# Assay

## Overview

The Assay widget category provides specialized tools for conducting and analyzing common laboratory assays directly within Labii's ELN and LIMS. These widgets cover key assay methodologies — from dose-response modeling to ELISA-based detection and quantification — eliminating the need for external tools like Excel or GraphPad. Whether you are determining compound potency, detecting the presence of a target analyte, or quantifying protein concentrations from a standard curve, these widgets provide a structured, reproducible workflow in a single platform. All widgets support the standard 96-well plate format and are designed to reduce manual effort while maintaining data integrity and traceability.

## Widgets

* [Dose Response Curve](/widgets/section-widgets/biology/assay/dose-response-curve.md) - Fit and visualize dose-response relationships from plate data
* [ELISA Qualitative](/widgets/section-widgets/biology/assay/elisa-qualitative.md) - Determine analyte presence or absence from 96-well ELISA plates
* [ELISA Standard Curve](/widgets/section-widgets/biology/assay/elisa-standard-curve.md) - Perform standard curve fitting and concentration prediction for ELISA data
