Escherichia coli. |
| Molecular Weight: |
Approximately 23.4 kDa, a homodimeric protein consisting of two 102 amino acid non-glycosylated polypeptide chains. |
| AA Sequence: |
ARLGARPCGL RELEVRVSEL GLGYASDETV LFRYCAGACE AAARVYDLGL RRLRQRRRLR RERVRAQPCC RPTAYEDEVS FLDAHSRYHT VHELSARECA CV |
| Purity: |
> 96% by SDS-PAGE and HPLC analyses. |
| Biological Activity: |
Fully biologically active when compared to standard. The biologically active as determined by its binding ability in a functional ELISA. |
| Physical Appearance: |
Sterile filtered white lyophilized (freeze-dried) powder. |
| Formulation: |
Lyophilized from a 0.2 μm filtered concentrated solution in 30 mM Citrate Sodium, pH4.2, 400 mM NaCl, with 0.02% Tween-20. |
| Endotoxin: |
Less than 1 EU/μg of rHuNeurturin as determined by LAL method. |
| Reconstitution: |
Centrifuge the vial briefly before opening to ensure that the contents settle at the bottom. Reconstitute in sterile distilled water to a concentration of 0.5 mg/mL. Divide the resulting stock solution into working aliquots and store them at or below -20°C. For further dilutions, use appropriate buffered solutions. |
| Stability & Storage: |
Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
12 months from date of receipt, -20 to -70°C as supplied.
1 month, 2 to 8°C under sterile conditions after reconstitution.
3 months, -20 to -70°C under sterile conditions after reconstitution. |
