            | Description | 
            Recombinant Human Galectin-1 is produced by our E. coli expression system. The target protein is expressed with sequence (Ala2-Asp135) of Human LGALS1 fused with a 6His tag at the C-terminus. |

            | Formulation | 
            Lyophilized from a 0.2 μm filtered solution of 10mM PB, 200mM NaCl, 2mM DTT, pH 7.0 | 
        
        
            | Shipping | 
            The product is shipped at ambient temperature. | 
        
        
            | Reconstitution | 
            Always centrifuge tubes before opening. Do not mix by vortex or pipetting. 
            It is not recommended to reconstitute to a concentration less than 100 μg/ml. 
            Dissolve the lyophilized protein in 1X PBS. 
            Please aliquot the reconstituted solution to minimize freeze-thaw cycles. | 
        
        
            | Storage | 
            Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks. 
            Reconstituted protein solution can be stored at 4-7°C for 2-7 days. 
            Aliquots of reconstituted samples are stable at < -20°C for 3 months. | 
        
        
            | Biological Activity | 
            Measured by its ability to agglutinate human red blood cells. | 
        
        
            | Purity | 
            Greater than 95% as determined by SEC-HPLC and reducing SDS-PAGE. | 
        
        
            | Endotoxin | 
            Less than 0.1 ng/μg (1 IEU/μg). |

            | Background | 
            Galectin-1 is a member of growing family of evolutionary conserved animal lectins. Galectin-1 is widely expressed in many cells and tissues. Galectins consists of a Galectin domain and two Beta-galactoside binding domains. Galectin-1 can binds LGALS3BP and interacts with CD2, CD3, CD4, CD7, CD43 and CD45. Galectin-1 may act as an autocrine negative growth factor which regulates apoptosis, cell proliferation and cell differentiation. In addition, Galectin-1 plays improtant roles in immunosuppressive and antiinflammatory properties. |
