Related Product Information for anti-Cd44 antibody
Recent studies indicate that the expression of CD44 on the cell surface changes profoundly during tumor metastasis, particularly during the progression of various carcinomas. Sequencing analysis reveals that CD44 exists in different forms (at least 15 isoforms have been identified) that are variants of the common or standard hemopoietic form CD44s. Specifically, the human CD44 gene contains 19 exons, out of which 10 exons can potentially be alternatively spliced. In particular, CD44s contains exons 1-15 and exons 15-19. The other exons (e.g. 6-14) are also spliced in a variety of different cells. For example, epithelial cells contain exons 12-14 inserted into the CD44s transcripts. This isoform has been designated as CD44E. Other CD44 variants CD44v) have the same sequences at the two ends of the molecule, but differ in a middle region (with different numbers of additional exons) located on the external side of the cell membrane. It has been suggested that expression of CD44 variants with the additional exon 11 (so-called v7) is responsible for tumor progression and metastasis. In fact, CD44v7 expression has been used as an indicator of metastasis.

Uniprot Description
CD44: Receptor for hyaluronic acid (HA). Mediates cell-cell and cell-matrix interactions through its affinity for HA, and possibly also through its affinity for other ligands such as osteopontin, collagens, and matrix metalloproteinases (MMPs). Adhesion with HA plays an important role in cell migration, tumor growth and progression. Also involved in lymphocyte activation, recirculation and homing, and in hematopoiesis. Altered expression or dysfunction causes numerous pathogenic phenotypes. Great protein heterogeneity due to numerous alternative splicing and post-translational modification events. Interacts with PKN2. Interacts with HA, as well as other glycosaminoglycans, collagen, laminin, and fibronectin via its N-terminal segment. Interacts with ANK, the ERM proteins (VIL2, RDX and MSN), and NF2 via its C-terminal segment. Isoform 10 (epithelial isoform) is expressed by cells of epithelium and highly expressed by carcinomas. Expression is repressed in neuroblastoma cells. 19 isoforms of the human protein are produced by alternative splicing.

It is sometimes possible for the material contained within the vial of
"CD44V7, Polyclonal Antibody" to become dispersed throughout the inside of
the vial, particularly around the seal of said vial, during shipment and storage. We always
suggest centrifuging these vials
to consolidate all of the liquid away from the lid and to the bottom of the vial prior to
opening. Please be advised that
certain products may require dry ice for shipping and that, if this is the case, an
additional dry ice fee may also be
required.
