    Reproducibility is key to advancing scientific discovery and accelerating scientists’ next breakthrough.

    Abcam is leading the way with our range of recombinant antibodies, knockout-validated antibodies and knockout cell lines, all of which support improved reproducibility.

    We are also planning to innovate the way in which we present recommended applications and species on our product datasheets, so that only applications & species that have been tested in our own labs, our suppliers or by selected trusted collaborators are covered by our Abpromise™ guarantee.

    In preparation for this, we have started to update the applications & species that this product is Abpromise guaranteed for.

    We are also updating the applications & species that this product has been “predicted to work with,” however this information is not covered by our Abpromise guarantee.

    Applications & species from publications and Abreviews that have not been tested in our own labs or in those of our suppliers are not covered by the Abpromise guarantee.

    Please check that this product meets your needs before purchasing.

ターゲット情報

  • 機能

    Plays a significant role in maintaining keratin filament organization in intestinal epithelia. When phosphorylated, plays a role in the secretion of mucin in the small intestine.
  • 組織特異性

    Expressed predominantly in the intestinal epithelium. Expressed in luminal cells of colonic mucosa. Also expressed in the Merkel cells of keratinized oral mucosa; specifically at the tips of some rete ridges of the gingival mucosa, in the basal layer of the palatal mucosa and in the taste buds of lingual mucosa.
  • 配列類似性

    Belongs to the intermediate filament family.
  • 発生段階

    First detected at embryonic week 8 in individual 'converted' simple epithelial cells of the developing intestinal mucosa. In later fetal stages, synthesis extends over most goblet cells and a variable number of villus enterocytes. In the developing gastric and intestinal mucosa, expressed in all enterocytes and goblet cells as well as certain 'low-differentiated' columnar cells, whereas the neuroendocrine and Paneth cells are negative.
  • 翻訳後修飾

    Hyperphosphorylation at Ser-13 occurs during the early stages of apoptosis but becomes less prominent during the later stages. Phosphorylation at Ser-13 also increases in response to stress brought on by cell injury.
    Proteolytically cleaved by caspases during apoptosis. Cleavage occurs at Asp-228.

    Question

    Dear colleagues

    One our customer bought Abcam cat# AB854 lot# GR94926-1, and she did note that this antibody was resospended in a almost red buffer: is it normal? Can you guarantee that this strange colour will not affect the performances?

    Please note that the same customer bough, several months ago, the same antibody (but with different lot number) and the buffer within was transparent.

    Thanks a lot

    Asked on Oct 01 2012

    Answer

    Thank you for your enquiry.

    I can confirm that ab854 Anti-Cytokeratin 20 antibody [Ks20.8]is provided as tissue culture supernatant, which we would expect to have a pink-red coloration. Therefore, I would not expect this to affect the antibody.

    The last vial purchased may have been purified and provided in clear buffer.

    I hope this will be helpful. If you have any further questions, please do not hesitate to contact us.
