Recombinant Mouse Betacellulin/BTC Protein Summary
Description |
A recombinant protein containing 80 amino residues corresponding to Betacellulin/BTC, which comprises the mature EGF homologous portion of the Betacellulin protein Source: E. coli Uniprot ID: Q05928 Amino Acid Sequence: DGNTTRTPET NGSLCGAPGE NCTGTTPRQK VKTHFSRCPK QYKHYCIHGR CRFVVDEQTP SCICEKGYFG ARCERVDLFY This lyophilized preparation is stable at 2-8 degrees C, but should be kept at -20 degrees C for long term storage, preferably desiccated. Upon reconstitution, the preparation is most stable at -20 to -80 degrees C, and can be stored for one week at 2-8 degrees C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20 degrees C to -80 degrees C. Avoid repeated freeze/thaw cycles. |
Details of Functionality |
Betacellulin/BTC protein is fully biologically active when compared to standard. The ED50 as determined by a cell proliferation assay using murine Balb/c 3T3 cells is less than 0.01 ng/ml, corresponding to a specific activity of > 1.0 x 10^8 IU/mg |

Background
Betacellulin (BTC) encoded by the BTC gene located on the chromosome 4, is a member of the EGF family that also includes EGF, TGF-alpha, Amphiregulin, HB-EGF, Epiregulin, Tomoregulin and the Neuregulins. BTC is expressed in most tissues including kidney, uterus, liver and pancreas. It is also present in body fluids, including serum, milk, and colostrum. Mouse BTC is expressed as a 178-amino acid precursor and the amino acid sequence of the mature form is 80 % identical with human BTC. Both human and mouse BTC exhibit significant overall similarity with other members of the EGF family. Recombinant murine Betacellulin is a heparin binding protein containing 80 amino acids residues.
