Tested Applications

• Positive WB detected in: HEK-293 cells
• Positive IP detected in: HEK-293 cells
• Positive IHC detected in: human spleen tissue; Note: suggested antigen retrieval with TE buffer pH 9.0; (*) Alternatively, antigen retrieval may be performed with citrate buffer pH 6.0

Recommended dilution

• Western Blot (WB): WB : 1:500-1:2000
• Immunoprecipitation (IP): IP : 0.5-4.0 ug for 1.0-3.0 mg of total protein lysate
• Immunohistochemistry (IHC): IHC : 1:20-1:200

It is recommended that this reagent should be titrated in each testing system to obtain optimal results.

Background Information

SYK(spleen tyrosine kinase) is a key regulator of signal transduction events,apoptosis and orderly cell cycle progression in B-lineage lymphoid cells. Although SYK has not been linked to a human disease, defective expression of the closely related T-cell tyrosine kinase ZAP-70 has been associated with severe combined immunodeficiency(PMID:11494125). This protein has 2 isoforms produced by alternative splicing. SYK also promotes liver fibrosis by activation of hepatic stellate cells and acts as a biomarker for human hepatocellular carcinoma.
