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.


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


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.

The cyclin-dependent kinase inhibitor p21/WAF1/CIP1 is an important regulator of cell cycle progression, senescence, and differentiation. Genotoxic stress leads to activation of the tumor suppressor p53 and subsequently to induction of p21 expression. Here we show that the tumor suppressor...
