Product Description	Recombinant Human CD89 Protein is expressed from HEK293 with His tag at the C-Terminus.It contains Gln22-Asn227.
Product Background	CD89 (Fc alphaRI) is the human myeloid IgA Fc receptor expressed on cells, such as neutrophils, eosinophils and monocytes/macrophages.CD89 is a transmembrane glycoprotein that binds both subclasses of IgA in all its molecular forms (i.e. monomeric, dimeric and secretory IgA) via a region of its membrane-distal EC1 domain.
Product Category	Recombinant Protein / Antibody discovery

Protein	CD89
Synonyms	IgA Fc receptor; CD89; FCAR; CTB-61M7.2; FcalphaRI; Fc fragment of IgA
Accession	NP_001991.1
Species	Human
Biotinylated	no
Amino Acid Range	Gln22-Asn227
Molecular Weight	The protein has a predicted MW of 24.6 kDa. Due to glycosylation, the protein migrates to 45-65 kDa based on Bis-Tris PAGE result.
Product Tag	C-His
Expression System	HEK293
Purity	> 95% as determined by Bis-Tris PAGE;> 95% as determined by HPLC
Endotoxin	Less than 1EU per ug by the LAL method.

Form	Lyophilized
Shipping	Shipped at ambient temperature.
Formulation	Lyophilized from 0.22um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution	Centrifuge the tube before opening. Reconstituting to a concentration more than 100 ug/ml is recommended. Dissolve the lyophilized protein in distilled water.
Stability And Storage	-20 to -80°C for 12 months as supplied from date of receipt.；-80°C for 3 months after reconstitution.；Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.

	Human CD89 on Bis-Tris PAGE under reduced condition. The purity is greater than 95%.
	The purity of Human CD89 is greater than 95% as determined by SEC-HPLC.
