Recombinant Cynomolgus Monkey DC-SIGN/CD209 HA-tag Protein SDS-PAGE.
2 μg/lane of Recombinant Cynomolgus Monkey DC-SIGN/CD209 HA-tag (10504-DC) was resolved with SDS-PAGE under reducing (R) and non-reducing (NR) conditions and visualized by Coomassie® Blue staining, showing bands at 44-54 kDa.
Formulation, Preparation and Storage
What does CF mean?
CF stands for Carrier Free (CF). We typically add Bovine Serum Albumin (BSA) as a carrier protein to our
Adding a carrier protein enhances protein stability, increases shelf-life, and allows the recombinant
protein to be stored at a more dilute concentration.
The carrier free version does not contain BSA.
What formulation is right for me?
In general, we advise purchasing the recombinant protein with BSA for use in cell or tissue culture, or
as an ELISA standard.
In contrast, the carrier free protein is recommended for applications, in which the presence of BSA

Dendritic Cell-specific ICAM-3 Grabbing Non-integrin (DC-SIGN)/CD209 is a member of the C-type lectin family (1). The canonical DC-SIGN/CD209 isoform is a 40 kDa, 344 amino acid (aa) type II transmembrane protein, with the extracellular domain (ECD) containing a Ca2+-dependent carbohydrate-binding lectin domain (2). Within the ECD, cynomolgus DC-SIGN/CD209 shares 85% sequence identity with human DC-SIGN/CD209. The DC-SIGN/CD209 lectin domain binds mannose oligosaccharides on pathogens including HIV as well as self-glycoproteins including ICAMs (2, 3). DC-SIGN/CD209 binds to butyrophilin 2A1 and this interaction can be blocked by HIV pp120. DC-SIGN/CD209 is expressed on dendritic cells (DC) and inflammatory macrophages and contributes to antigen presentation (4,5).
