摘要
The absence of Fc receptor binding, cost-effective production potential in large quantities in pure form, and better storage stability of avian immunoglobulin (IgY) advocate its therapeutic use as anti-snake venom (ASV). This study develops pure anti-neurotoxin (ANT- IgY) by immunizing White Leghorn hens with Cobra and Krait venoms for demonstrating antigen-antibody binding in vitro/in vivo. The purified IgY from immunized egg-yolk showed immunoprecipitation in Ouchterlony's Double Diffusion (ODD) experiment. For characterizing ANT-IgY distribution and clearance pattern, the study utilized an enzyme-linked immunosorbent assay (ELISA) in serum at different intervals following intravenous (IV) administration. The Kinetica 5.1 software estimated pharmacokinetic parameters, including half-life. The IgY showed a time-dependent elimination through the intestinal route in fecal matter. After conjugating with a fluorochrome-Vivotag-750S, injected the purified ANT-IgY intravenously into the healthy mice. Subsequently, captured live-animal images to demonstrate the distribution and elimination profile of the molecule. Intramuscular injection of fluorochrome-tagged venom created the envenomed mice model. The live-animal images demonstrated the quick mobilization of venom into vital tissues. Intravenous administration of tagged ANT-IgY in the envenomed model showed the movement of ASV to the tissues venom traffics. The observed pharmacological benefit promise scope of ASV-IgY for therapeutic use.
