Products from BPS Bioscience require a minimum order value above 400€
Encompassing Amino Acids: 1-836
Applications: Useful for studying enzyme kinetics and screening small molecule inhibitors.
Assay Conditions: 10 µl of varying amounts of PLK4 was mixed with 5 µl of 1 mg/ml MBP protein substrate and 5 µl of distilled water. Reaction was initiated by adding 5 µl of 250 µM [33P]-ATP and incubating for 15 min at 30°C followed by spotting the reaction on phosphocellulose paper, fixing in 1% phosphoric acid, and assaying with a scintillation counter.
