Tested Applications

• Positive WB detected in: HeLa cells, mouse brain tissue
• Positive IP detected in: mouse brain tissue
• Positive IHC detected in: human kidney 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 : 1:500-1:1000
• Immunoprecipitation (IP): IP : 0.5-4.0 ug for 1.0-3.0 mg of total protein lysate
• Immunohistochemistry (IHC): IHC : 1:50-1:500

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

Background Information

Type II a receptor protein tyrosine phosphatases (rPTPσ) are cell surface receptors important for nervous system development, function, and repair.The expression of rPTPσ has previously been reported in b-cells and other target organs for INS although the probes chosen did not permit to distinguish between the splice variants.Proteolytic processing near the transmembrane domain generates an extracellular N-terminal E-domain of 130 kDa and a C-terminal P-domain of approximately 85 kDa of rPTPσ,and the short splice variants rPTPσ 3 and 4 contain an E-domain of 95 kDa (PMID: 16552719). rPTPσ expression was observed in tissue lysates of the adult mouse sensory-motor cortex and thoracic spinal cord (T8-T10) as a 75-80kDa immunoreactive band (PMID: 19780196).
