In Vitro Efficacy Testing Services for Acute Lung Injury

We provide robust and sensitive in vitro screening and characterization platforms for accelerating the discovery and screening of potential therapies for Acute Lung Injury (ALI). Our services offer comprehensive assay panels that enable the evaluation of drug candidates targeting key inflammatory and proteolytic pathways implicated in ALI. We focus on critical targets and proteins such as neutrophil elastase, pro-inflammatory cytokines, and endothelial barrier integrity that are central to the pathogenesis of ALI. Our platforms are designed to assess associated pathological processes, including inflammation, protease activity, and cellular injury, to facilitate the characterization of therapeutic efficacy.

We offer a diverse range of biochemical and cell-based in vitro assays to evaluate compound activity and mechanism of action in the context of Acute Lung Injury. Our testing methods include luminescent, fluorescent, and colorimetric assays, as well as substrate-specific enzymatic assays, to provide comprehensive insights into drug efficacy and target engagement. These platforms enable accurate quantification of molecular and cellular responses relevant to ALI pathology.

ATP as substrate: Used to measure cellular energy metabolism and viability, providing insights into cellular damage or protection in ALI models.

ATP assay: Quantifies cellular ATP levels as an indicator of cell viability, cytotoxicity, or metabolic activity under ALI-related conditions.

Chemiluminescent assay: Detects specific biomolecules or enzymatic activities with high sensitivity, useful for measuring low-abundance targets involved in ALI.

Dye assay (DAPI): Utilizes DAPI staining to assess cell viability, apoptosis, and nuclear morphology, relevant for detecting cell injury and death in ALI.

Elastin as substrate: Measures the activity of elastase enzymes, which are implicated in the degradation of lung tissue during ALI.

Fluorescence resonance energy transfer (FRET) assay: Enables sensitive detection of protease activity and protein-protein interactions central to ALI pathophysiology.

Fluorescent assay: Provides quantitative measurement of enzymatic activities, cellular health, or molecular markers through fluorescence readouts.

Methoxysuccinyl-Ala-Ala-Pro-Val-7-amino-4-methylcoumarin as substrate: Specific substrate for neutrophil elastase activity assays, critical for evaluating inhibitors in ALI.

Methoxysuccinyl-Ala-Ala-Pro-Val-p-nitroanilide as substrate: Used to assess protease activity, particularly elastase, for screening anti-proteolytic compounds.

Swelling assay: Evaluates changes in cell or tissue volume as a measure of barrier integrity and permeability, reflecting edema formation in ALI.

Our assays measure a range of pharmacological parameters that quantify compound potency, efficacy, and selectivity. These parameters, such as IC-50, MEC, and pKi, are essential for comparing candidate drugs and guiding lead optimization. Accurate measurement of these values helps prioritize the most promising therapies for further development.

IC-50: The concentration of a compound required to inhibit a specific biological or biochemical function by 50%, providing a standard measure of potency.

MEC (Minimum Effective Concentration): The lowest concentration of a drug that produces a measurable biological effect, important for assessing therapeutic threshold.

MED (Minimum Effective Dose): The smallest dose of a compound that elicits the desired biological response, informing dose selection for further studies.

MIC (Minimum Inhibitory Concentration): The lowest concentration of an agent that prevents detectable biological activity, critical for evaluating efficacy against target enzymes or cells.

pIC-50: The negative logarithm of the IC-50 value, allowing for easier comparison of compound potencies on a logarithmic scale.

pKi: The negative logarithm of the inhibition constant (Ki), reflecting the binding affinity of an inhibitor for its target and aiding in lead optimization.
