Ceramide ELISA Kit

SKU: orb1881455

Description

Ceramides are key bioactive sphingolipids involved in apoptosis, inflammation, and cellular stress signalling, with established roles in cancer, metabolic disease, and neurodegeneration. Accurate measurement of ceramide levels is essential for studying lipid signalling pathways and disease mechanisms. This Ceramide ELISA kit uses a competitive ELISA assay to enable sensitive and reliable ceramide quantification in serum, plasma, cell lysates, and tissue samples. The assay offers high specificity with minimal cross-reactivity to related lipids, ensuring robust and reproducible results. Ideal for sphingolipid analysis, biomarker research, and drug discovery, this ceramide assay supports both routine laboratory use and high-throughput workflows.

Procedure & Performance

• Assay Principle:
  This kit is based on a competitive ELISA detection method. The microtiter plate is pre-coated with target antigen. During the assay, the target antigen in the sample or standard competes with the immobilized target for binding sites on the biotinylated detection antibody specific to the target antigen. After incubation, excess conjugate and unbound sample or standard are removed by washing. HRP–streptavidin (SABC) is then added to each well and incubated, followed by the addition of TMB substrate solution. The enzymatic reaction is terminated by adding an acidic stop solution, and the color change is measured at 450 nm using a microplate reader. The concentration of the target antigen in the samples is determined by comparison with the standard curve and is inversely proportional to the OD450 value.

• Precision:
  Intra-assay Precision (Precision within an assay): CV% < 8% ; Intra-assay precision was evaluated by testing multiple replicates of samples within the same plate.; ; Inter-assay Precision (precision between assays): CV% < 10% ; Inter-assay precision was evaluated by testing samples across different plates.

• Calculation of Results:
  1. Average the duplicate readings for each Standard, Control, and Sample, and subtract the mean optical density of the zero Standard. ; 2. Construct a standard curve by plotting the target concentration on the y-axis against absorbance on the x-axis and draw a curve through the data points. ; 3. Determine the sample concentration by substituting the OD450 value into the standard curve. For diluted samples, multiply the calculated value by the corresponding dilution factor.
