W17240D_Pure_SHP-1_Antibody_1_061819
Whole cell extracts (15 µg protein) from SH-SY5Y and U87-MG (negative control), MOLT-4, Jurkat, THP-1, and EL4 cells were resolved by 4-12% Bis-Tris gel electrophoresis, transferred to a PVDF membrane, and probed with 0.1 µg/mL (1:5000 dilution) of Purified anti-SHP-1 Antibody, clone W17240D, overnight at 4°C. Proteins were visualized by chemiluminescence detection using HRP goat anti-rat IgG Antibody (Cat. No. 405405) at a 1:3000 dilution. Direct-Blot™ HRP anti-GAPDH Antibody (Cat. No. 607904) was used as a loading control at a 1:25000 dilution (lower). Lane M: Molecular Weight marker. Predicted expression data was obtained from Human Protein Atlas.

    Jurkat cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with ice-cold methanol for 10 minutes, and blocked with 5% FBS for 60 minutes. Cells were then intracellularly stained with a 1:100 dilution (5.0 µg/mL) of either Purified Rat IgG2b, κ Isotype Control Antibody (Cat. No. 400602, panel A) or Purified anti-SHP-1 Antibody, clone W17240D (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 counter-stained with DAPI, and the image was captured with a 60X objective.

    Whole cell extracts (250 µg total protein) prepared from Jurkat cells were immunoprecipitated overnight with 2.5 µg of Purified rat IgG2b, κ Isotype Control Antibody (Cat. No. 400602) or Purified anti-SHP-1 Antibody, clone W17240D. The resulting IP fractions and whole cell extract input (5%) were resolved by 4-12% Bis-Tris gel electrophoresis, transferred to a PVDF membrane, and probed with a 1.0 µg/mL (1:500 dilution) of W17240D.

Description

SHP-1, also referred to as PTPN6 is an inhibitory protein phosphatase widely expressed in hematopoietic cell lineages that regulates cell cycle, proliferation, and inflammatory pathways. SHP-1 dephosphorylates activating signaling molecules in receptor tyrosine kinase pathways; in T cells it functions as a negative regulator of T cell activation and proliferation. SHP-1 is constitutively bound to the ITIM-containing adaptor molecules such as the inhibitory receptor LAIR-1; activation of SHP-1 results in either direct dephosphorylation of the T cell receptor or downstream effector molecules such as Zap70 and Lck. Reduced expression of SHP1 is found in leukemias, lymphomas, and colorectal cancers due to promoter hypermethylation of the PTPN6 gene.

Product Details

Reactivity
Human
Antibody Type
Monoclonal
Host Species
Rat
Immunogen
Partial recombinant protein corresponding to amino acid residues 1-213 of human SHP-1
Formulation
Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide.
Preparation
The antibody was purified by affinity chromatography.
Concentration
0.5 mg/ml
Storage & Handling
The antibody solution should be stored undiluted between 2°C and 8°C.
Application

WB - Quality tested
ICC, IP - Validated

Recommended Usage

Each lot of this antibody is quality control tested by Western blotting. For Western blotting, the suggested use of this reagent is 0.25 - 1.0 µg per ml. For immunocytochemistry, a concentration range of 1.0 - 5.0 μg/ml is recommended. For immunoprecipitation, the suggested use of this reagent is 2.5 µg per ml. It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes

W17240D was tested for ICC using PFA-fixed Jurkat cells permeabilized with either Triton X-100 or methanol. While both permeabilization methods facilitated SHP-1 staining, methanol resulted in considerably stronger staining.
