Human CD209 / DC-SIGN Protein, His Tag

Source : 

Human CD209, His Tag (CD9-H5246) is expressed from human 293 cells (HEK293). It contains AA Gln 59 - Ala 404 (Accession # Q9NNX6-1).

 

Molecule : CD209

 

Synonyms : DC-SIGN,CD209,DC-SIGN1,CLEC4L

 

Format : Powder

 

Category : Bio-Markers & CD Antigens

 

Accession : NP_066978.1

 

Storage : -20℃

 

Shipping condition : Powder,RT

 

Molecular Weight : 41.3 kDa

 

Characteristics :

This protein carries a polyhistidine tag at the N-terminus. The protein has a calculated MW of 41.3 kDa. The protein migrates as 40-50 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

 

Endotoxin Level : Less than 1.0 EU per μg by the LAL method.

 

Buffer : PBS, pH7.4

 

Description :

CD209 is also known as CLEC4L, DC-SIGN and CD209 antigen. Pathogen-recognition receptor expressed on the surface of immature dendritic cells (DCs) and involved in initiation of primary immune response. On DCs it is a high affinity receptor for ICAM2 and ICAM3 by binding to mannose-like carbohydrates. May act as a DC rolling receptor that mediates transendothelial migration of DC presursors from blood to tissues by binding endothelial ICAM2. Seems to regulate DC-induced T-cell proliferation by binding to ICAM3 on T-cells in the immunological synapse formed between DC and T-cells.
