The effect of Cripto produced in 3D microcarriers on C2C12 cell proliferation detected by the BrdU incorporation assay. ( A ) C2C12 myoblast proliferation was evaluated by the BrdU incorporation assay after being cultured for 48 h in serum-free medium containing Cripto produced in 3D microcarriers (Cripto (3D) ) or commercially available Cripto (Cripto (R&D) ). Also evaluated were a bFGF medium positive control and a serum-free medium negative control. ( B ) The recombinant Cripto induces myoblast proliferation in a dose-dependent pattern; increasing concentrations of Cripto (3D) and Cripto (R&D) were added to C2C12 cells, and proliferation was quantified by the BrdU incorporation assay. ( C ) Cell proliferation was further evaluated by counting the total number of live cells. The proliferative effect of Cripto (3D) was compared with that of commercial Cripto (R&D) . The data are presented as mean ± S.D. from at least three independent experiments. * indicates p < 0.05, ** indicates p < 0.01, *** indicates p < 0.001.

Concentration Assay:

Article Title: Biomanufacturing Recombinantly Expressed Cripto-1 Protein in Anchorage-Dependent Mammalian Cells Growing in Suspension Bioreactors within a Three-Dimensional Hydrogel Microcarrier
Article Snippet: To measure the concentrations of both the total purified protein and the active protein, an assay was carried out using a commercial ELISA kit (DuoSet, R&D systems, Minneapolis, Minnesota, United States). .. Serial dilutions of the concentrated protein were put into 96-well plates coated with either mouse Cripto antibody (for total concentration) or recombinant mouse activin receptor IB/Fc (for active protein concentration) (R&D systems AF1538 and 1477-AR, respectively). .. Briefly, 96–well plates were coated with 0.5 ng/mL of either activin RIB/ALK-4 (R&D systems 1477-AR) or Cripto antibody (R&D systems AF1538) in PBS (pH 7.5) overnight at 4 °C.

Recombinant:

Article Title: Cripto regulates skeletal muscle regeneration and modulates satellite cell determination by antagonizing myostatin
Article Snippet: .. After washing, cells were cultured in DMEM-FBS-0.5% medium containing soluble recombinant mouse Cripto (sCripto) at 5, 50, 100, 250, or 500 ng/mL (R&D Systems) and a homemade product ( 6 ), human basic FGF (10 ng/mL; R&D Systems), or neutralizing antibodies at 4 μg/mL (anti-Cripto, MAB1538; R&D Systems). .. A BrdU cell proliferation assay kit (Roche) was used following the manufacturer’s instructions.

Article Title: Cripto regulates skeletal muscle regeneration and modulates satellite cell determination by antagonizing myostatin
Article Snippet: Individual intact myofibers were placed in horse serum (HS)-coated, round-bottomed Eppendorf tubes and incubated with or without mouse sCripto (200 ng/mL; R&D Systems) or myostatin/GDF8 (50, 100, or 200 ng/mL; R&D Systems) in low-activation medium [10% (vol/vol) HS and 0.5% chicken embryo extract (CEE) in DMEM]. .. Myofibers were treated with sCripto or preincubated for 1 h with either blocking anti-Cripto (MAB1538, 4 μg/mL; R&D Systems) or anti-myostatin/GDF8 (GT15213, 10 μg/mL; Neuromics) antibodies before Cripto addition. ..
