The name Annexin pools over 160 different proteins. They are united by similar characteristics such as the ability to bind phosphatidylserine (PS) in a calcium dependent manner and a 70 amino acid repeat sequence called Annexin repeat.


  • Better ChIP results with less sample material thanks to Chromatrap ChIP spin columns.
  • The open structure of the scaffold promotes molecular movement for better sample mixing while the inert matrix material guarantees unparalleled specificity and low background.
  • The result is an excellent signal-to-noise ratio and wide dynamic range that allow significantly smaller sample volumes.
  • Chromatrap offers spin column kits for various ChIP applications ranging from ChIP/qPCR and ChIP-seq to ChIP from FFPE tissue samples.
  • In addition, sets of antibodies against established control loci and the respective qPCR primers are offered as ChIP controls.


  • Their purpose is to function as a barrier, protecting the body from mechanical damage, invading micro organisms and the loss of body fluids.
  • Detection of epithelial cells has a central role in research on cancer diseases.
  • A range of antibodies has been established for detection of individual epithelial cells.
  • Some standard markers are: anti-epithelial membrane antigen (EMA) antibody and pan-cytokeratin antibody
