Category
| Source | Mouse LIF, amino acids (Ser24-Phe203) (Accession# NP_032527.1), was expressed in E. coli. |
|---|---|
| Molecular Mass | This 180 amino acid protein has a predicted molecular mass of approximately 20 kD. The protein migrates at approximately 20 kD in DTT-reducing conditions and approximately 18 kD in non-reducing condition by SDS-PAGE. The predicted N-terminal amino acid is Ser. |
| Purity | >98%, as determined by Coomassie stained SDS-PAGE. |
| Formulation | 0.22 µm filtered protein solution is in PBS, pH 7.4. |
| Endotoxin Level | Less than 0.1 EU per µg of protein as determined by the LAL method. |
| Concentration | 10 and 25 µg sizes are bottled at 200 µg/mL. 100 µg size and larger sizes are lot-specific and bottled at the concentration indicated on the vial. To obtain lot-specific concentration and expiration, please enter the lot number in our Certificate of Analysis online tool. |
| Storage & Handling | Unopened vial can be stored between 2°C and 8°C for up to 2 weeks, at -20°C for up to six months, or at -70°C or colder until the expiration date. For maximum results, quick spin vial prior to opening. The protein can be aliquoted and stored at -20°C or colder. Stock solutions can also be prepared at 50 - 100 µg/mL in appropriate sterile buffer, carrier protein such as 0.2 - 1% BSA or HSA can be added when preparing the stock solution. Aliquots can be stored between 2°C and 8°C for up to one week and stored at -20°C or colder for up to 3 months. Avoid repeated freeze/thaw cycles. |
Unless otherwise stated, the minimum order amount is USD 1,000.
For orders below USD 1,000, an additional handling fee may apply, or we may arrange local delivery / local handover where available.
