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: 7790-WN

Background: Wnt-16b

Wnt‑16 is a 40 kDa protein within the Wnt family of secreted, highly conserved, cysteine‑rich, palmitoylated cell signaling glycoproteins that play important roles in vertebrate developmental pattern formation, cell fate decision, axon guidance, and tumor formation (1‑3). Wnt‑16a and Wnt‑16b isoforms in humans differ in the signal sequence and the first two amino acids (aa) of the mature protein (2, 3). Wnt‑16b is the more conserved isoform and is widely expressed, while Wnt‑16a is expressed mainly in the human pancreas (3). Mature human Wnt‑16b shares 92%, 93%, and 95% aa sequence identity with mouse/rat, rabbit/porcine/equine, and bovine Wnt‑16, respectively. Wnt‑16 expression is detected on uterine stroma adjacent to the luminal epithelium during implantation (4). It is up‑regulated during the first embryonic lymphoid progenitor differentiation (5). Congenital heart defects correlate with elevated Wnt‑16 in mouse embryos and human amniotic fluid (6). Low cortical bone thickness and bone mineral density correlate with deletion of Wnt‑16 in mice and a Wnt‑16 missense SNP in humans (7). Wnt‑16 is over‑expressed in cells undergoing replicative senescence, and is up‑regulated in articular cartilage by injury and osteoarthritis (8, 9). Wnt‑16b expression in skin is up‑regulated in human basal cell carcinomas, enhancing cell survival (10). Its expression is also up‑regulated by DNA damage (radiation and chemotherapy) in stroma surrounding prostate tumors, causing enhanced survival and treatment resistance in the tumor cells (11). Pre‑B acute lymphoblastic leukemia with t(1;19) translocation, creating an E2A‑Pbx1 fusion protein, also causes up‑regulation of Wnt‑16 that confers resistance to apoptosis (12, 13). Wnt‑16 signaling through both canonical and JNK‑mediated (non‑canonical) pathways is reported (8‑10).
