ProDots Recombinant Human BMP-4 Protein

Supplied as ready-to-use 5 ug protein balls

Pre-aliquoted, lyophilized protein dots for use in cell culture medium

  • Rolls out of bottle for easy cell culture medium preparation
  • Eliminates time spent aliquoting
  • One protein dot can be used to make 500 mL of 10 ng/mL cell culture medium

Why use ProDots™ Proteins Instead of Standard Lyophilized Protein?

ProDots® proteins are designed to reduce cell culture media preparation time while ensuring optimal protein recovery and bioactivity. Unlike standard lyophilized protein, which is shipped as a diffuse residue within a vial, ProDots® proteins are neatly bundled into the shape of a ball. In this form ProDots® proteins can be rolled directly into cell culture media. ProDots® proteins rehydrate instantly in media to maximize the recovery of purchased protein and to reliably reconstitute it at a desired concentration for use in cell culture media. ProDots® proteins can be conveniently stored at room temperature where they will remain stable for 6 months or at 4 ºC where they will remain stable for 12 months. The accessible storage and high stability of ProDots® proteins makes them ideal for quick and easy preparation of cell culture media.

What are ProDots® Proteins?

ProDots® proteins are R&D Systems industry-leading quality, highly bioactive proteins packaged into easy-to-use lyophilized “dots”. Designed to be stable at 4 ºC and to dissolve instantly, ProDots® proteins can be rolled into cell culture media to quickly produce media with a desired working protein concentration.

  • Purity
    >95%, by SDS-PAGE under reducing conditions and visualized by silver stain.
  • Endotoxin Level
    <0.01 EU per 1 μg of the protein by the LAL method.
  • Activity
    Measured by its ability to induce alkaline phosphatase production by ATDC5 mouse chondrogenic cells. Binnerts, M.E. et al. (2004) Biochem. Biophys. Res. Commun. 315(2):272. The ED50 for this effect is typically 2.5-15.0 ng/mL.

Data Images
1 μg/lane of ProDots® Recombinant Human BMP-4 was resolved with SDS-PAGE under reducing (R) and non-reducing (NR) conditions and visualized with silver staining, showing multiple bands at 22-25 kDa and 37-41 kDa, respectively. Multiple bands in the gel are due to variable glycosylation.
ProDots® Recombinant Human
BMP-4 induces alkaline phosphatase production in the ATDC5 mouse chondrogenic cell line. The ED50 for this effect is typically 2.5-15.0 ng/mL.
Background: BMP-4

BMPs are secreted signaling molecules that comprise a subfamily of the TGF-beta superfamily and were originally identified as regulators of cartilage and bone formation. There are at least 20 structurally and functionally related BMPs, most of which play roles in embryogenesis and morphogenesis of various tissues and organs. Biologically active BMPs are usually homodimers containing a characteristic cysteine knot structure. Heterodimers, BMP-2/BMP-7 and BMP-4/BMP-7 have also been suggested to exist and function in vivo. They are more potent inducers of bone formation than their respective homodimers. In addition, heterodimers, but not homodimers, are ventral mesoderm inducers. Heterodimer activity may be mediated by a different or additional receptor subtype.

Decapentaplegic (Dpp) is one of at least five TGF-beta superfamily ligands identified in the Drosophila genome. Dpp, a functional ortholog of mammalian BMP-2 and BMP-4, is a morphogen and plays an essential role in Drosophila development. Dpp regulates embryonic dorsal-ventral polarity and is required for gut morphogenesis and outgrowth and patterning of imaginal disks.
