Carrier Free

What does CF mean?

CF stands for Carrier Free (CF). We typically add Bovine Serum Albumin (BSA) as a carrier protein to our recombinant proteins. 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 could interfere.


Formulation Lyophilized from a 0.2 μm filtered solution in PBS.
Reconstitution Reconstitute at 500 μg/mL in PBS.
Shipping The product is shipped at ambient temperature. Upon receipt, store it immediately at the temperature recommended below.
Stability & Storage: Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
  • 12 months from date of receipt, -20 to -70 °C as supplied.
  • 1 month, 2 to 8 °C under sterile conditions after reconstitution.
  • 3 months, -20 to -70 °C under sterile conditions after reconstitution.

Background: AICL/CLEC-2B

Activation-induced C-type lectin (AICL), also known as CLEC2B, is a 30-35 kDa variably glycosylated type-2 transmembrane member of the C-type lectin-like receptor (CTLR) family. AICL belongs to the subgroup of CLEC2 proteins that also includes CLEC2A/KACL, CLEC2D/LLT, and CD69/CLEC2C, all of which are encoded by the natural killer gene complex (1). Human AICL contains a single C-type lectin domain in its extracellular region and a 7 amino acid cytoplasmic tail (2). AICL is expressed on monocytes, macrophages, and granulocytes (3), and it is upregulated on TLR-activated monocytes and IL-12 + IL-18 activated NK cells (3, 4). AICL is an activating receptor that triggers TNF production by monocytes (3). It binds to NKp80 on NK cells, resulting in NK cell mediated lysis of the AICL expressing monocyte (3). In addition, the AICL-NKp80 axis mediates interactions between activated and resting NK cells (4).
