Siglec-3/CD33 Protein, Human, Recombinant (hFc & His)

Catalog No. TMPJ-00537
Synonyms: Myeloid Cell Surface Antigen CD33, CD33, Siglec-3, SIGLEC3, gp67, Sialic Acid-Binding Ig-Like Lectin 3

CD33 is a type I Lectin belonging to the Ig superfamily. CD33 contains an N terminal Ig like V type domain, which mediates sialic acid binding, followed by one Ig like C2 type domain, a transmembrane region and a cytoplasmic tail containing two conserved immunoreceptor tyrosine based inhibition motifs (ITIMs). Eleven human Siglecs have been characterized. Siglecs 5 to 11 share a high degree of sequence similarity with CD33/Siglec3 both in their extracellular and intracellular regions. They are collectively referred to as CD33 related Siglecs. CD33 related Siglecs have differential expression pattern within the hematopoietic system. They are involved in the regulation of cellular activation within the immune system. Siglec 3 expression is restricted to cells of myelomonocytic lineage. Siglec3 recruits SHP1 and SHP2 to its ITIMs upon phosphorylation.

Amino Acid Asp18-His259
Construction Recombinant Human Sialic Acid Binding Ig-like Lectin 3 is produced by our Mammalian expression system and the target gene encoding Asp18-His259 is expressed with a human IgG1 Fc, 6His tag at the C-terminus.
Protein Purity Greater than 95% as determined by reducing SDS-PAGE. (QC verified)
Molecular Weight 80 KDa, reducing conditions
Endotoxin Less than 0.1 ng/µg (1 EU/µg) as determined by LAL test.
Formulation Lyophilized from a 0.2 μm filtered solution of 20mM PB, 150mM NaCl, 2mM EDTA, pH 7.2.
Reconstitution Always centrifuge tubes before opening.Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100μg/ml. Dissolve the lyophilized protein in distilled water. Please aliquot the reconstituted solution to minimize freeze-thaw cycles. 
Stability & Storage

Lyophilized protein should be stored at ≤ -20°C, stable for one year after receipt. Reconstituted protein solution can be stored at 2-8°C for 2-7 days. Aliquots of reconstituted samples are stable at ≤ -20°C for 3 months.
Shipping

The product is shipped at ambient temperature. Upon receipt, store it immediately at the temperature listed below.
