1) a number of dilutions of the same dilution factor are desired. Example: You want to make a series of solutions with a repeating dilution factor of 2; in other words, the concentration of each diluted solution should be half that of the. dilution before it (such as 2 M, 1 M, 0.5 M, 0.25 M).

This is accomplished by making 1:40, 1:80, 1:160, etc. serial dilutions of all positives. The endpoint titer is the highest dilution that produces a 1+ positive reaction. Homogeneous patterns with peripheral accentuation are frequently found in sera from patients with SLE.

1/4 x 2/4 or 1/4 x 1/2 = 1/8 in 2nd tube By transferring 2 mL of dilution from one tube to a second tube containing 2 mL of saline, and continuing to do so, this is actually making a 1:2 serial dilution.

Hint: Begin by making a stock solution containing 100 mg/dL. Serial dilutions can be used to rapidly explore a wide range of concentrations. To make serial 2-fold dilutions, mix 1 mL of material with 1 mL of diluent. Take 1 mL of this 2-fold dilution and add 1 mL of diluent to make a 4-fold dilution.
