CBX1 Inhibitor Screening Assay Kit

Products from BPS Bioscience require a minimum order value above 400€

Applications: Useful for the study of chromodomain binding assays, screening inhibitors, and selectivity profiling.

Contraindications: Green and blue dyes that absorb light in the AlphaScreen signal emission range (520-620 nm), such as Trypan Blue. Avoid the use of potent singlet oxygen quenchers such as sodium azide (NaN3) or metal ions (Fe2+, Fe3+, Cu2+, Zn2+ and Ni2+). The presence of >1% RPMI 1640 culture medium leads to a signal reduction due to the presence of excess biotin and iron in this medium. MEM, which lacks these components, does not affect AlphaScreen assays.

Description: The CBX1 Inhibitor Screening Assay Kit is designed to measure the inhibition of CBX1 binding to its substrate. The kit comes in a convenient AlphaLISA® format, with enough biotinylated peptide substrate, assay buffer, detection buffer and purified GST-tagged CBX1 chromodomain to perform a total of 384 enzyme reactions. The key to the kit is the specific binding of the CBX1 chromodomain to the methylated-peptide substrate. With this kit, only three simple steps on a microtiter plate are required. First, a sample containing CBX1 and an inhibitor of choice is incubated with the biotinylated substrate for one hour. Next, acceptor beads are added, then donor beads, followed by reading the Alpha-counts.

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

Warnings: Avoid freeze/thaw cycles.

Biosafety Level: Not applicable (BSL-1)
