In Vitro Efficacy Testing Services for Uveitis

We provide robust and sensitive in vitro screening and characterization platforms for accelerating the discovery and screening of potential therapies for uveitis. Our services offer comprehensive evaluation of candidate molecules through advanced biochemical and cellular assays tailored for uveitis research. Key targets include pro-inflammatory cytokines, immune signaling proteins, and ocular inflammatory pathways implicated in uveitis pathology. We enable the assessment of anti-inflammatory efficacy, inhibition of pathological immune activation, and modulation of disease-associated molecular mechanisms.

Our platform utilizes a range of in vitro testing methods, including cell viability, enzymatic activity, protein binding, and molecular interaction assays. These methods are designed to provide robust and quantitative data to support early-stage drug discovery and mechanistic studies relevant to uveitis. By applying multiple assay types, we ensure comprehensive evaluation of therapeutic candidates.

ATP assay: Measures cellular viability and metabolic activity as an indicator of compound cytotoxicity or protective effects, crucial for assessing candidate safety and efficacy in ocular cell models.

Chemiluminescent assay: Quantifies specific biomolecules or enzymatic activities with high sensitivity, allowing detection of inflammatory mediators or pathway activation relevant to uveitis.

Peptide as substrate: Employs synthetic peptides to monitor protease activity or enzymatic modulation, enabling precise analysis of target-specific inhibition or activation.

Surface plasmon resonance assay: Evaluates real-time binding interactions between drug candidates and target proteins, providing kinetic and affinity data essential for lead optimization.

We measure a set of key pharmacological parameters that quantify compound potency, efficacy, and target engagement. These parameters provide critical insights into the therapeutic potential and mechanism of action of tested agents. Accurate determination of these values guides decision-making in drug development and candidate prioritization.

EC-50: The concentration of a compound required to achieve 50% of its maximal effect, indicating potency and guiding dose selection.

IC-50: The concentration of an inhibitor where the response or binding is reduced by half, used to assess inhibitory activity against disease-relevant targets.

Kd: The dissociation constant reflecting the binding affinity between a drug and its target protein, critical for understanding molecular interactions and optimizing compound design.

Recommended In Vitro Efficacy Tests

Janus Kinase 1

Janus Kinase 1 (JAK1) is implicated in inflammatory signaling pathways involved in uveitis. JAK1 testing is essential for evaluating potential drug candidates targeting this pathway. Our service utilizes an ATP assay with a peptide substrate to measure JAK1 kinase activity. The primary parameter assessed is IC-50, indicating compound potency in inhibiting JAK1, which is critical for identifying promising uveitis therapeutics.

Janus Kinase 2

Janus Kinase 2 (JAK2) is a key mediator in inflammatory pathways implicated in uveitis pathogenesis. JAK2 testing is crucial for evaluating potential drug candidates targeting ocular inflammation. Our service utilizes an ATP assay with peptide substrates to measure JAK2 activity, providing accurate determination of inhibitory potency via IC-50 values. This enables efficient screening and optimization of therapeutic compounds for uveitis drug development.

Peptidylprolyl Isomerase A

Peptidylprolyl Isomerase A (PPIA) modulates immune responses and inflammation in uveitis. Testing PPIA activity and expression is crucial for evaluating drug efficacy and mechanism of action in uveitis drug development. Key methods include ELISA, Western blot, and activity assays. Main parameters measured are PPIA protein levels, enzymatic activity, and modulation following drug treatment, enabling targeted and effective therapeutic strategies.

Protein Kinase C Theta

Protein Kinase C Theta (PKCθ) is crucial in T-cell activation, contributing to autoimmune inflammation seen in uveitis. PKCθ testing is vital for identifying novel drug candidates targeting immune pathways. Key methods include in vitro kinase assays, cell-based phosphorylation analysis, and Western blotting. Main parameters assessed are PKCθ activation/phosphorylation levels, downstream cytokine expression, and drug inhibition potency, enabling precise evaluation of therapeutic effects on uveitis-related immune responses.

Tumor Necrosis Factor

Tumor Necrosis Factor (TNF) is a key inflammatory mediator in uveitis. Accurate TNF testing is crucial for developing effective uveitis therapies. Our service employs chemiluminescent and surface plasmon resonance assays to assess drug-TNF interactions. We provide critical parameters, including dissociation constant (Kd) for binding affinity and half-maximal effective concentration (EC-50) for drug potency, supporting precise evaluation of candidate therapies.

Tyrosine Kinase 2

Tyrosine Kinase 2 (TYK2) is implicated in inflammatory pathways relevant to uveitis pathogenesis. TYK2 testing is crucial for developing targeted uveitis therapies. Our assay uses a peptide substrate and ATP assay to evaluate compound inhibition of TYK2 activity. The primary parameter measured is IC-50, indicating the concentration required for 50% inhibition, enabling precise assessment of drug candidate efficacy.
