ActoFactor™ Recombinant Human Lectin, galactoside-binding, soluble, 1

  • Specification
  • Recommended Products
Cat.No.
CSC-CTK0579
Description
Lectins, of either plant or animal origin, are carbohydrate binding proteins that interact with glycoprotein and glycolipids on the surface of animal cells. The Galectins are lectins that recognize and interact with beta-galactoside moieties. Galectin-1 is an animal lectin that has been shown to interact with CD3, CD4, and CD45. It induces apoptosis of activated T-cells and T- leukemia cell lines and inhibits the protein phosphatase activity of CD45. Recombinant human Galectin-1 is a 14.5 kDa protein containing 134 amino acid residues.
Organism
Human
Product Overview
Human LGALS1 expressed in E.coli
Molecular Mass
14.5 kDa
Size
CAT# CSC-CTK0579-50 (50 μg); CAT# CSC-CTK0579-250 (250 μg)
Expression System
E.coli
Purity
Greater than 98% as determined by SDS-PAGE and HPLC analysis.
Activity
Determined by its ability to chemoattract human blood monocytes. Chemotactic activity was observed at a concentration of 2.5 μg/ml with a peak response obtained at 250 μg/ml.
Endotoxin Level
Less than 1 EU/μg.
Formulation
Lyophilized from a sterile-filtered solution with no additives.
Reconstitution
Please centrifuge product before opening vial. The lyophilized protein should be reconstituted with distilled, sterile water to a concentration of 0.1-1.0 mg/ml. For further dilution, carrier protein (0.1% BSA or HSA) should be added to avoid loss of bioactivity.
Storage & Stability
The lyophilized protein, though stable at room temperature for up to 3 weeks, is best stored desiccated at -20°C. Reconstituted protein should be used immediately or stored long-term in undiluted working aliquots at -20°C. For long-term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Avoid repeated freeze-thaw cycles.
