Polygalacturonic acid
Based on 1 Customer Validation
Polygalacturonic acid (Galacturonic acid polymer) is transparent colloid, is a major component of the cell wall. Polygalacturonic acid can be used to prepare silver nanoparticles (AgNPs), as an antioxidant and anti-inflammatory that protect cells from destructive effect of elevated ROS and accelerate wound healing. Polygalacturonic acid nanoparticles also displays anti-bacterial activity.

Biological Activity
제품 설명
In Vitro
Polygalacturonic acid can be used to format a durable hydrogel, to prolong the effect of drugs. Polygalacturonic acid hydrogel/hyaluronate, conjugated Ibuprofen (HY-78131) for example, prevents epidural fibrosis, the severe scar tissue adhesion of laminectomized male adult rats, and increases the efficiency of local inflammation control and reduces the side-effect of Ibuprofen[1].
Polygalacturonic acid hydrogel/hyaluronate (PGA-HA) (2%, 200 μL; 24 h) shows low cytotoxicity on L929 fibroblasts[1].
Polygalacturonic acid (PGA) preparing (Ag-PGA/HA)-PVA nanoparticles, shows anti-bacterial activity against gram-positive bacterial strains; Bacillus Subtilis and Staphylococcus Aureus, as well as gram-negative bacterial strain; Escherichia Coli[2].

ROS/oxidative-stress fluorescent staining
ROS/oxidative-stress fluorescent staining uses cell-permeant fluorogenic probes that become fluorescent after oxidation inside cells or tissues; commonly used examples include DCFH-DA/DCFDA for broad cellular oxidant detection, DHE for superoxide-related signal detection, MitoSOX for mitochondrial superoxide-related signal detection, and CellROX probes for oxidative-stress-associated fluorescence readouts. The assay detects probe oxidation rather than a single ROS species unless the probe and analysis method have been chemically validated for that species. DCFH-DA enters cells, is deacetylated by intracellular esterases to DCFH, and produces fluorescent DCF after oxidation, so the readout is used as an operational measure of total cellular oxidative stress rather than a species-specific ROS measurement. DHE and MitoSOX can report superoxide-related oxidation, but red fluorescence alone can include non-specific ethidium-like oxidation products; HPLC or optimized spectral approaches are

Research Protocol for Inflammation-related Diseases
The NLRP3 inflammasome is a cytosolic innate immune signaling platform that integrates priming signals and danger-signal activation to promote caspase-1 activation, maturation of IL-1β and IL-18, and gasdermin D-mediated pyroptotic cell death. The core experimental logic is to determine whether inflammatory disease phenotypes are driven by increased NLRP3 expression, ASC-containing inflammasome assembly, caspase-1 cleavage, GSDMD cleavage, and extracellular release of IL-1β/IL-18 rather than by nonspecific cell injury alone. The pathway is strongly linked to inflammation-related disease phenotypes because monosodium urate crystals activate NALP3/NLRP3 inflammasome signaling in gout-like crystal inflammation, cholesterol crystals activate NLRP3 inflammasomes in atherogenesis models, and DSS-induced intestinal inflammation has been reported to involve NLRP3 inflammasome activity. However, experimental colitis studies also show context-dependent protective effects of NLRP3 inflammasome co

Cell-Exclusion Zone Migration Assay
The Cell-Exclusion Zone (CEZ) migration assay is an in vitro 2D cell migration method in which a defined cell-free area is created using removable physical barriers such as silicone stoppers, allowing cells to be seeded around the barrier and subsequently migrate into the cleared zone after barrier removal. This approach enables quantification of collective cell migration by monitoring repopulation of the initially cell-free region over time using microscopy-based imaging. Compared with scratch-based wound healing assays, barrier-based exclusion methods are designed to avoid mechanical damage to the extracellular matrix and reduce injury-induced effects on boundary cells, thereby improving interpretability of migration behavior in vitro. The assay readout is typically the progressive reduction in the cell-free area or the number of cells invading the exclusion zone, reflecting coordinated cell motility relevant to physiological processes such as wound healing, epithelial repair, and ca
