Immunocytochemistry/ Immunofluorescence - Anti-Human IgM antibody [EPR20731] - BSA and Azide free (AB228524)

Immunofluorescent analysis of 100% methanol-fixed Raji (human Burkitt's lymphoma cell line) cells labeling IgM with ab212201 at 1/100 dilution, followed by Goat Anti-Rabbit IgG H&L (Alexa Fluor^® 488) (ab150077) secondary antibody at 1/1000 dilution (green). Confocal image showing cytoplasmic staining in Raji cells.

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

-ve control : PBS instead of ab212201, followed by Goat Anti-Rabbit IgG H&L (Alexa Fluor^® 488) (ab150077) secondary antibody at 1/1000 dilution.

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab212201).

Flow Cytometry - Anti-Human IgM antibody [EPR20731] - BSA and Azide free (AB228524)

Flow cytometric analysis of human PBMC (peripheral blood mononuclear cells) cell line labeling IgM with ab212201 at 1/50 (right panel) compared with an isotype control details (ab172730) (left panel). Goat Anti-Rabbit IgG H&L (Alexa Fluor^® 488) (ab150077), at 1/2000 dilution was used as the secondary antibody.

Human PBMCs co-stained with anti-CD19 (Y-axis); only CD19+ population give a positive signal for IgM. Gated on total viable cells.

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab212201).

Immunoprecipitation - Anti-Human IgM antibody [EPR20731] - BSA and Azide free (AB228524)

IgM was immunoprecipitated from 0.35 mg of Raji (human Burkitt's lymphoma cell line) whole cell lysate with ab212201 at 1/30 dilution. Western blot was performed from the immunoprecipitate using ab212201 at 1/1000 dilution. VeriBlot for IP Detection Reagent (HRP) (ab131366), was used for detection at 1/10000 dilution.

Lane 1 : Raji whole cell lysate 10 μg (Input).

Lane 2 : ab212201 IP in Raji whole cell lysate.

Lane 3 : Rabbit monoclonal IgG (ab172730) instead of ab212201 in Raji whole cell lysate.

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

Exposure time : 10 seconds.

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab212201).
