Assays

This assay characterizes the glycosylation profile of biological samples by analyzing the composition, structure, and abundance of glycan moieties attached to proteins or other biomolecules. Standard glycosylation analysis workflows typically involve sample preparation steps such as enzymatic release of N-linked glycans (e.g., via PNGase F treatment), followed by labeling or derivatization and separation using chromatographic or electrophoretic techniques (such as HPLC, UHPLC, or capillary ...

This assay employs an enzyme-linked immunosorbent assay (ELISA) methodology to quantitatively detect and measure specific analytes (such as proteins, antibodies, or other biomolecules) in biological samples. The technique utilizes antibody-antigen interactions coupled with enzymatic signal amplification to generate colorimetric or fluorometric readouts proportional to analyte concentration. Sample preparation, incubation conditions, wash steps, and detection reagents are performed according to ...

Antibody-dependent complement deposition measures complement protein binding following antibody interaction. The assay detects complement activation as an indicator of antibody-mediated immune function. Input: Antibody-coated target cells Output: Complement deposition measurement or fluorescence data file.

Antibody-dependent cellular phagocytosis measures immune cell uptake of antibody-coated targets. The assay quantifies phagocytic activity as an indicator of antibody function and cellular response. Input: Antibody-treated target cells and effector cells Output: Phagocytosis data file (e.g., fluorescence or imaging-based readouts).

Antibody-dependent neutrophil phagocytosis evaluates antibody-mediated uptake of targets by neutrophils. It measures fluorescence or imaging-based signals to assess innate immune activity. Input: Antibody-labeled target cells and neutrophils Output: Phagocytosis data file indicating neutrophil uptake efficiency.

This assay evaluates the ability of bacterial populations to survive under defined restrictive conditions, quantifying survivability metrics through linked experimental data to assess bacterial viability and growth inhibition. The methodology incorporates controlled exposure of bacterial cultures to restrictive agents or environmental stressors, with outcomes measured via standardized enumeration or optical density-based approaches to determine survival rates relative to untreated controls. Results ...

Antibody-dependent NK cell activation measures natural killer (NK) cell responses triggered by antibody-coated targets. The assay detects cytokine release or surface marker expression as indicators of immune activation. Input: Antibody-treated target cells and NK effector cells Output: Cytometric or fluorescence data representing NK activation levels.
