            | Formulation | 
            Lyophilized from a 0.2 μm filtered solution of 20mM TrisHCl, 150mM NaCl, 1mM EDTA, pH 8.5 | 
        
        
            | 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. |

            | Background | 
            Grancalcin (GCA) is a cytoplasmic granule membrane protein that contains 4 EF-hand domains. GCA is calcium-binding protein and particularly abundant in human neutrophils. GCA is highly expressed in bone marrow, and it can be detected in neutrophils and macrophages. Calcium-binding protein GCA cooperates with SRI and LCP1, so it may play a role in the adhesion of neutrophils to fibronectin. GCA also may play a role in the formation of focal adhesions. |
