THE METHOD OF COMBINING ANTIGEN OF LEISHMANIA INFANTUM TO LATEX BEAD AND THE METHOD OF DIAGNOSING LEISHMANIASIS

摘要

PURPOSE: A method for binding Leishmania infantum antigen to latex beads is provided to enable simple and cheap diagnosis without expensive equipment. CONSTITUTION: A method for binding Leishmania infantum(ATCC 50134) antigen to latex beads comprises: a step of the Leishmania infantum antigen in 45mM~55mM HEPES(4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid) and 145-155mM NaCl buffer in a concentration of 1.45mg/ml-1.55mg/ml; a step of reacting the latex beads into the diluted antigen at 35-39°C for 0.5-1.5 hours and then reacting at 3-5°C for 8-12 hours; a step of centrifuging the reacted antigen at 5,000rpm-7000rpm for 15-25 minutes; and a step of treating 10% BSA(Bovine Albumin Serum) for 2.5-3.5 hours.
