Custom Premix Selecting "Custom Premix" option means that all of the beads you have chosen will be premixed in manufacturing before the kit is sent to you.
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.
Magna ChIP™ Protein A + G magnetic beads: Recombinant protein G covalently bound to magnetic beads. Recombinant protein A plus recombinant protein G covalently bound to magnetic beads. This magnetic A+G blend allows for the use of a wider range of antibodies than A or G alone.
