Product Specific Information
This monoclonal antibody is highly purified and conjugated to agarose (4% cross-linked).
Supplied as 0.5 mL of settled gel in 1 mL of 50% suspension containing:
- 10 mM PBS (pH 7.0)
- 100 mM NaCl
- 0.1% Proclin
This antibody is known to show reactivity towards phosphothreonine.
Target Information
Tyrosine phosphorylation plays a critical role in mitogenic signal transduction from transmembrane receptors and in transformation by oncogene tyrosine kinases.
Phosphorylation of specific tyrosine residues is a primary mechanism of:
- Signal transduction during normal mitogenesis
- Cell cycle progression
- Oncogenic transformation
Its role in differentiation and gap junction communication remains under active investigation.
Antibodies recognizing phosphorylated tyrosine residues are essential tools for studying tyrosine-phosphorylated proteins and related biochemical pathways.
The fluorescein (FITC) conjugate of clone PY20 anti-phosphotyrosine is particularly useful for detecting P-Tyr proteins in immunohistochemical and immunocytochemical protocols, especially where secondary antibody use may complicate detection.
For Research Use Only. Not for use in diagnostic procedures. Not for resale without express authorization.
