Antivenom
An antidote produced by injecting trace amounts of toxin into large animals to induce antibody production, then extracting and purifying antibody fragments from the blood. Production cycles are long, costs are high, and coverage is limited.
Timeline (last 90 days)
The efficacy of antivenom depends on whether antibodies can specifically bind and neutralize key epitopes of the toxin, thereby preventing the toxin from binding to human targets (such as ion channels).
Antivenom is a biological product containing polyclonal antibodies against components of a specific snake or scorpion venom, rather than a small-molecule drug produced through chemical synthesis.
The traditional antivenom production process includes repeatedly immunizing large animals such as horses or sheep with trace amounts of venom, collecting plasma, purification, and enzymatic cleavage (such as preparing F(ab')2 fragments).
One antivenom can usually only neutralize the toxins of a specific species or closely related species, and given the more than a thousand scorpion species worldwide, its coverage is extremely limited.
The traditional antivenom production process involves injecting trace amounts of toxin into large animals (such as horses or sheep), extracting and purifying antibody fragments after they produce antibodies, and the entire cycle often takes months.
Animal antibodies are heterologous proteins to the human body and may trigger serum sickness or allergic reactions.
Traditional antivenom relies on animal immunization and suffers from batch variation, inconvenient storage, and allergy risks.
