Siglec-9 Protein, Human (HEK293, Fc)

Siglec-9 Protein, a putative adhesion molecule, mediates sialic-acid dependent cellular binding with a preference for alpha-2,3- or alpha-2,6-linked sialic acid.Its sialic acid recognition site may undergo masking through cis interactions with sialic acids on the same cell surface.Siglec-9 Protein, Human (HEK293, Fc) is the recombinant human-derived Siglec-9 protein, expressed by HEK293 , with C-hFc labeled tag.

Siglec-9 protein, identified as a putative adhesion molecule, serves as a mediator in sialic-acid dependent cellular binding. It exhibits a preference for binding to alpha-2,3- or alpha-2,6-linked sialic acid. Notably, the sialic acid recognition site of Siglec-9 may undergo masking due to cis interactions with sialic acids on the same cell surface.

80-110 kDa

Greater than 95% as determined by Tris-Bis PAGE.

Lyophilized powder

Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4. Normally 5% trehalose is added as protectant before lyophilization.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O.

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
