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 Daudi human Burkitt's lymphoma cell line and Ramos human Burkitt's lymphoma cell lines. PVDF membrane was probed with 0.3 µg/mL of Goat Anti-Human Lyp Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3428) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). 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 PBMCs by Immunocytochemistry (ICC).

Lyp in Human PBMCs.

Lyp was detected in immersion fixed human peripheral blood mononuclear cells (PBMCs) using Goat Anti-Human Lyp Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3428) at 15 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI (blue). Specific staining was localized to cytoplasmic. View our protocol for Fluorescent ICC Staining of Non-adherent Cells.
Detection of Human Lyp antibody by Simple WesternTM.

Detection of Human Lyp by Simple WesternTM.

Simple Western lane view shows lysates of Daudi human Burkitt's lymphoma cell line and Ramos human Burkitt's lymphoma cell line, loaded at 0.2 mg/mL. A specific band was detected for Lyp at approximately 116-118 kDa (as indicated) using 3 µg/mL of Goat Anti-Human Lyp Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3428) followed by 1:50 dilution of HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

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
