- Description
- Western blot analysis of MA1-153 detects ~130-160 kDa and a 210-250 kDa protein in K562 cells. In addition to BCR-ABL, BCR and ABL are also expressed in these cells and full length BCR is also detected by the antibody. For detection purposes, non-reducing conditions resulted in enhanced detection of BCR-ABL.

- Western blot analysis of BCR-ABL and BCR was performed following immunoprecipitation from K562 cell lysates using a phosphotyrosine monoclonal antibody for immune complex capture, and a BCR antibody (Product # MA1-153) for Western Blot detection. Immunoprecipitated proteins from 500 µg whole cell lysate and 10 µl of PageRuler Prestained Protein Ladder (Product # 26616) were resolved on a 4-20% Tris-HCl polyacrylamide gel, transferred to a PVDF membrane, and blocked with 5% BSA/TBST for at least 1 hour. The membrane was probed with a BCR monoclonal antibody (Product # MA1-153) at a dilution of 1:1000 overnight rotating at 4°C, washed in TBST, and probed with a goat anti-mouse IgG-HRP secondary antibody (Product # 31430) at a dilution of 1:20,000 for 1 hour. Chemiluminescent detection was performed using SuperSignal West Pico (Product # 34080). Note: Best results were obtained using non-reducing LDS sample buffer in SDS-polyacrylamide gel electrophoresis (Product # 84788).

- Knockout of BCR was achieved by CRISPR-Cas9 genome editing using LentiArray™ Lentiviral sgRNA (Product # A32042, Assay ID CRISPR981967_LV) and LentiArray Cas9 Lentivirus (Product # A32064). Western blot analysis of BCR was performed by loading 30 µg of A-431 Wild Type (Lane 1), A-431 Cas9 (Lane 2) andA-431 BCR KO (Lane 3) whole cell extracts. The samples were electrophoresed using NuPAGE™ 3-8% Tris-Acetate Protein Gel (Product # EA0378BOX). Resolved proteins were then transferred onto a nitrocellulose membrane (Product # IB23001) by iBlot® 2 Dry Blotting System (Product # IB21001). The blot was probed with Anti-BCR-ABL Monoclonal Antibody (7C6) (Product # MA1-153, 1:1,000 dilution) and Goat anti-Mouse IgG (H+L) Superclonal™ Recombinant Secondary Antibody, HRP (Product # A28177, 1:5,000 dilution) using the iBright FL 1000 (Product # A32752). Chemiluminescent detection was performed using Novex® ECL Chemiluminescent Substrate Reagent Kit (Product # WP20005). Loss of signal upon CRISPR mediated knockout (KO) using the LentiArray™ CRISPR product line confirms that antibody is specific to BCR.

- Western blot analysis was performed on membrane enriched extracts of K-562 (Lane 1), AML-193 (Lane 2), Jurkat (Lane 3) and Hep G2 (Lane 4). The blot was probed with Anti-BCR-ABL Monoclonal Antibody (Product # MA1-153, 1:1000 dilution) and detected by chemiluminescence using Goat anti-Mouse IgG (H+L) Superclonal™ Secondary Antibody, HRP conjugate (Product # A28177, 0.25 µg/ml, 1:4000 dilution). A 210 kDa band corresponding to BCR-ABL was detected in K-562 cell line when compared to other cell lines which were reported to be negative. Also the antibody detects 130, 160 kDa band corresponding to BCR across all the cell lines tested.

- Immunofluorescent analysis of BCR-ABL (green) in K562 cells. Formalin fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 10 minutes at room temperature. Cells were blocked with 1% Blocker BSA (Product # 37525) for 15 minutes at room temperature. Cells were probed with a BCR-ABL monoclonal antibody (Product # MA1-153) at a dilution of 1:50 for at least 1 hour at room temperature, washed with PBS, and incubated with a DyLight 488-conjugated goat anti-mouse IgG secondary antibody (Product # 35502). Nuclei (blue) were stained with Hoechst 33342 dye (Product # 62249). Images were taken on a Thermo Scientific ToxInsight Instrument at 20X magnification.

- Immunofluorescence analysis of BCR-ABL was performed using 70% confluent log phase K-562 cells. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 15 minutes, and blocked with 1% BSA for 1 hour at room temperature. The cells were labeled with BCR-ABL Monoclonal Antibody (7C6) (Product # MA1-153) at 1:100 dilution in 0.1% BSA, incubated at 4 degree Celsius overnight and then labeled with Goat anti-Mouse IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (Product # A28175) at a dilution of 1:2000 for 45 minutes at room temperature (Panel a: green). Nuclei (Panel b: blue) were stained with ProLong™ Diamond Antifade Mountant with DAPI (Product # P36962). F-actin (Panel c: red) was stained with Rhodamine Phalloidin (Product # R415). Panel d represents the merged image showing membranous localization. Panel e represents control cells with no primary antibody to assess background. The images were captured at 60X magnification.

- Immunohistochemistry analysis of BCR-ABL showing staining in the nucleus of paraffin-embedded human breast carcinoma (right) compared with a negative control without primary antibody (left). To expose target proteins, antigen retrieval was performed using 10mM sodium citrate (pH 6.0), microwaved for 8-15 min. Following antigen retrieval, tissues were blocked in 3% H2O2-methanol for 15 min at room temperature, washed with ddH2O and PBS, and then probed with a BCR-ABL monoclonal antibody (Product # MA1-153) diluted in 3% BSA-PBS at a dilution of 1:200 overnight at 4°C in a humidified chamber. Tissues were washed extensively in PBST and detection was performed using an HRP-conjugated secondary antibody followed by colorimetric detection using a DAB kit. Tissues were counterstained with hematoxylin and dehydrated with ethanol and xylene to prep for mounting.

- Immunoprecipitation of BCR-ABL and BCR was performed using K562 whole cell lysate. Antigen-antibody complexes were formed by incubating 800 µg of lysate with 5 µg of a BCR monoclonal antibody (Product # MA1-153) overnight on a rocking platform at 4øC. The immune complexes were captured on 50 µl Protein A/G Agarose (Product # 20421), washed extensively, and eluted with 5X Lane Marker Reducing Sample Buffer (Product # 39000). The sample was resolved on a 4-20% Tris-HCl polyacrylamide gel, transferred to a PVDF membrane, and blocked with 5% BSA/TBS-0.1%Tween for 1 hour. The membrane was probed with a phosphotyrosine monoclonal antibody (detecting p-Tyr-BCR-ABL/p-Tyr-BCR) at a dilution of 1:1000 overnight rotating at 4øC, washed in TBST, and probed with a goat anti-mouse IgG-HRP secondary antibody (Product # 31430) at a dilution of 1:20,000 for 1 hour. Chemiluminescent detection was performed using SuperSignal West Pico (Product # 34080).
