Siglec-5 Protein, Human (HEK293, Fc)

Siglec-5 Protein, a putative adhesion molecule, participates in sialic-acid dependent cellular binding, showing equal affinity for alpha-2,3-linked and alpha-2,6-linked sialic acid. Its sialic acid recognition site may be masked through cis interactions with sialic acids on the same cell surface. Siglec-5 Protein, Human (HEK293, Fc) is the recombinant human-derived Siglec-5 protein, expressed by HEK293 , with C-hFc labeled tag.

Siglec-5 protein, a putative adhesion molecule, is implicated in sialic-acid dependent cellular binding, displaying equal affinity for both alpha-2,3-linked and alpha-2,6-linked sialic acid. Notably, the sialic acid recognition site of Siglec-5 may be subject to masking through cis interactions with sialic acids on the same cell surface.

Measured by its binding ability in a functional ELISA. Immobilized Siglec-5 at 1 μg/mL (100 μL/well) can bind Anti Siglec-5 antibody. The ED₅₀ for this effect is 0.7241 μg/mL.

Approximately 90-120 kDa due to the glycosylation.

• 
  Greater than 95% as determined by reducing SDS-PAGE.

Lyophilized powder

Lyophilized from a 0.2 μm filtered solution of 20 mM PB, 150 mM NaCl, pH 8.0 or PBS, pH 6.5, 8% trehalose.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years from date of receipt. 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.
