Scientific Data Images for Human Lyp Antibody

Detection of Human Lyp antibody by Western Blot.

Detection of Human Lyp by Western Blot.

Western blot shows lysates of Jurkat human acute T cell leukemia cell line, Daudi human Burkitt's lymphoma cell line, and Ramos human Burkitt's lymphoma cell line. PVDF membrane was probed with 1 µg/mL of Mouse Anti-Human Lyp Monoclonal Antibody (Catalog # MAB3428) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for Lyp at approximately 108 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Lyp antibody in Human Lymph Node by Immunohistochemistry (IHC-P).

Lyp in Human Lymph Node.

Lyp was detected in immersion fixed paraffin-embedded sections of human lymph node using 25 µg/mL Mouse Anti-Human Lyp Monoclonal Antibody (Catalog # MAB3428) overnight at 4 °C. Tissue was stained with the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counterstained with hematoxylin (blue).

Detection of Lyp by Western Blot

Lyp protein expression in Jurkat T cells 72 hours after the beginning of O/N transfection with different doses of siRNA s/a in DMPC/1/siRNA lipoplexes.Representative duplicate experiment among all replicas in S4 Fig. (A) Lyp expression in Jurkat T cells after O/N transfection with DMPC/1 alone (DMPC/1), 20 pmols of siRNA alone (siRNA20) and 20 pmols of siRNA complexed with DMPC/1 (DMPC/1/siRNA20) or cultured in RPMI. 20 pmols of siRNA complexed with DMPC/1 resulted in a 15% reduction of Lyp expression. (B) Same experiment as in A using 60 pmols of siRNA (siRNA60) complexed with DMPC/1 (DMPC/1/siRNA60). 33% reduction of Lyp expression was obtained. (C) Same experiment as in A using 100 pmols of siRNA (siRNA100) complexed with DMPC/1 (DMPC/1/siRNA100). 45% reduction of Lyp expression was obtained. (D) Representative WB image within all experimental groups is shown.

Detection of Lyp by Western Blot

Lyp protein levels in Jurkat T cells 48 hours after the beginning of O/N transfection with different doses of siRNA s/a in DMPC/1/siRNA lipoplexes.Representative duplicate experiment among all replicas in S4 Fig. (A) Lyp expression in Jurkat T cells cultured in RPMI or after O/N transfection with DMPC/1, 20 pmols of siRNA and 20 pmols of siRNA in DMPC/1/siRNA lipoplexes (DMPC/1/siRNA20). 20 pmols of siRNA complexed with DMPC/1 resulted in a 31% reduction of Lyp expression. (B) Same experiment as in A using 60 pmols of siRNA complexed with DMPC/1 (DMPC/1/siRNA60). 39% reduction of Lyp expression was obtained. (C) Same experiment as in A using 100 pmols of siRNA complexed with DMPC/1 lipoplexes (DMPC/1/siRNA100). 47% reduction of Lyp expression was obtained. (D) Representative WB image within all experimental groups is shown. Under each blot Lyp O.D. values for every treatment are normalized over the corresponding beta -actin values. All percentages were expressed relatively to untransfected cells (RPMI) that is considered the 100% of basal Lyp expression. Graphs A, B, C show the mean values and their standard deviations. In all experimental conditions (vide infra), a decrease in Lyp protein level was not observed in cells treated with the liposome alone or, more importantly, in cells treated with the correspondent dose of the siRNA s/a free molecule.

Background: Lyp

Lymphoid phosphatase (Lyp), also called LyPTP, Protein Tyrosine Phosphatase, Nonreceptor-type 22 (PTPN22), and PEST-domain Phosphatase (PEP), dephosphorylates tyrosine residues in proteins. Found primarily in bone marrow and lymphoid cell lines, an R620W gain-of-function mutation in Lyp has been associated with susceptibility to autoimmune diseases such as type I diabetes, rheumatoid arthritis, and lupus erythematosus. Mature PEP knockout mice have an excess of CD8 positive T cells and an exaggerated antigen-induced proliferative response.

Long Name

Lymphoid Phosphatase

Alternate Names

LyPTP, PEP, PTPN22, PTPN8 (former)
