Interleukin-4 (IL-4) is produced by a range of bovine cells, including T and B lymphocytes, monocytes and macrophages, and plays an important role in the immune response.
- Target Species
- Product Form
- Purified recombinant protein - lyophilized
- Reconstitute with 0.5 ml distilled water. Care should be taken during reconstitution as the protein may appear as a film at the bottom of the vial. Bio-Rad recommend that the vial is gently mixed after reconstitution.
Further dilutions should be made in a buffer containing carrier protein.
- Recombinant protein expressed in Pichia pastoris
- Buffer Solution
- Phosphate buffered saline
- Preservative Stabilisers
- None present
- >95% by SDS PAGE analysis
- Approx. Protein Concentrations
- Total protein concentration 0.04 mg/ml after reconstitution
- Protein Molecular Weight
- 12.6 kDa
- Prior to reconstitution store at +4oC.
Following reconstitution store at -70oC.
Storage in frost-free freezers is not recommended. Avoid repeated freezing and thawing as this may denature the protein. Should this product contain a precipitate we recommend microcentrifugation before use.
