This ELISA kit provides quantitative measurement of Ferritin Light Chain (FTL) in human samples, supporting research into iron storage, metabolism, and ferritin assembly. Because FTL circulating levels span a broad dynamic range — from low picogram levels in iron-deficient states to elevated concentrations in inflammatory or iron-overload conditions — this kit is designed to capture biologically meaningful differences across diverse experimental models.
Detection Range: The 15.6–1000 pg/mL range accommodates the low baseline FTL concentrations found in cell culture supernates and captures elevated levels seen in serum or plasma from iron-overload or inflammatory conditions, though samples from hemochromatosis or macrophage activation models may require dilution.
Sensitivity: At 7.8 pg/mL, the kit detects FTL in conditioned media from hepatocytes or macrophages under basal culture conditions, where secreted ferritin levels can be minimal prior to iron or cytokine stimulation.
Sample Compatibility: Validation across serum, plasma, cell culture supernates, and tissue homogenates enables researchers to correlate circulating FTL with intracellular ferritin pools in matched tissue or cell lysate samples — critical for dissecting iron sequestration dynamics at systemic and cellular levels.
Assay Efficiency: The 1–5 hour protocol and 50–100 µL sample volume accommodate limited-volume primary hepatocyte or monocyte-derived macrophage cultures without pooling.
This kit is well-suited for studies of hereditary hyperferritinemia-cataract syndrome, iron-deficiency anemia, and inflammation-driven ferritin dysregulation.
