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].

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
× = ×

The specific active calculator equation

Specific Active (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Active (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
