title: Isolation, nucleotide sequence and expression of a cDNA encoding feline granulocyte colony-stimulating factor.
abstract: A cDNA encoding feline granulocyte colony stimulating factor (fG-CSF) was cloned from alveolar macrophages using the reverse transcriptase-polymerase chain reaction. The cDNA is 949 bp in length and encodes a predicted mature protein of 174 amino acids. Recombinant fG-CSF was expressed as a glutathione S-transferase fusion and purified by affinity chromatography. Biological activity of the recombinant protein was demonstrated using the murine myeloblastic cell line GNFS-60, which showed an ED50 for fG-CSF of approximately 2 ng/ml.
