Leukosialin (SPN) Human Recombinant Protein

One of the major glycoproteins of thymocytes and T lymphocytes. Plays a role in the physicochical properties of the T-cell surface and in lectin binding. Presents carbohydrate ligands to selectins. Has an extended rodlike structure that could protrude above the glycocalyx of the cell and allow multiple glycan chains to be accessible for binding. Is a counter-receptor for SN/Siglec-1. During T-cell activation is actively roved from the T-cell-APC (antigen-presenting cell) contact site thus suggesting a negative regulatory role in adaptive immune response.

Small volumes of SPN recombinant protein vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.

MBS717907 is a recombinant protein targeting SPN. Also known as Recombinant Human Leukosialin. Host: E Coli or Yeast or Baculovirus or Mammalian Cell.
