Collagenases & Gelatinases
Collagenases & Gelatinases
Quantitative assays for matrix metalloproteinase activity — measure collagen and gelatin degradation to evaluate anti-wrinkle and skin-firming ingredient efficacy.
Matrix Metalloproteinases in Skin Aging
Collagenases (MMP-1, MMP-8, MMP-13) and gelatinases (MMP-2, MMP-9) are zinc-dependent endopeptidases that degrade the extracellular matrix proteins responsible for skin structural integrity. UV exposure, oxidative stress, and chronological aging upregulate MMP expression in dermal fibroblasts, leading to collagen fragmentation and wrinkle formation. Enzo Life Sciences provides sensitive fluorometric and ELISA-based assay kits for measuring MMP activity, quantifying collagen degradation products, and screening potential MMP inhibitors in cosmetic formulations.
MMP-1 (Collagenase-1) Activity
Fluorometric assay kits for measuring interstitial collagenase activity in fibroblast culture supernatants. MMP-1 is the primary enzyme responsible for initiating type I collagen degradation in photoaged skin. Screen anti-aging actives for collagenase inhibition at picomolar sensitivity.
MMP-2 & MMP-9 (Gelatinases)
Quantitative gelatinase activity assays using fluorescein-labeled gelatin substrates. MMP-2 (gelatinase A) and MMP-9 (gelatinase B) further degrade collagen fragments generated by collagenases, amplifying matrix breakdown. Detect gelatinase activity in cell lysates, conditioned media, and tissue extracts.
Collagen Degradation Markers
ELISA kits for collagen type I C-telopeptide (CTX-I), collagen type III N-terminal propeptide, and hydroxyproline — degradation products that serve as quantitative biomarkers of collagenolysis. Monitor treatment effects on collagen turnover in reconstructed skin models.
TIMP & MMP Inhibitor Screening
Tools for evaluating tissue inhibitors of metalloproteinases (TIMP-1, TIMP-2) and screening natural or synthetic MMP inhibitors. Measure the MMP/TIMP balance — a key determinant of net collagen degradation in aging skin.
