Background Information
CD44 is a type I transmembrane glycoprotein that mediates cell-cell and cell-matrix interactions through its affinity for hyaluronic acid (HA) and possibly also through its affinity for other ligands. 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. This protein exists in multiple forms (with molecular weight ranging from 16 kDa to over 200 kDa) generated by alternative RNA splicing and extensive post-translational modifications.

Reviews
What customers say
Both reviews are for Western Blot applications. One user (4/5) reported the antibody stained cell supernatants effectively but suggested using a higher concentration. The other (5/5) confirmed it worked well at a 1:1000 dilution on glioblastoma cells. Overall, users find the antibody reliable for WB, with a minor note that increasing the concentration may improve signal in some samples.
The reviews below have been submitted by verified Proteintech customers who received an incentive for providing their feedback.
