now
1 clean tube for master dilution is taken
this is our master dilution (1:10 )
now transfer this master .5ml to 1st nd 2nd rows
add saline .5ml fron 2nd row to 8th row
u have to tak .5ml saline in 1st row only
here dil will be 1:20 after adding antigen .5ml
from 2nd row .5ml from master +.5 saline form = 1ml which
