Abstract
A direct enzyme-linked immunosorbent assay (ELISA) using an avidin-biotin complex (ABC) system for the identification of human blood is described. In this ELISA-ABC method, in which biotin-labeled goat IgG antibody against human HbA0 was used, it was possible clearly to distinguish human blood from the blood of other species, including that of Japanese monkeys. It took about 3 h to obtain the results. Human Hb concentrations ranging from 22 ng to 169 μg produced a positive reaction, and the minimum detection limit in terms of the highest possible dilution of human blood was 1∶640,000. Beschreibung einer direkten ELISA-Methode unter Verwendung des Avidin-Biotin-Complexes zur Identifizierung winziger Mengen menschlichen Blutes. In dieser ELISA-ABC-Methode wurde ein Biotin-gebundener IgG-Antikörper (Ziege) gegen Human-HbA0 verwandt. Mit dieser Methode war menschliches Blut von dem Blut japanischer Affen und anderer Tiere sehr leicht unterscheidbar. Positive Reaktionen wurden nach einer Untersuchungszeit von etwa 3 Std. gewonnen. Minimale Hämoglobin-Präparationen zwischen 22 ng und 169 μg erwiesen sich als ausreichend, um eindeutige positive Reaktionen zu erzeugen. Der Test reagierte bis zu einer Blutverdünnung von 1∶640.000-fach positiv.This publication has 16 references indexed in Scilit:
