Analysis of Periostin/OSF-2 (Human) by MSD Hypersensitive Multi-Factor Electrochemiluminescence Analyzer (CAT#: STEM-MB-0491-LGZ)

Introduction

Periostin (POSTN, PN or OSF-2) is an extracellular matrix secreted protein. Human Periostin protein contains 836 amino acids, molecular weight is about 93.3kDa, about 36kbp, located on chromosome 13q13.3. The human Periostin protein structure contains an amino-terminal secretory signal peptide, a cysteine-rich amino-terminus, four homologous repeat regions and a hydrophilic carboxyl-terminus.

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

Neurobiology/Neurodegeneration

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
