LEUKINE Powder for solution for injection Ref.[116018] Active ingredients: Sargramostim

Sargramostim is a glycosylated recombinant human granulocyte-macrophage colony-stimulating factor (rhu GM-CSF) produced by recombinant DNA technology in a yeast (S. cerevisiae) expression system. Sargramostim is a glycoprotein of 127 amino acids characterized by three primary molecular species having molecular masses of 19,500, 16,800 and 15,500 Daltons.

The amino acid sequence of sargramostim differs from the natural human GM-CSF by a substitution of leucine at position 23, and the carbohydrate moiety may be different from the native protein. Sargramostim differs from human GM-CSF by one amino acid at position 23, where leucine is substituted for arginine.

LEUKINE (sargramostim) for injection is supplied as a sterile, preservative-free, white lyophilized powder in a single-dose vial for subcutaneous or intravenous use. Reconstitute each single-dose vial with 1 mL of diluent (i.e., sterile water for injection or bacteriostatic water for injection). After reconstitution each single-dose vial contains 250 mcg/mL sargramostim and the inactive ingredients mannitol (40 mg), sucrose (10 mg), and tromethamine (1.21 mg) per mL with a pH range of 7.1 - 7.7 with a deliverable volume of 1 mL (250 mcg).
