CD44 expression is also upregulated in subpopulations of cancer cells and is recognized as a molecular marker for cancer stem cells (PMID: 29747682). It is a cell-surface receptor that mediates cell-cell and cell-matrix interactions through its affinity for hyaluronic acid (HA) and possibly also through its affinity for other ligands (PMID: 10694938). Adhesion with HA plays an important role in cell migration, tumor growth and progression. CD44 is also involved in lymphocyte activation, recirculation and homing, and in hematopoiesis.\n\u003cb\u003eSpecification\u003c\/b\u003e\nTested Reactivity: mouse, rat\nHost \/ Isotype: Rabbit \/ IgG\nClass: Polyclonal\nType: Antibody\nImmunogen: CatNo: Eg1458 Product name: Recombinant Rat CD44 protein (rFc Tag) (HPLC verified) Source: mammalian cells -derived, pHZ-KIsec-C-rFc Tag: C-rFc Domain: 22-271 aa of XM_006234631.3 Sequence: QQQIDLNITCRYAGVFHVEKNGRYSISRTEAADLCEAFNTTLPTMAQMELALSKGFETCRYGFIEGHVVIPRIHPNAICAANNTGVYILLASNTSHYDTYCFNASAPLEEDCTSVTDLPNSFDGPVTITIVNRDGTRYSKKGEYRTHQEDIDASNIIDEDVSSGSTIEKSTPEGYILHTDLPTSQPTGDRDDAFFIGSTLATSDGDSSMDPRGGFDTVTHGSELAGHSSGNQDSGVTTTSGPARRPQIPE Predict reactive species\nFull Name: Cd44 molecule\nCalculated Molecular Weight: 40 kDa\nObserved Molecular Weight: 80-95 kDa\nGenBank Accession Number: XM_006234631.3\nGene Symbol: Cd44\nGene ID (NCBI): 25406\nConjugate: Unconjugated\nForm: Liquid\nPurification Method: Antigen affinity Purification\nUNIPROT ID: O70509\nStorage Buffer: PBS with 0.02% sodium azide and 50% glycerol, pH 7.3.\nStorage Conditions: Store at -20°C.
