Human NRG1 B1 Bioactive Protein Product Attributes
Product Type: Bioactive Protein
Recombinant NRG1 B1 based upon sequence from Human
Host: QP10798 protein expressed in E. Coli.
Available Tags: Untagged
Protein Construction: A cDNA sequence encoding the sequence of NRG1 B1 was constructred and used to recombinantly synthesize the protein.
Recommended Applications: Bioactive
Recommended Reconstitution Instructions: It is recommended to reconstitute the lyophilized NRG1-B1 in sterile 18M-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.
Bioactivity Data: The ED50 was determined by the dose-dependent stimulation of the proliferation of human MCF-7 cells is less than 0.5ng/ml, corresponding to a specific activity of >2.0x10^6 units/mg.
Amino Acid Sequence: SHLVKCAEKE KTFCVNGGEC FMVKDLSNPS RYLCKCPNEF TGDRCQNYVM ASFYKHLGIE FMEAE
Purity: Greater than 97.0% as determined by:(a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.
Endotoxin Levels: < 1.0 EU per ug protein as determined by the LAL method.
Buffer: Lyophilized from a 0.2um filtered solution in 1xPBS, pH 7.4 and 5% trehalose.
Storage Conditions: Lyophilized NRG1-B1 although stable at room temperature for 3 weeks, should be stored desiccated below -18Â°C. Upon reconstitution NRG1-B1 should be stored at 4Â°C between 2-7 days and for future use below -18Â°C. Please prevent freeze-thaw cycles.
Physical Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.
