PTP1B Antibody (YA1776)

PTP1B Antibody (YA1776) is a Rabbit-derived and non-conjugated IgG monoclonal antibody, targeting to PTP1B.

The protein encoded by The related gene is the founding member of the protein tyrosine phosphatase (PTP) family, which was isolated and identified based on its enzymatic activity and amino acid sequence. PTPs catalyze the hydrolysis of the phosphate monoesters specifically on tyrosine residues. Members of the PTP family share a highly conserved catalytic motif, which is essential for the catalytic activity. PTPs are known to be signaling molecules that regulate a variety of cellular processes including cell growth, differentiation, mitotic cycle, and oncogenic transformation. The PTP has been shown to act as a negative regulator of insulin signaling by dephosphorylating the phosphotryosine residues of insulin receptor kinase. The PTP was also reported to dephosphorylate epidermal growth factor receptor kinase, as well as JAK2 and TYK2 kinases, which implicated the role of The PTP in cell growth control, and cell response to interferon stimulation. Two transcript variants encoding different isoforms have been found for The related gene.

• 
  Western blot analysis of extracts from HepG2 (lane 2(20μg) , Hela (lane 3(20μg) , A431 (lane 4(20μg),using PTP1B Antibody. Proteins were transferred to a PVDF membrane and blocked with 5% BSA in TBST for 2 hour at room temperature. The primary antibody and Loading control antibody (Beta Actin, HY-P80438, 1/3000) was used in 5% BSA in TBST at 4°C overnight. Goat Anti-Mouse/Rabbit IgG-HRP Secondary Antibody (HY-P8004/HY-P8001, 1/10,000) was used for 1 hour at room temperature.
• 
  Immunocytochemistry analysis of Hela cells labeling PTP1B with PTP1B Antibody (HY-P82031) at 1/50 dilution. Cells were fixed in 4% paraformaldehyde for 15 minutes at room temperature, permeabilized with 0.1% Triton X-100 for 10 minutes at room temperature, then blocked with QuickBlock™ Blocking Buffer for Immunol Staining for 10 min at room temperature. Cells were then incubated with PTP1B Antibody (HY-P82031) at 1/50 dilution in QuickBlock™ Blocking Buffer for Immunol Staining at 4 ℃. Alexa Fluor® 594-conjugated AffiniPure Goat Anti-Rabbit IgG H&L（HY-P8003, Green) was used as the secondary antibody at 1/1,000 dilution. PBS instead of the primary antibody was used as the secondary antibody only control. The Nuclear counterstain was DAPI (Blue).
