Measuring IgG Titer: Need for Real-Time Results, Customization and High Comparability to HPLC

Answer
The Cedex Bio Analyzers provide selectable test protocols for automated IgG determination with high sensitivity down to 10 mg/L and up to 8 g/L. Using the instruments on-board capability for further pre-dilution of the sample, the range can be extended to 40 g/L (when taking advantage of this feature, checking the validity of the results for your individual sample matrix is recommended).
The IgG assay requires only 2-25 µL of sample (for sensitive or high range). A 100 µL sample volume is sufficient to perform the IgG assay and also additional assays from the test menu, such as: glucose, lactate, glutamine, LDH, NH3, etc.
