Long-term exposure to heat, light, or moisture may reduce peptide stability and should be avoided
Inhibition of growth hormone action improves insulin sensitivity in liver IGF-1-deficient mice
We do not use any fillers in this process.
Importantly, Hinton and colleagues showed that human IgG2 variants harboring Fc fragments with amino acid substitutions that increase their binding affinity towards human FcRn at specifically pH 6.0, but not pH 7.4, had prolonged plasma half-lives in non-human primates (NHPs) [104]
Lyophilization, or freeze drying, removes water from the peptide and produces a dry powder that generally offers greater stability than liquid preparations (Clemmitt, 2024)
