Description

Galectin-1, a polypeptidic factor that can have major effects on cell growth and apoptosis, is an important regulator of leukocyte function and tumor angiogenesis. Galectin-1 belongs to a family of 15 structurally related β-galactoside binding proteins that are able to control a variety of cellular events, including cell cycle regulation, adhesion, proliferation, and apoptosis. Human Galectin-1 shares 88% aa sequence identity with mouse, equine and ovine, 90% with rat, and 87% with bovine and porcine Galectin-1. Recombinant human galectin-1 to three porphyrin compounds: Zn-porphyrin (ZnTPPS). Mn-porphyrin and Au-porphyrin. These compounds are widely applied in the photodynamic therapy of cancer. Galectin-1 can also modulate cell-cell and cell-matrix interactions.

Biological Activity

The biological activity determined by a chemotaxis bioassay using human blood monocytes is in a concentration range of 1.0-10 ng/mL. Fully biologically active when compared to standard.

Endotoxin

< 0.1 EU per 1μg of the protein by the LAL method.

Formulation

Lyophilized from a 0.2 μm filtered concentrated solution in PBS, pH 7.4, with 1 mM DTT.

Reconstitution

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20. Further dilutions should be made in appropriate buffered solutions.

 

Shipping and Storage

The products are shipped with ice pack and can be stored at -20 ℃ for 1 year.

1 month, 2 to 8 °C under sterile conditions after reconstitution.

3 months, -20 °C under sterile conditions after reconstitution.

Recommend to aliquot the protein into smaller quantities when first used and avoid repeated freeze-thaw cycles.
