Description

QuickStep Human PCT (Procalcitonin) ELISA Kit

The QuickStep Human PCT (Procalcitonin) ELISA Kit is a cutting-edge assay meticulously designed for the precise quantitative measurement of Procalcitonin (PCT) levels in human biological samples.

Procalcitonin, a propeptide of calcitonin, serves as a crucial biomarker associated with various inflammatory conditions and sepsis, making it a valuable indicator of systemic bacterial infections and sepsis severity. This advanced ELISA kit offers high sensitivity and specificity, enabling researchers to obtain accurate and reliable results in detecting PCT levels, providing valuable insights into the body's response to infection and inflammatory processes. Monitoring PCT levels can aid in early diagnosis, risk assessment, and treatment strategies for sepsis, guiding clinicians in making informed decisions to improve patient outcomes. With a focus on delivering exceptional performance and reproducibility, the QuickStep Human PCT (Procalcitonin) ELISA Kit is manufactured under stringent quality control measures. Its user-friendly protocol and robust design make it an excellent choice for researchers and clinicians aiming to explore the role of PCT in infectious diseases and sepsis management. Trust in the accuracy and precision of this ELISA kit to enhance your research in the field of infection biology and sepsis diagnostics.

This ELISA kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Human PCT. Samples (or Standards) and biotinylated detection antibody specific for Human PCT are added to the micro ELISA plate wells. Human PCT would combine with the specific antibody. Then Avidin-Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate well and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Human PCT, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 ± 2 nm. The OD value is proportional to the concentration of Human PCT. You can calculate the concentration of Human PCT in the samples by comparing the OD of the samples to the standard curve.

Procalcitonin (PCT), the precursor of the hormone calcitonin, comprises 116 amino acids and is present in minute quantities under healthy conditions[1]. PCT and other calcitonin precursors in serum are present at less than 50 pg/mL in healthy individuals, but are highly elevated in serum where conditions leading to systemic inflammatory response syndrome or sepsis prevail. The level of PCT has been observed to increase significantly with bacterial infection and correlate to the severity of the infection. Therefore, serum PCT has been considered a powerful biomarker for the diagnosis of bacterial infection[2]. PCT has been proven to have high accuracy as a marker of infection in adult patients, particularly in sepsis. In children it has been investigated in several conditions, including neonatal sepsis, severe infection in neutropenic children, and other specific bacterial infections (e.g. urinary tract infections, pneumonia, bone and joint tissue infections).
