Division 4 Additional instructions:F1F2
United Kingdom
- (a)
the experiment shall be carried out with two serum dilutions (1:5 and 1:10) in order to achieve optimal precipitation;
- (b)
if the precipitation diameter is too small with both dilutions, then the serum shall be further diluted;
- (c)
if the precipitation diameter in both dilutions is too large and faint, then a lower serum shall be chosen;
- (d)
the final concentration of the agarose shall be 0,8 %; that of the sera 5 and 10 % respectively;
- (e)
plot the measured diameters in the following coordinate system. The dilution of the antigen to be tested with the same diameter as the reference antigen is the working dilution.
