Description

General description

The human Tau family of microtubule-associated neuronal proteins has been rigorously studied in the context of normal and aberrant neurobiology. While typically involved in the stability of axonal microtubules, Tau proteins can also play a role in neurodegenerative diseases such as Alzheimer′s Disease (AD) and frontotemporal dementia (FTD) if they aberrantly misfold and accumulate in the brain. There is significant interest in studying the level of Tau proteins in both the central nervous system as well as in circulation, and the new SMC^® Human Total-Tau High Sensitivity Immunoassay Kit enables researchers to take advantage of the Single Molecule Counting ultrasensitive immunoassay technology to perform accurately and sensitive measurements in human cerebrospinal fluid (CSF), plasma, and serum samples, toward making important discoveries about the role of Tau protein in neurodegenerative disease mechanisms.
The SMC^® Human Total Tau High Sensitivity Immunoassay Kit contains all reagents required to perform the assay. This assay takes advantage of a standard immunoassay workflow configured in a standard plate format. Assay protocols are similar to existing sandwich ELISA methods with two key differences:
1) Elution buffer disrupts the sandwich, separating the labeled detection antibody for quantification.
2) The Erenna and TM="SMCxPRO"] immunoassay systems detect analytes using Single Molecule Counting SMC^® technology.

Specificity

Specificity to the following species samples were tested with the follow results:

• Non Human Primate – 50%
• Mouse – 100%
• Rat – 100%
• Canine – 100%
• Feline – 75%

Application

The sensitivity of the Single Molecule Counting SCM technology gives the SCM Human Total Tau High Sensitivity Immunoassay Kit unparalleled performance in the quantification of Human Total Tau in human serum, plasma, and CSF.

This new streamline kit has the following features:

• Improved options for sample prep and incubation
• Lyophilization protein standard for uniform shipping and storage condition
• Increased reagent volumes to accommodate automation
• Able to achieve assay specifications on both SMCxPRO^® and Erenna.
