Biological Information

Background Information:

Fibroblast growth factor (FGF) superfamily consists of 23 members, all of which contain a conserved 120 amino acid (aa) core region that contains six identical, interspersed amino acids. Based on the pI factor, two main groups of FGF are named: acidic FGF (aFGF) and basic FGF (bFGF). The superfamily members act extracellularly through four tyrosine kinase FGF receptors (FGFR1 through FGFR4), with multiple specificities noted for almost all FGFs. Biological binding of aFGF to its receptors will result in phosphorylation of the receptor and non-receptor proteins and generate its function. Overexpression and amplification of the fibroblast growth factor receptor-1 (FGFR-1), a prototypic receptor tyrosine kinase, have been found in tumor samples from human pancreas, breast, brain, prostate, thyroid gland, and salivary gland.

Testing Information

Procedure Summary:

FGFR1 (h) is incubated with 8 mM MOPS pH 7.0, 0.2 mM EDTA, 250 µM KKKSPGEYVNIEFG, 10 mM MgAcetate and [gamma-33P]-ATP (specific activity and concentration as required). The reaction is initiated by the addition of the Mg/ATP mix. After incubation for 40 minutes at room temperature, the reaction is stopped by the addition of phosphoric acid to a concentration of 0.5%. An aliquot of the reaction is then spotted onto a filter and washed four times for 4 minutes in 0.425% phosphoric acid and once in methanol prior to drying and scintillation counting.

Substrate:

250 µM KKKSPGEYVNIEFG

Tracer:

33P

ATP Concentration:

[ATP]= 10µM (Km= 369µM )

Incubation:

40 min at Room temperature

Control Inhibitor:

Staurosporine

Test Sample Requirements:

Please provide compounds dissolved in 100% DMSO (PBS or HBSS prohibited).
Stock solution should be ≥50× the final assay concentration (a 10 mM stock is also acceptable).
Required volume:
– <60 kinase assays: 120 µL of 50× stock
– ≥60 assays: 420 µL of 50× stock
If you supply 10 mM stocks or powder (pre-weighed), we will apply the appropriate conversion.
For batches of ~50 compounds supplied as solids, the TAT will be extended.
