All testing parameters and data are stored automatically on the system within password protected directories and files. Microbial Testing System Bacteria can be labeled with antibody-based fluorescent tags designed to target a specific genus or species of organism. Additionally, fluorescent stains are available that will label all the bacteria species within a sample. Large sample volumes or background issues are addressed with antibody and immunomagnetic bead or filter capture methods. AATI's methods and protocols are provided for your sample matrix to assist your development of in-house testing procedures.
Additional methods are being release monthly.
This single-file flow is achieved by using an effect known as hydrodynamic focusing. The objects, which are typically suspended in a fluid such as water or buffer solution, are delivered to the sheath flow cell via a sample delivery tube. The exit of a continuous, but small, amount of this fluid serves to deliver the objects into the sheath flow cell. Objects, such as bacteria, which have been labeled with fluorescent dyes, can be detected because of the brief fluorescence bursts that occur when each one passes through the beam. Enumeration is then simply a matter of accumulating the number of these bursts.
