| Formulation |
The protein was lyophilized from a 0.2 µm filtered solution containing 1X PBS, pH 8.0. If you have any concerns or special requirements, please confirm with us. |
| Features & Benefits |
Endotoxin: <0.1 EU per 1 μg of the protein by the LAL method. |
| Molecular weight |
15.9 kDa |
| Usage notes |
Always centrifuge tubes before opening. It is recommended to reconstitute the lyophilized Human IL-4 Protein, His tag (Animal-Free) using the buffer we provided not less than 100 µg/ml, which can then be further diluted to other aqueous solutions. |
| Storage instructions |
Lyophilized protein should be stored at -20°C for 1 year.
Upon reconstitution, store at 2°C to 8°C for up to 1 week. Further dilute in a buffer containing a carrier protein or stabilizer (e.g. 0.1%
BSA, 10%FBS, 5%HSA or 5% trehalose solution), protein aliquots should be stored at -20°C or -80°C for 3-6 months. Avoid repeated freeze/thaw cycles. |
