Immunogen affinity purified
Innovator's Reward
Test in a species/application not listed above to receive a full credit towards a future purchase.


  • ELISA 1:5000-1:30000
  • Western Blot 1:500-1:3000
Application Notes
Specific conditions for reactivity should be optimized by the end user. Expect a band approximately 37 kDa in size corresponding to Swi6 protein by western blotting in the appropriate cell lysate or extract.
Theoretical MW
37.29 kDa.
Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

Reactivity Notes

Reactive with Swi6 from Schizosaccharomyces pombe.
BLAST analysis indicates that cross reactivity with homologues of this protein from other sources is not likely

Immunogen affinity purified


Swi6 Antibody is an affinity purified antibody produced by immunoaffinity chromatography using peptide coupled to agarose beads followed by solid phase adsorption to remove any unwanted reactivities

Store this antibody at -20C prior to opening. Aliquot contents and freeze at -20C or below for extended storage. Avoid cycles of freezing and thawing. Centrifuge product if not completely clear after standing at room temperature. This product is stable for several weeks at 4C as an undiluted liquid. Dilute only prior to immediate use.

Alternate Names for Swi6 Antibody

  • Chromatin-associated swi6 protein; Regulatory protein SWI6


The chromatin structure of Fission yeast centromeres is regulated epigenetically. In the central core domain, the histone H3 variant Cnp1(CENP-A) plays a key role. In the flanking heterochromatin domain, histones are kept underacetylated by the histone deacetylases (HDACs) Clr3, Clr6 and Sir2, and methylated by Clr4 methyltransferase (HMTase) to create a specific binding site for the Swi6 protein. Swi6 then directly mediates cohesin binding to the centromeric heterochromatin. Recognizes and binds histone H3 tails methylated at Lys-9, leading to epigenetic repression. Involved in the repression of the silent mating-type loci MAT2 and MAT3. May compact MAT2/3 into a heterochromatin-like conformation which represses the transcription of these silent cassettes. Swi6 interacts with histone H3 methylated at Lys-9 and with the cohesin subunit psc3. Swi6 associates with Swi4 to activate HO and many other late G1-specific transcripts in budding yeast. In contrast, histone H3 methylated at Lys9 and its interacting protein Swi6/HP1, which define heterochromatin, coated extended domains associated with a variety of repeat elements and small islands corresponding to meiotic genes. Contains two chromo domains.
