Biological Activity

Description 740 Y-P (PDGFR 740Y-P, 740YPDGFR) is cell-permeable phosphopeptide activator of PI3K.
Targets
PI3K [1]
In vitro

The PDGFR 740Y-P peptide stimulates a mitogenic response in muscle cells. The ability of the 740Y-P peptide to stimulate mitogenesis is highly specific and not a general feature of a cell permeable SH2 domain binding peptides[2]. 740Y-P is as effective as a growth factor (FGF2) at promoting neuronal cell survival via the established PI 3-kinase-Akt survival cascade. Stimulation of neuronal cell survival by the PDGFR740Y-P peptide is dose dependent and does not require insulin[1].

Protocol (from reference)

Cell Research:

[2]

  • Cell lines: NIH 3T3 cells
  • Concentrations: 50 μg/ml
  • Incubation Time: 2 h
  • Method:

    NIH 3T3 cells (2×106) are incubated in suspension at 37°C in Ca2+ and Mn2+ free HBSS, 10% FCS containing either 50 μg/ml of 740Y-P peptide or an equal volume of PBS as a control. After 2h cells are centrifuged, washed and trypsinised to degrade non-internalised peptide. Cells are then resuspended in lysis buffer (50 mM Tris pH 7.4, 150 mM NaCl, 10% Glycerol, 2% NP40, 0.25% deoxycholate, 1 mM EDTA, 1 mM Vanadate, Protease inhibitors "complete" cocktail from Boehringer-Mannheim) for 1 h at 4°C. Lysates are clarified by centrifugation at 1.4×104g for 5 min and the supernatants are incubated for 1h with streptavidin-agarose beads. Beads are subsequently washed three times in lysis buffer and finally boiled in SDS sample buffer and resolved by SDS-PAGE on a 12% gel, transferred to nitrocellulose and immunoblotted with the p85 monoclonal antibody.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
