测定

• 产品概述

  The Human Complement Factor P (CFP) ELISA (Enzyme-Linked Immunosorbent Assay) Kit (ab222864) is designed for detection of Complement Factor P in human plasma, serum, urine, saliva, CSF, and cell culture samples.

  
  

  This assay employs a quantitative sandwich enzyme immunoassay technique that measures human Complement Factor P in approximately 4 hours. A polyclonal antibody specific for human Complement Factor P has been pre-coated onto a 96-well microplate with removable strips. Complement Factor P in standards and samples is sandwiched by the immobilized antibody and a biotinylated polyclonal antibody specific for human Complement Factor P, which is recognized by a streptavidin-peroxidase (SP) conjugate. All unbound material is washed away and a peroxidase enzyme substrate is added. The color development is stopped and the intensity of the color is measured.

  
  

  The entire kit may be stored at -20°C for long term storage before reconstitution - Avoid repeated freeze-thaw cycles.

遗传学

• 说明

  Complement factor P (CFP), also known as properdin, is a plasma glycoprotein that positively regulates the alternative complement pathway convertases (C3bBb) of the innate immune system. CFP consists of 442-amino acids with a molecular weight of 53 kDa and is composed of multiple identical protein subunits. The subunits bind to each other in a head to tail manner to form cyclic dimers, trimers, tetramers, pentamers, and higher cyclic oligomers. It is mainly produced by neutrophils but also by monocytes, T cells, and bone marrow progenitor cells. CFP binds to many microbial surfaces and apoptotic cells. Complement factor P also stabilizes the C3- and C5-convertase enzyme complexes in a feedback loop that ultimately leads to formation of the membrane attack complex and lysis of the target cell.
