Fluorogenic HDAC substrate 1

Catalog #: 50032
Size: 500 nmole
A fluorogenic, acetylated peptide substrate for HDAC2, HDAC3, and HDAC6 (tested so far). This substrate fluoresces at excitation 350-380 nm, emission at 440-460 nm. It should be used in conjunction with HDAC Developer, Cat. # 50030.
Supplied As:
5 mM DMSO solution (100 µl)
DMSO solution
Instructions for use:
Materials :
HDAC Assay buffer (BPS catalog #50031)
HDAC Assay developer (BPS catalog #50030)
Fluorogenic HDAC Substrate (BPS catalog #50032)
HDAC2 (0.1 µg/µl) (BPS catalog #50001) or other class 1 or class 2b HDAC enzyme

Step 1 :
Add the following reagents to a low binding NUNC black plate (VWR catalog #62408-936):
HDAC Assay Buffer, 39 µl
1 mg/ml BSA, 5 µl
200 µM HDAC substrate, 5 µl
HDAC2, 1 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 350-380 nm and emission at 440-460 nm. “Blank” value (no enzyme negative control) is subtracted from all other values.
Storage / Stability:

Stable at least 12 months from date of receipt, when stored as directed
