IL-3 Protein, Human, Recombinant (His & Avi)

Catalog No. TMPK-00031

Interleukin 3 is a pleiotropic factor produced primarily by activated T cells that can stimulate the proliferation and differentiation of pluripotent hematopoietic stem cells as well as various lineage committed progenitors. This CSF induces granulocytes, macrophages, mast cells, stem cells, erythroid cells, eosinophils and megakaryocytes. IL-3 Protein, Human, Recombinant (His & Avi) is expressed in E. coli expression system with N-His-Avi tag. The predicted molecular weight is 16.9 kDa and the accession number is P08700.

Protein Purity	> 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC
Molecular Weight	16.9 kDa (predicted) same as Tris-Bis PAGE result.
Endotoxin	< 1 EU/μg by the LAL method.
Formulation	Lyophilized from a solution filtered through a 0.22 μm filter, containing PBS (pH 7.4). Typically, 8% trehalose is incorporated as a protective agent before lyophilization.
Reconstitution	Reconstitute the lyophilized protein in distilled water. The product concentration should not be less than 100 μg/ml. Before opening, centrifuge the tube to collect powder at the bottom. After adding the reconstitution buffer, avoid vortexing or pipetting for mixing.
Stability & Storage	It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots.
Shipping	In general, Lyophilized powders are shipping with blue ice.
