- Extra Details:
- MaxLight™ 490 is a new Blue-Green photostable dye conjugate comparable to DyLight™488, Alexa Fluor™488 and offers better labeling efficiency, brighter imaging and increased immunodetection. Absorbance (491nm); Emission (515nm); Extinction Coefficient 73,000. Epidermal growth factor (EGF) receptor is a 170kD tyrosine kinase. Ligand binding results in receptor dimerization, autophosphorylation, activation of downstream signaling and lysosomal degradation. Phosphorylation of Tyr845 in the kinase domain is implicated in stabilizing the activation loop, maintaining the enzyme in an active state and providing a binding surface for substrate proteins. c-Src is involved in phosphorylation of Tyr845. Phospho-tyrosine 992 is a direct binding site for the PLC gamma SH2 domain, resulting in activation of PLC gamma-mediated downstream signaling. Phosphorylation of Tyr1045 creates a major docking site for c-Cbl. Binding of c-Cbl to the activated EGFR leads to receptor ubiquitination and degradation. Phospho-Tyr1068 of activated EGFR is a direct binding site for Grb2. Phospho-tyrosine 1148 and 1173 provide a docking site for SHC. Both sites are involved in the activation of MAP kinase signaling. Phosphorylation of EGFR on serine and threonine residues attenuates EGFR kinase activity. Serines 1046 and 1047 in the carboxy-terminal region of EGFR are sites phosphorylated by CaM kinase II. Mutations to either serine 1046 or 1047 upregulate tyrosine autokinase activity of EGFR. Applications: Suitable for use in FLISA, Western Blot, Immunoprecipitation, Immunohistochemistry, Immunocytochemistry and Immunofluorescence. Other applications have not been tested. Recommended Dilutions: Immunocytochemistry: Formalin-fixed cells Immunohistochemistry: Paraffin sections Optimal dilutions to be determined by the researcher. Recommended Positive Control: A-431 cells Storage and Stability: Store product at 4°C in the dark. DO NOT FREEZE! Stable at 4°C for 12 months after receipt as an undiluted liquid. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer. Caution: MaxLight™490 conjugates are sensitive to light. For maximum recovery of product, centrifuge the original vial prior to removing the cap. Note: Applications are based on unconjugated antibody.
