Recombinant Human Siglec-3/CD33 Protein (RP00159)

Datasheet

Overview

Product name Recombinant Human Siglec-3/CD33 Protein
Catalog No. RP00159
Description Recombinant Human Siglec-3/CD33 Protein is produced by HEK293 expression system. The target protein is expressed with sequence (Asp18-His259) of human CD33/Siglec-3 (Accession #NP_001763.3) fused with an Fc, 6×His tag at the C-terminus.
Bio-Activity Measured by its binding ability in a functional ELISA. Immobilized Human CD33 Protein at 1μg/mL (100 μL/well) can bind CD33 Rabbit pAb with a linear range of 0.03-1.66 ng/mL.
Purity > 97% by SDS-PAGE.
Endotoxin < 0.1 EU/μg of the protein by LAL method.
Formulation Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.Contact us for customized product form or formulation.
Species Human
Myeloid cell surface antigen CD33 also known as Sialic acid binding Ig-like lectin 3, CD33 antigen or Siglec-3, is a member of the immunoglobulin superfamily and SIGLEC (sialic acid binding Ig-like lectin) family. This Single-pass type I membrane protein contains 1 Ig-like C2-type (immunoglobulin-like) domain and 1 Ig-like V-type (immunoglobulin-like) domain. CD33/Siglec-3 induces apoptosis in acute myeloid leukemia (in vitro). CD33/Siglec-3 can function as a sialic acid-dependent cell adhesion molecule and that binding can be modulated by endogenous sialoglycoconjugates when CD33 is expressed in a plasma membrane.

Storage Store the lyophilized protein at -20°C to -80 °C for long term.
After reconstitution, the protein solution is stable at -20 °C for 3 months, at 2-8 °C for up to 1 week.
Reconstitution Centrifuge the vial before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid votex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles.
