You will receive 1 vial of lysate (100ug), 1 vial of empty vector negative control (100ug), and 1 vial of 2xSDS sample buffer (250ul). Each vial of cell lysate contains 100ug of total protein (at 1 mg/ml). The 2xSDS Sample Buffer consists of 4% SDS, 125mM Tris-HCl pH6.8, 10% Glycerol, 0.002% Bromophenol blue, 100mM DTT.

Application Notes

This product is intended for use as a positive control in Western Blot. Overexpression of the target protein was confirmed using an antibody to DDK (FLAG) epitope tag (NBP1-71705) present on the protein construct.

Each vial of cell lysate contains 100ug of total protein which should be sufficient for 20-50 reactions. Depending on over-expression level, antibody affinity and detection system, some lysates can go as low as 0.1 ug per load. We recommend starting with 5ug of cell lysate. Add an equal amount of cell lysate and 2X SDS Sample buffer and boil the SDS samples for 10 minutes before loading.

TMW

56.8 kDa.
Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

Background: FRS2

FGFs (Fibroblast Growth Factors) bind to FGF receptors (FGFRs) monovalently, and FGF receptor dimerization and activation is mediated by multivalent interactions between heparin sulfate proteoglycans and FGF. Upon activation, receptor tyrosine kinases undergo rapid autophosphorylation on numerous tyrosine residues. Autophosphorylation sites located within the catalytic domain are crucial for stimulation of kinase activity, while autophosphorylation sites located in other regions are usually involved in the recruitment of cellular target proteins. Fibroblast growth factor or nerve growth factor (NGF) stimulation leads to tyrosine phosphorylation of the FGF Receptor Substrate 2 (FRS2) docking proteins. FRS2 is also designated SNT (Suc-1 associated neurotrophic factor target protein). Two structurally similar forms of FRS2 are: FRS2a (SNT-1) and FRS-2b (SNT-2, FRS3). FRS functions as a lipid-anchored docking protein that is tyrosine phosphorylated and recruited to FGFR upon FGF stimulation. FRS2 plays an important role in linking FGF and NGF with the Ras/MAPK signaling pathway, thus relaying information from the cell surface to the nucleus. FRS2 contains both a consensus myristylation sequence, involved in its recruitment to the cell membrane and a putative phosphotyrosine binding (PTB)domain in its amino-terminus. The interaction of FRS2 with FGFR1 occurs via the PTB domain of FRS2 binding to a 12-residue segment in the juxtamembrane region of FGFR1. FRS2a contains four binding sites for the adaptor protein Grb2 and two binding sites for the protein tyrosine phosphatase Shp2. FGF stimulation leads to phosphorylation of Shp2 on a tyrosine residue forming a complex with an additional molecule of Grb2. Grb2/Sos complexes are thus recruited directly and indirectly via Shp2 upon tyrosine phosphorylation of FRS2a in response to growth factor stimulation. It has been shown that FRS2 proteins are tyrosine phos phorylated in response to activation of the RET receptor, a tyrosine kinase that functions as the signal transducing receptor for the GDNF.

Product Specific Notices for FRS2 Overexpression Lysate

HEK293T cells in 10-cm dishes were transiently transfected with a non-lipid polymer transfection reagent specially designed and manufactured for large volume DNA transfection. Transfected cells were cultured for 48hrs before collection. The cells were lysed in modified RIPA buffer (25mM Tris-HCl pH7.6, 150mM NaCl, 1% NP-40, 1mM EDTA, 1xProteinase inhibitor cocktail mix, 1mM PMSF and 1mM Na3VO4, and then centrifuged to clarify the lysate. Protein concentration was measured by BCA protein assay kit.

This product is for research use only and is not approved for use in humans or in clinical diagnosis. Lysates are guaranteed for 6 months from date of receipt.
