The characteristics of the biotech products C1. Biotech products are usually protein-based drugs 2. Mimic endogenous components with higher efficiency and lower side effects compare with small molecule drugs; 3. Intrinsic instability multifaceted metabolic o properties, and limited gastrointestinal absorption sually injections available 4. The biological half-life is usually very short results in very short duration11 The characteristics of the biotech products • 1．Biotech products are usually protein-based drugs • 2．Mimic endogenous components with higher efficiency and lower side effects compare with small molecule drugs; • 3 ． Intrinsic instability, multifaceted metabolic properties, and limited gastrointestinal absorption; Usually injections available • 4．The biological half-life is usually very short, results in very short duration
