A_W20038C_PURE_CRK_Antibody_WB_112222
Whole cell extracts (15 µg total protein) from the indicated cell lines were resolved by 4-12% Bis-Tris gel electrophoresis, transferred to a PVDF membrane, and probed with 0.1 µg/mL of purified anti-CRK (clone W20038C) overnight at 4°C. Proteins were visualized by chemiluminescence detection using HRP goat anti-rat IgG (Cat. No. 405405) at a 1:3000 dilution. Direct-Blot™ HRP anti-β-actin (Cat. No. 664804) was used as a loading control at a 1:25000 dilution. Lane M: Molecular weight marker

  • B_W20038C_PURE_CRK_Antibody_IHC_112222
    IHC staining of purified anti-CRK (clone W20038C) on formalin-fixed paraffin-embedded human liver tissue. Following antigen retrieval using Tris-buffered saline with Tween-20 (Cat. No. 925501), the tissue was incubated with 5.0 µg/mL of the primary antibody overnight at 4°C, followed by incubation with Alexa Fluor® 647 goat anti-rat IgG (Cat. No. 405416) for one hour at room temperature. Nuclei were counterstained with DAPI and the slides were mounted with ProLong™ Gold Antifade Mountant. The image was captured with a 40X objective.

    HepG2 cells were fixed with ice-cold methanol for 10 minutes and blocked with 5% FBS for 60 minutes. Cells were then intracellularly stained with 5.0 µg/mL of either purified rat IgG2a, κ isotype control (Cat. No. 400502) (panel A) or purified anti-CRK (clone W20038C) (panel B) overnight at 4°C, followed by incubation with Alexa Fluor® 594 goat anti-rat IgG (Cat. No. 405422) at 2.0 µg/mL. Nuclei were counterstained with DAPI and the image was captured with a 60X objective. Scale bar: 50 µm

Description

Adapter protein CRK, also known as CRK proto-oncogene adaptor protein or V-CRK avian sarcoma virus CT10 oncogene homolog, has two isoforms: CRKI (28 kD) and CRKII (40 kD). Closely associated is CRKL, or CRK-like protein (36 kD). CRKII and CRKL possess a C-terminal SH3 domain and a regulatory tyrosine phosphorylation site that are lacking in CRKI. CRK’s SH2 and SH3 domains serve as positive and negative regulators of transformation, respectively. CRK is vital to cell motility via activation of Rac1 by CRKII and CRKL and cell branching and adhesion via activation of Rap1 by CRKI. It is also vital to cell proliferation, apoptosis, formation and turnover of focal adhesions, PDGF-induced actin cytoskeleton rearrangement, cell migration, and transcription. Overexpressed in several cancers, CRK has been implicated in tumor proliferation, metastasis, and resistance to chemotherapy. This, in addition to its roles in natural killer cell activation and differentiation, lymphocyte regulation, B cell signaling, and T cell migration, makes CRK a valuable therapeutic target.

Application

WB - Quality tested
IHC-P, ICC - Verified
Recommended Usage

Each lot of this antibody is quality control tested by western blotting. For western blotting, the suggested use of this reagent is 0.1 µg/mL. For immunohistochemistry on formalin-fixed paraffin-embedded tissue sections, a concentration range of 1.0 - 10.0 µg/mL is suggested. For immunocytochemistry, a concentration range of 1.25 - 5.0 μg/mL is recommended. It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes

When testing by ICC, methanol rather than PFA fixation is recommended.

Clone W20038C is not recommended for immunoprecipitation.
