Keratin 33B Antibody (S-28) is a high quality monoclonal Keratin 33B antibody (also designated Keratin 33B antibody) suitable for the detection of the Keratin 33B protein of human origin. Keratin 33B Antibody (S-28) is available as the non-conjugated anti-Keratin 33B antibody. The Keratin multigene family is made of the "soft" epithelial cytokeratins and the "hard" hair Keratins. While the epithelial cytokeratins are involved in the layering and formation of epithelia, the hair Keratins are responsible for creating nails and hair. There are two types of hair Keratins: the acidic type I hair Keratin proteins and the basic/neutral type II hair Keratin proteins. Keratin 28 (Keratin, type I cytoskeletal 28), also known as Keratin-25D or type I inner root sheath-specific keratin-K25irs4, is a 464 amino acid cytoplasmic protein that belongs to the intermediate filament family. Highly expressed in scalp and skin, Keratin 28 is found at lower levels in thymus and the medulla of beard hair. The gene encoding Keratin 28 maps to human chromosome 17q21.2 and mouse chromosome 11 D.

I am using Keratin 33B (S-28): sc-100928 for immunofluorescence, what dilution of this antibody should I use?
Asked by: Randy McDonald
Thank you for your question. We recommend a starting dilution of 1:50. However, optimal antibody concentration should be determined by titration. Please find our full immunofluorescence protocol here:
