Recombinant Human SIGLEC8 protein, His-tagged

• Cat.No.: SIGLEC8-772H
• Product Overview: Recombinant Human SIGLEC8 (Met17-Ala363) protein was fused to His-tag at C-terminus and expressed in human 293 cells (HEK293).

Specification

• Description: Siglec-8 is also known as SIGLEC8, SAF2, SIGLEC-8, SIGLEC8L and sialic acid binding Ig like lectin 8. Siglec-8 was first identified by CD33 homology screening of ESTs from a cDNA library generated from a patient diagnosed with idiopathic hypereosinophilic syndrome and was originally termed SAF-2 (sialoadhesin family 2). At the tissue level, Siglec-8 mRNA was found to be most highly expressed in lung, PBMCs, spleen, and kidney. Two splice variants of Siglec-8 exist. The initially characterized form contains 431 amino acid residues in total, subsequently, a longer form of Siglec-8, initially termed Siglec-8L. Both forms of Siglec-8 are found in eosinophils and contain a V-set domain with lectin activity and two C2-type Ig repeat domains in the extracellular region.
• Source: HEK293
• Species: Human
• Tag: His
• Predicted N Terminal: Met17
• Form: Lyophilized from 0.22 μm filtered solution in PBS, pH7.4, 10% trehalose.
• Molecular Mass: The protein has a calculated MW of 39.7 kDa. The protein migrates as 50-55 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
• Protein length: Met17-Ala363
• Endotoxin: Less than 1.0 EU per μg by the LAL method.
• Purity: >95% as determined by SDS-PAGE.
• Storage: For long term storage, the product should be stored at lyophilized state at -20 centigrade or lower.
  Please avoid repeated freeze-thaw cycles.
  This product is stable after storage at:
  -20 to -70 centigrade for 12 months in lyophilized state;
  -70 centigrade for 3 months under sterile conditions after reconstitution.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4℃ before opening to recover the entire contents.
