Biological Activity

Sialic acid-binding Ig-like lectin 9(Siglec 9) is expressed by peripheral blood leukocytes, and found in liver, fetal liver, bone marrow, placenta, spleen and so on. It is a putative adhesion molecule that mediates sialic-acid dependent binding to cells. It also binds to alpha-2,3- or alpha-2,6-linked sialic acid.

Recombinant Human Sialic Acid-binding Ig-like Lectin 9 expressed the target gene encoding Gln18-Gly348 with a human IgG1 Fc tag at the C-terminus.


Accession: AAH35365.2

Endotoxin < 1 EU/µg

Apparent Molecular Weight: 90-120 KDa, reducing conditions

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4.

Chemical Information

Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.

E-selectin, also known as endothelial leukocyte adhesion molecule-1 (ELAM-1) and CD62E, is an inducible adhesion molecule that is expressed on the surfaces of stimulated vascular endothelial cells and is sometimes involved in cancer cell metastasis.

Recombinant Human DPP4/CD26 (Mammalian, C-6His)

DPP4/CD26 is a signal-anchor for type II membrane protein that belongs to the peptidase S9B family. DPP4/CD26 acts as a positive regulator of T-cell coactivation, by binding at least ADA, CAV1, IGF2R, and PTPRC. It’s binding to CAV1 and CARD11 induces T-cell proliferation and NF-kappa-B activation in a T-cell receptor/CD3-dependent manner.

Recombinant Human USP14 (E.coli, N-6His)

USP14 belongs to the ubiquitin-specific processing (USP) family which is a deubiquitinating enzyme (DUB) with His and Cys domains. USP14 acts also as a physiological inhibitor of endoplasmic reticulum-associated degradation (ERAD) under the non-stressed condition by inhibiting the degradation of unfolded endoplasmic reticulum proteins via interaction with ERN1.
