Betacellulin Active Protein | BTC active protein

Recombinant Human Betacellulin

Purity
Greater than 97.0% as determined by(a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.
Synonyms
Betacellulin; Recombinant Human Betacellulin; BTC Human; Betacellulin Human Recombinant; BTC active protein
Ordering
For Research Use Only!
Host
E Coli
Purity/Purification
Greater than 97.0% as determined by(a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.
Form/Format
The Betacellulin Human Recombinant was lyophilized after extensive dialysis against 20mM phosphate buffer pH-7.4.
Sterile Filtered White lyophilized (freeze-dried) powder.
Sequence
The sequence of the first five N-terminal amino acids was determined and was found to be Asp-Gly-Asn-Ser-Thr
Sequence Length
178
Solubility
It is recommended to reconstitute the lyophilized BTC Human in sterile 18M Omega -cm H2O not less than 100 ug/ml, which can then be further diluted to other aqueous solutions.
Protein Content
Protein quantitation was carried out by two independent methods1. UV spectroscopy at 280 nm using the absorbency value of 0.69 as the extinction coefficient for a 0.1% (1mg/ml) solution. This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics). 2. Analysis by RP-HPLC, using a calibrated solution of BTC as a Reference Standard.
Biological Activity
The ED50, calculated by the dose-dependant proliferation of murine BALBC 3T3 cells (measured by 3H-thymidine uptake) is < 0.05 ng/ml. corresponding to a Specific Activity of >20,000,000IU/mg.
Preparation and Storage
Lyophilized Betacellulin Human Recombinant although stable at room temperature for 3 weeks, should be stored desiccated below -18 degree C. Upon reconstitution BTC Human should be stored at 4 degree C between 2-7 days and for future use below -18 degree C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles.
Related Product Information for BTC active protein
Description: Betacellulin Human Recombinant produced in E Coli is a single, non-glycosylated, polypeptide chain containing 80 amino acids and having a molecular mass of 9 kDa. Betacellulin Human Recombinant is purified by proprietary chromatographic techniques.

Introduction: Btc is a potent mitogen for retinal pigment epithelial cells and vascular smooth muscle cells. The effects of betacellulin are probably mediated by the egf receptor and other related receptors.

NCBI Description

The protein encoded by this gene is a member of the EGF family of growth factors. It is synthesized primarily as a transmembrane precursor, which is then processed to mature molecule by proteolytic events. This protein is a ligand for the EGF receptor. [provided by RefSeq, Jul 2008]

Product Notes

The BTC btc (Catalog #AAA142207) is an Active Protein produced from E Coli and is intended for research purposes only. The product is available for immediate purchase. The amino acid sequence is listed below: The sequence of the first five N-terminal amino acids was determined and was found to be Asp-Gly-As n-Ser-Thr. It is sometimes possible for the material contained within the vial of "Betacellulin, Active Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.
