50042
Fluorogenic HDAC class 2a substrate 2 (green)
BPS Bioscience
DESCRIPTION
A fluorogenic, acetylated peptide substrate for class2a HDACs (HDACs 4, 5, 7 and 9). It also works well for HDACs 8 and 11. This substrate exhibits longer excitation and emission wavelengths (excitation 485 nm, emission 528 nm) than our regular class 2a HDAC substrate, #50040, which fluoresces at excitation 350-380 nm, emission at 440-460 nm. This substrate should be used when the inhibitor fluoresces near 450 nm. If autofluorescence is not an issue, we recommend product #50040. For autofluorescent samples using HDACs 1-3 ,6, and 10, we recommend substrate #50038.

- Instructions for Use: Materials : HDAC Assay buffer (BPS catalog #50031) HDAC Assay developer (BPS catalog #50030) HDAC Class 2A Substrate 2 (green) (catalog #50042)HDAC4 (0.2 ng/µl) (BPS catalog #50004) or other class2a HDAC enzyme Step 1 : Add the following reagents to a low binding NUNC black plate (VWR catalog #62408-936): HDAC Assay Buffer, 35 µl1 mg/ml BSA, 5 µl 200 µM HDAC 2A substrate 2, 5 µlHDAC4, 5 µl Incubate at 37°C for 30 min. Step 2 : Stop the reaction by adding 50 µl of HDAC assay developer (undiluted) and incubate the plate at room temperature for 15 min. Step 3 : Read samples in a microtiter-plate reading fluorimeter capable of excitation at 485 nm and emission at 528 nm. "Blank" value (no enzyme negative control) is subtracted from all other values.
