Analysis of Cytokeratin-19 (Human) by MSD Hypersensitive Multi-Factor Electrochemiluminescence Analyzer (CAT#: STEM-MB-0128-LGZ)

Introduction

Cytokeratin 19 fragment (Cyfra 21-1) is a lung cancer-related tumor marker, belonging to the intermediate filament protein family, with a molecular weight of about 40kD, mainly present in the cytoplasm of tumor cells derived from epithelial cells such as esophageal cancer and lung cancer.




Principle

MSD electrochemiluminescence technology is mainly based on ultra-sensitive multi-factor electrochemiluminescence analyzer MES0 Sector600 or Quickplex SQ120. Through dot matrix technology, the detection of 10 indicators per well can be realized in the 96-hole graphite electrode plate. It can also be customized to realize the screening detection of 100 index wells in a 24-well plate.

Applications

Cancer

Procedure

1. Coat the capture antibody on the well plate.
2. Add samples/calibrators.
3. Add detection antibody.
4. Read the plate and analyze the data.

Materials

• Sample Type: Plasma, Serum
