3. Invitrogen Proprietary & Confidential 3. BASIC PROTOCOL  50 L of water was passed through a Filta-max™ filter.  Processed parasite enumeration using Method 1623  Immunomagnetic separation (IMS) carried out using Dynabeads  -GC Combo Kit  Oocysts enumerated using immunofluorescent antibodies (IFA),  PCR-RFLP analysis. Xiao et al.  DNA extracted Ruecker et al  All positive reactions digested with Ssp I, Vsp I and Dde I  Fractionated by 2% agarose gel electrophoresis and visualized  PCR products excised from the electrophoresis gel,  Purified and sequenced (if necessary)
