcoma cell line) cells labeling CD74 with ab289885 at 1/100 dilution, followed by Goat Anti-Rabbit IgG H&L (Alexa Fluor^® 488) (ab150081) secondary antibody at 1/1000 dilution (green). Confocal image showing cytoplasmic staining in A20 cell line. The nuclear counter stain is DAPI (blue).

Tubulin was labeled using ab195889 Anti-alpha Tubulin mouse monoclonal antibody - Microtubule Marker (Alexa Fluor^® 594) at 1/200 dilution (red).

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

Immunohistochemical analysis of 4% PFA-fixed, 0.2% Triton X-100 permeabilized frozen mouse spleen (fresh) tissue labelling CD74 with ab289885 at 1/500 dilution, followed by ab150081 Goat Anti-Rabbit IgG H&L (Alexa Fluor^® 488) secondary antibody at 1/1000 dilution (Green). Positive staining on mouse spleen. The nuclear counterstain is DAPI (Blue).

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

CD74 was immunoprecipitated from mouse spleen tissue lysate with ab289885 at 1/30 dilution (2 μg in 0.35 mg lysates). Western blot was performed from the immunoprecipitate using ab289885 at 1/1000 dilution. VeriBlot for IP secondary antibody (HRP)(ab131366) at 1/5000 dilution was used as secondary antibody.

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

Lane 2: ab289885 IP in Mouse spleen tissue lysate

Lane 3: Rabbit monoclonal IgG (ab172730) instead of ab289885 in mouse spleen tissue lysate

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

Exposure time: 6 seconds.

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

Exposure time: 

Lane 1: 6 seconds;

Lanes 2: 59 seconds
