  • Product overview

    Complement C6 in vitro SimpleStep ELISA® (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of Complement C6 protein in Human serum, plasma, saliva, and cell supernatant samples.

    The SimpleStep ELISA® employs an affinity tag labeled capture antibody and a reporter conjugated detector antibody which immunocapture the sample analyte in solution. This entire complex (capture antibody/analyte/detector antibody) is in turn immobilized via immunoaffinity of an anti-tag antibody coating the well. To perform the assay, samples or standards are added to the wells, followed by the antibody mix. After incubation, the wells are washed to remove unbound material. TMB substrate is added and during incubation is catalyzed by HRP, generating blue coloration. This reaction is then stopped by addition of Stop Solution completing any color change from blue to yellow. Signal is generated proportionally to the amount of bound analyte and the intensity is measured at 450 nm. Optionally, instead of the endpoint reading, development of TMB can be recorded kinetically at 600 nm.

    Complement C6 is involved in the innate and adaptive immune response via its role in the membrane attack complex (MAC). Along with C5b, C7, C9 and C9, these proteins form the MAC, which creates pores in the plasma membrane of foreign cells.

  • Research areas

  • Function

    Constituent of the membrane attack complex (MAC) that plays a key role in the innate and adaptive immune response by forming pores in the plasma membrane of target cells.
  • Involvement in disease

    Defects in C6 are the cause of complement component 6 deficiency (C6D) [MIM:612446]. A rare defect of the complement classical pathway associated with susceptibility to severe recurrent infections, predominantly by Neisseria gonorrhoeae or Neisseria meningitidis.
  • Sequence similarities

    Belongs to the complement C6/C7/C8/C9 family.
    Contains 1 EGF-like domain.
    Contains 2 Kazal-like domains.
    Contains 1 LDL-receptor class A domain.
    Contains 1 MACPF domain.
    Contains 2 Sushi (CCP/SCR) domains.
    Contains 3 TSP type-1 domains.
  • Post-translational

    All cysteine residues are assumed to be cross-linked to one another. Individual modules containing an even number of conserved cysteine residues are supposed to have disulfide linkages only within the same module.

Our Abpromise guarantee covers the use of ab230934 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
Sandwich ELISA Use at an assay dependent concentration.


  • SimpleStep ELISA technology allows the formation of the antibody-antigen complex in one single step, reducing assay time to 90 minutes. Add samples or standards and antibody mix to wells all at once, incubate, wash, and add your final substrate. See protocol for a detailed step-by-step guide.


  • The Complement C6 standard curve was prepared as described in Section 10.

  • The concentrations of Complement C6 were measured in duplicates, interpolated from the Complement C6 standard curves and corrected for sample dilution. Undiluted samples are as follows: serum 1:2000, plasma (citrate) 1:2000, plasma (EDTA) 1:2000, plasma (heparin) 1:2000, and saliva 1:2. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean Complement C6 concentration, corrected for dilution, was determined to be 21 µg/mL in serum, 19 µg/mL in plasma (citrate), 16 µg/mL in plasma (EDTA), 15 µg/mL in plasma (heparin), and 4 ng/mL (0.004 µg/mL) in saliva.

  • Interpolated, dilution factor-corrected values are plotted (mean +/- SD, n=2). The mean Complement C6 concentration was determined to be 23 µg/mL with a range of 16 – 29 µg/mL.
