Brand Family Upstate
Trade Name
  • Upstate
DescriptionProtein A Agarose/Salmon Sperm DNA, 2.5 mL
OverviewProtein A covalently bound to agarose by alkylamine linkage containing sonicated Salmon Sperm DNA. The salmon sperm DNA blocks non-specific interactions with the beads for use in chromatin IP (ChIP) assays. Note part number 16-157C present in the ChIP kits is not available separately, please purchase 16-157.
Alternate Names
  • ChIP agarose beads
  • ChIP agaraose A beads
Background InformationProtein A from Staphylococcus aureus has a very high affinity for the Fc regions of IgG molecules. Immoblisation of protein A on beads creates an affinity resin which can be used to purify IgG fractions from crude serum, ascites fluid or cell cuture media.
Product Information
Presentation10mM Tris-HCl, 1mM EDTA, pH 8.0 containing 0.05% sodium azide.
ApplicationRecombinant protein A covalently bound to agarose beads for use in chromatin immunoprecipitations (ChIP assays). Sonicated salmon sperm DNA is included to block non-specific DNA binding sites on agarose beads. Every lot qualified using an Acetyl Histone H4 and H3 ChIP assay.
Application NotesSuitable for use in chromatin immunoprecipitation (ChIPs) assays
