HUMULIN 70/30 (70% human insulin isophane suspension and 30% human insulin injection [rDNA origin]) is a human insulin suspension. Human insulin is produced by recombinant DNA technology utilizing a non-pathogenic laboratory strain of Escherichia coli. HUMULIN 70/30 is a suspension of crystals produced from combining human insulin and protamine sulfate under appropriate conditions for crystal formation and mixing with human insulin injection. The amino acid sequence of HUMULIN 70/30 is identical to human insulin and has the empirical formula C257H383N65O77S6 with a molecular weight of 5808.
