Carrier Free

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.

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.

Background: SECTM1A

SECTM1A (secreted and transmembrane 1A), is 192 amino acid (aa) protein that shares approximately 45‑51%, 81%, and 43% aa sequence identity with human SECTM1 (also called K12), rat SECTM1, and mouse SECTM1B/K12, respectively, and appears to share structural and functional characteristics with other SECTM1 proteins. Human SECTM1 can be found either found as an approximately 27 kDa intracellular type I transmembrane protein that shows a perinuclear, Golgi‑like staining pattern, or as a 20 kDa soluble, secreted form, and is produced by some myeloid cells and by thymic epithelia and fibroblasts (1‑3). Stimulation with IFN‑ gamma is often necessary to detect human SECTM1 expression, and it is thought to be an interferon early‑response gene (1‑5). Mouse SECTM1A cDNA encodes a signal sequence, an extracellular domain with four potential N‑linked glycosylation sites, a transmembrane sequence, and a very short (approximately 6 aa) cytoplasmic sequence (6). SECTM1 proteins from human and mouse show species‑specific binding of CD7 and co‑stimulation of T cells, including enhancement of CD3‑induced proliferation (2‑4).
