General description

Recombinant protein A covalently bound to magnetic beads. These beads provide users a rapid, reproducible and efficient reagent for collecting immunocomplexes for chromatin immunoprecipitations (ChIP) assays. Compared with conventional protein A agarose beads, protein A magnetic beads significantly reduce the handling time and mechanical stress on target immunocomplexes.

Application

Research Category
Epigenetics & Nuclear Function
Use 20 µL of bead suspension per ChIP application. Includes sufficient reagents for 50 precipitation reactions. Disperse beads thoroughly before pipetting by rapid vortex.
Used to detect/quantify: Protein A

Quality

Routinely evaluated by Chromatin immunoprecipitation (ChIP) using HeLa nuclear extracts and the Magna ChIP® A Kit (Cat. #17-610).

Physical form

Liquid suspension. Supplied as magnetic bead slurry in phosphate buffered saline, pH 7.4, containing 0.01% Tween®-20 and 0.09% sodium azide.

Storage and Stability

Stable for 1 year at 2-8°C from date of shipment. Do Not Freeze.
