Unknown

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Slit2 antibody [EPR2771] - BSA and Azide free (AB240085)

Immunohistochemical analysis of paraffin embedded Human fetal kidney tissue labelled with ab134166 at 1/100 dilution.

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab134166).

Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.

Western blot - Anti-Slit2 antibody [EPR2771] - BSA and Azide free (AB240085)

Blocking buffer and concentration :  5% NFDM/TBST  Diluting buffer and concentration :  5% NFDM/TBST The expression level of Slit2 in T-47D and A549 are consistent with describes in PMID : 24287947 and PMID : 12384551. Negative control : T-47D and A549 (PMID : 24287947 and PMID : 12384551). Slit2 is a secretory protein, so Brefeldin A (BFA) would help to increase the detection of Slit2 in cell lysate. ab181602 was used as a loading control. This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab134166).

Western blot - Anti-Slit2 antibody [EPR2771] - BSA and Azide free (AB240085)

This data was developed using ab134166, the same antibody clone in a different buffer formulation.

ab134166 was shown to react with SLIT2 in wild-type HAP1 cells in Western blot with loss of signal observed in a SLIT2 knockout cell line. Wild-type HAP1 and SLIT2 knockout cell lysates were subjected to SDS-PAGE. Membranes were blocked in 5% milk in TBST for 1 hr before incubation with ab134166 overnight at 4 °C at a 1/1000 dilution. Blots were incubated with secondary antibodies at 0.2 µg/mL before imaging.

These data were provided by YCharOS Inc., an open science company with the mission of characterizing commercially available antibody reagents for all human proteins. Abcam and YCharOS are working together to help address the reproducibility crisis by enabling the life science community to better evaluate commercially available antibodies.
