Basic Procedures for Facilitation,ecal B cell activity. Immunoglobulins (Ig) and free light chains (FLC) which are both secreted by terminally differentiated B cells can be detected in the cerebrospinal fluid (CSF). As these proteins are not only present in the CSF in case of intrathecal inflammation, but also derive from blood by d

Stable isotope-labeled Aβ peptides are used as internal standards, enabling absolute quantification. A high-resolution quadrupole-Orbitrap hybrid instrument was used for measurements. The method allows quanti

From this broad definition, it follows that validations can be made in many different fields with quite different implications. When talking about validation, it is therefore important to specify the subject under scrutiny and in this cha

The development of a bead-based single molecule array (Simoa) assay for the neurofilament light chain provided a substantial improvement in sensitivity compared with conventional ELISA or electrochemiluminescence-based assays allowing reliable qua
