Abstract

Μία μέθοδος και ένα κυτίο εξετάσεως χρήσιμο για μια μεγάλη ποικιλία συστημάτων ανοσοποιητικοιύ προσδιορισμού. Δίδεται μια μέθοδος παραγωγής αντιδραστηρίων κολλοειδούς μετάλλου που περιέχουν τεμαχίδια κολλοειδούς μετάλλου ενός προεπιλεγέντος μεγέθους. Ενα διάλυμα το οποίο περιέχει μέταλλο ανάγεται υπό βελτιστοποιημένας συνθήκας ρΗ δια να παραχθούν τεμαχίδια κολλοειδούς μετάλλου εντός προεπιλεγέντος μεγέθους. Τα τεμαχίδια επενδύονται με μια ένωση συζεύξεως και ακολούθως συνδέονται με ένα τουλάχιστον επιλεγμένο ανοσοχημικά ικανό προς αντίδραση συστατικό. Τεμαχίδια τα οποία έχουν διάφορες ανασοχημικές ιδιότητες (εξειδικεύσεις) αναμιγνύονται επίσης προς παραγωγήν αντιδραστηρίων που έχουν πολλές επιλεγείσες ανασοχημικές εξειδικεύσεις (ιδιότητες). ω
