The cDNA coding for Granulocyte macrophage colony stimulating factor (GM-CSF) from LPS activated macrophages was amplified using reverse transcriptase polymerase chain reaction (RT-PCR), which was then cloned into the pCNDA vector and sequenced. The amplified bovine GM-CSF cDNA was 755 bp length without the secretory signal peptide sequence. The ORF coded for 143 amino acids with a molecular weight of 16200 Da and was 99 percent identical to Bos taurus and Bubalus bubalis, respectively. The phylogenetic study found that the GM-CSF sequences of swine and horse are the most distinct from those of buffalo, sheep, goat, and deer.
