Formulation, Preparation and Storage

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.

Carrier: 437-MR
Formulation Lyophilized from a 0.2 μm filtered solution in PBS with BSA as a carrier protein.
Reconstitution Reconstitute at 100 μg/mL in sterile PBS containing at least 0.1% human or bovine serum albumin.

Background: BMPR-IA/ALK-3

Bone Morphogenetic Protein Receptor IA (BMPR-IA), also known as ALK-3, BRK-1, and CD292, is a glycosylated 60 ‑ 65 kDa type I receptor in the TGF‑ beta serine/threonine kinase receptor family (1 ‑ 3). Binding of TGF‑ beta superfamily ligands induces formation of a heterotetrameric complex that contains two chains each of a type I and a type II receptor in multiple combinations. The type II receptors phosphorylate the type I receptors which then phosphorylate and activate Smad signal transduction proteins (1, 2). Mature mouse BMPR-IA consisits of a 129 amino acid (aa) extracellular domain (ECD), a 24 aa transmembrane segment, and a 356 aa cytoplasmic region that contains the tyrosine kinase domain (4, 5). Within the ECD, mouse BMPR-IA shares 98% aa sequence identity with human and rat BMPR-IA. BMPR-IA is involved in the development and function of a wide range of tissues. During early embryogenesis it is required for migration of the anterior visceral endoderm (AVE) and proper development of the anterior-posterior axis (6). Tissue-specific conditional knockout experiments have demonstrated the importance of BMPR-IA in the development and morphogenesis of the heart, lung, palate, teeth, and mandible (7 - 9). In the adult, BMPR-IA plays a role in glucose-stimulated insulin secretion by pancreatic beta cells, osteoclast activity and bone remodeling, reactive astrocyte-mediated scar formation following spinal cord injury, and ovulation and fertility (10 - 13).
