Description

General description

The SMC^® Human Phospho-Tau (T181) 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 SMCxPRO^® immunoassay systems detect analytes using Single Molecule Counting (SMC^®) technology.

Specificity

Species Reactivity:
Specificity was not tested.

Cross Reactivity:
Cross-reactivity was not tested.

Accuracy:

• Minimum of 5 serum samples spiked with average recovery of 97% with a range of 70-138%
• Minimum of 5 plasma samples spiked with average recovery of 97% with a range of 81-127%
• Minimum of 5 CSF samples spiked with average recovery of 108% with a range of 82-146%

Application

The sensitivity of the Single Molecule Counting (SMC^®) technology gives the SMC^® Human Phospho-Tau (T181) High Sensitivity Immunoassay Kit unparalleled performance in the quantification of Phospho-Tau (T181) in human serum, plasma, and CSF.

This new streamline kit has the following features including:

• Improved options for sample prep and incubation
• Lyophilization of the standard provides the kit at one storage condition
• Removal of a plate transfer step
• Increased reagent volumes to accommodate automation
• Validated to run on both SMCxPRO^® and Erenna
