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.

Background: Integrin alpha 10 beta 1

Integrin alpha 10 beta 1 is one of twelve integrin family adhesion receptors that share the beta 1 subunit (1‑3). The non‑covalent heterodimer of 160 kDa alpha 11 and 130 kDa beta 1/CD29 type I transmembrane glycoprotein subunits is expressed mainly on chondrocytes within cartilage, but also in fibrous connective tissues such as heart valves and ligaments (3, 4). The alpha 10 extracellular domain (ECD) contains an I (inserted) domain which includes the ligand binding site (2, 3, 5). The beta 1 ECD contains a vWFA domain, which participates in binding. Each subunit then has a transmembrane sequence and a short cytoplasmic tail. The dimer is folded when it is least active. Divalent cations and intracellular (inside‑out) signaling convert it to its most active, extended and open conformation (1, 2). The 1100 amino acid (aa) mouse  alpha 10 extracellular domain (ECD) shares 96% aa sequence identity with  rat and 88‑89% with human, rabbit, porcine, canine and bovine alpha 10, while the 708 aa mouse beta 1 ECD shares 98% aa identity with rat and 93‑94% with human, bovine, porcine, ovine, canine and feline beta 1. A potential mouse alpha 10 splice variant diverges at aa 1039 and is terminated prematurely. If translated, this variant would result in a secreted protein (6). I domain‑containing beta 1 integrins alpha 1 beta 1, alpha 2 beta 1, alpha 10 beta 1 and alpha 11 beta 1 all bind collagens; all but alpha 11 beta 1 also bind laminins (5, 7, 8). During cartilage differentiation, alpha 10 beta 1 is thought to be the main integrin binding type II and IX cartilage collagens (3‑5, 7‑10). However, deletion of mouse alpha 10 causes a mild phenotype including slightly shortened bones and narrowed hypertrophic zones, indicating that another collagen‑binding integrin, likely alpha 2 beta 1, may compensate for alpha 10 beta 1 functions (11). Migration of melanoma cells has been noted to correlate with alpha 10 beta 1 expression (12).

  1. What is the amino acid sequence of the acidic and basic tails?

    • Acidic and basic tails are added to the protein to help facilitate optimal activity. While we generally include sequence information on the product datasheet, the sequences of these tails are considered confidential information.
