Non-receptor type 22 protein tyrosine phosphatase (PTPN22) polyclonal antibody
Cat. No. Format Size Price
PAB-10785 Purified 100 µg 275 Euro
Animal ID: 
Purified rabbit polyclonal antibody supplied in PBS with 0.09% (W/V) sodium azide. This antibody is purified through a protein G column and eluted out with both high and low pH buffers and neutralized immediately after elution then followed by dialysis against PBS. 
Maintain refrigerated at 2-8ºC for up to 6 months. For long term storage store at -20ºC. Avoid repeated freeze-thaw cycles. 
Tested by peptide-specific ELISA (1:1,000). 
KLH conjugated synthetic peptide comprised of amino acids 311 - 325 [CIPEKNHTLQADSYS] of the human non-receptor type 22 protein tyrosine phosphatase (PTPN22) protein. 
Accession number:
Following activation of T cells, phosphorylation of tyrosine residues occurs through a complex signaling process involving protein tyrosine kinases, phosphatases, and a variety of adapter molecules including Grb2. The non-receptor type 22 protein tyrosine phosphatase (PTPN22) is an enzyme which associates with the molecular adapter protein CBL and may be involved in regulating CBL function in the T-cell receptor signaling pathway. PTPN22 contains three SH3 domains and a PTB domain binding motif, and it is primarily expressed in lymphoid tissues.
Alternative Name(s):
LYP, Lyp, Lyp1, Lyp2, protein tyrosine phosphatase homolog, lymphoid-specific protein tyrosine phosphatase
