 ab218230 Anti-beta 2 Microglobulin antibody [EPR21752-214]  was shown to specifically react with beta 2 Microglobulin in wild-type HepG2 cells. Loss of signal was observed when knockout cell line ab262325 (knockout cell lysate ab256846) was used. Wild-type and beta 2 Microglobulin knockout samples were subjected to SDS-PAGE. ab218230 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) were incubated overnight at 4°C at 1 in 500 dilution and 1 in 20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye^® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye^® 680RD) preadsorbed (ab216776) secondary antibodies at 1 in 20000 dilution for 1 hour at room temperature before imaging.

Immunohistochemical analysis of paraffin-embedded human kidney tissue labeling beta 2 Microglobulin with ab218230 at 1/4000 dilution, followed by a ready to use Goat Anti-Rabbit IgG H&L (HRP) secondary antibody. Positive staining on endothelial cells of human kidney is observed. Counter stained with Hematoxylin.
Secondary antibody only control: Used PBS instead of primary antibody, secondary antibody is a ready to use Goat Anti-Rabbit IgG H&L (HRP).

Heat mediated antigen retrieval was performed using Tris/EDTA buffer pH 9.0 before commencing with IHC staining protocol.

Flow cytometric analysis of 4% paraformaldehyde-fixed, 90% methanol permeabilized HepG2 (human liver hepatocellular carcinoma cell line) cell line labeling beta 2 Microglobulin with ab218230 at 1/500 dilution (red) compared with a Rabbit monoclonal IgG - Isotype control (ab172730) (black) and an unlabeled control cells incubated with secondary antibody only) (blue). Goat anti rabbit IgG (Alexa Fluor^® 488, ab150077), at 1/2000 dilution was used as the secondary antibody.

Beta 2 Microglobulin was immunoprecipitated from 0.35 mg HeLa (human epithelial cell line from cervix adenocarcinoma) whole cell lysate with ab218230 at 1/30 dilution. Western blot was performed from the immunoprecipitate using ab218230 at 1/1000 dilution. VeriBlot for IP Detection Reagent (HRP) (ab131366), was used for detection at 1/5000 dilution.

Lane 1: HeLa whole cell lysate 10 µg (Input).
Lane 2: ab218230 IP in HeLa whole cell lysate (+).
Lane 3: Rabbit monoclonal IgG (ab172730) instead of ab218230 in HeLa whole cell lysate (-).

Blocking/Dilution buffer and concentration: 5% NFDM/TBST.
Exposure time: 3 minutes.
