Reconstitution	Reconstitute in sterile water for a stock solution. Adjust the volume of sterile water so that, after reconstitution, the final stock concentration matches the value indicated on the product label or datasheet. RECONSTITUTION PROTOCOL 1. Allow the product to be reconstituted and the reconstitution diluent to reach room temperature. 2. Tap or briefly centrifuge the product vial before opening to dislodge any lyophilized material that may be dispersed on the wall or cap of the vial. 3. Use the diluent and stock concentration recommended in the product datasheet. If preparing a stock concentration higher than recommended, contact Technical Service. 4. After adding the diluent, re-cap the vial and invert gently by hand or place on a slow rocking platform to allow the reconstitution diluent to coat all the surfaces inside the vial. Note: Do not mix by vortexing or by pipetting the material up and down. 5. Allow the vial to sit at room temperature with gentle agitation for at least 15 minutes before aliquotting or using. 6. Store the reconstituted material in single use aliquots in polypropylene or siliconized tubes. Aliquots of 10 μL or larger are recommended.
Shipping	In general, proteins are provided as lyophilized powder/frozen liquid. They are shipped out with dry ice/blue ice unless customers require otherwise.
Stability and Storage	Use a manual defrost freezer and avoid repeated freeze thaw cycles. Store at 2 to 8°C for frequent use. Store at -20 to -80°C for twelve months from the date of receipt.
Alternate Names	Endo-beta-N-acetylglucosaminidase
Background	Endo-beta-N-acetylglucosaminidase EndoS (Endo S) is a ~111 kDa protein. Endoglucosidase that acts as a host immune evasion factor by mediating hydrolysis of the N-linked glycan from the Fc region of host immunoglobulin-gamma (IgG) during infection. Specifically catalyzes the hydrolysis of the beta-1,4 linkage between the first two N-acetylglucosamine residues of the complex-type N-linked glycan located on 'Asn-297' of the Fc region of IgG antibodies (IGHG1, IGHG2, IGHG3 or IGHG4), thereby preventing interaction between IgGs and Fc receptors and ability to activate the complement pathway. Shows a specificity for biantennary complex type N-glycans; does neither cleave larger complex type glycans nor oligomannose and nor hybrid-type glycans. Specifically acts on IgGs; does not act on immunoglobulin alpha, beta, delta or mu. 1. Collin, M. et al. (2001) The EMBO journal 20, 3046-55. PMID: 11406581 2. Collin, M. et al.
