# 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](https://docs.labii.com/widgets/section-widgets/biology/assay/dose-response-curve) - Fit and visualize dose-response relationships from plate data * [ELISA Qualitative](https://docs.labii.com/widgets/section-widgets/biology/assay/elisa-qualitative) - Determine analyte presence or absence from 96-well ELISA plates * [ELISA Standard Curve](https://docs.labii.com/widgets/section-widgets/biology/assay/elisa-standard-curve) - Perform standard curve fitting and concentration prediction for ELISA data --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.labii.com/widgets/section-widgets/biology/assay.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
