Biological Activity
The ED50 is <0.4 ng/mL as measured by TF-1 cells, corresponding to a specific activity of >2.5 × 106 units/mg.

Appearance
Lyophilized powder.

Formulation
Lyophilized after extensive dialysis against 20 mM Tris, pH 8.5.

Endotoxin Level
<0.2 EU/μg, determined by LAL method.

Reconstitution
Reconstitute the lyophilized recombinant Rat Interleukin-5 (rRtIL-5) to 100 µg/mL using ddH2O.

Storage & Stability
Lyophilized recombinant Rat Interleukin-5 (rRtIL-5) is stored at -20°C. After reconstitution, it is stable at 4°C for 2 weeks or -20°C for longer. It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Shipping
Room temperature in continental US; may vary elsewhere.

Background
Interleukin-5 (IL-5) is a T-cell derived cytokine which stimulates eosinophil production and activation in human, mice and sheep. IL-5 is active as a growth factor for mouse but not human B cells. The role of IL-5 on ruminant B cells has not been clearly defined. By hybridisation with human IL-5 cDNA, the ovine IL-5 gene is isolated from a liver genomic library. The IL-5 cDNA is obtained by reverse-transcriptase PCR using primers designed from the 5' and 3' coding sequence derived from the ovine IL-5 gene. The sequences of the cDNA shows that there is 79% and 73% nucleotide homology with the human and mouse sequences. The ovine IL-5 cDNA encodes a protein of 132 amino acids and the level of amino acid homology with human and mouse IL-5 is 64% and 56%, respectively. Two cysteine residues are conserved in ovine, human and mouse IL-5. There are two potential N-linked glycoyslation sites in ovine IL-5[1].
