Abcam, ab256641, Human Complement Factor D Antibody Pair - BSA and Azide free

Size: 10 x 96Tests
Human Complement Factor D Antibody Pair - BSA and Azide free is a kit containing recombinant capture and detector antibodies in a carrier-free formulation for the measurement of Human Complement Factor D.
Key facts
Reacts with:Human,
Assay type:ELISA set,
Range:15.63 - 1000 pg/mL,
Assay Platform:Reagents

Product details:
The Antibody Pair can be used to quantify Human Complement Factor D. BSA and Azide free antibody pairs include unconjugated capture and detector antibodies suitable for sandwich ELISAs. The antibodies are provided at an approximate concentration of 1 mg/ml as measured by the protein A280 method. The recommended antibody orientation is based on internal optimization for ELISA-based assays. Antibody orientation is assay dependent and needs to be optimized for each assay type. Both capture and detector antibodies are rabbit monoclonal antibodies delivering consistent, specific, and sensitive results.
For additional information on the performance of the antibody pair, see the equivalent SimpleStep ELISA® Kit (
ab243686
), which uses the same antibodies. However, due to differences in their formulation, this antibody pair cannot be used with the consumables provided with our SimpleStep ELISA Kits. Please note that the range provided for the pairs is only an estimation based on the performance of the related product using the same antibody pair. Performance of the antibody pair will depend on the specific characteristics of your assay. We guarantee the product works in sandwich ELISA, but we do not guarantee the sensitivity or dynamic range of the antibody pair in your assay.

Factor D also known as complement factor D or CFD protein is a serine protease involved in the alternative pathway of the complement system. It plays a mechanical role by cleaving factor B when it is bound to C3b forming the active C3 convertase C3bBb. This enzyme is relatively small with a mass of approximately 28.5 kDa. It is mainly expressed in adipose tissue but it can also be found in the blood plasma.
Biological function summary
Factor D aids the immune system's ability to destroy pathogens. As part of the alternative complement pathway it acts independently and does not associate with larger protein complexes. Its activation of the alternative pathway leads to direct lysis of pathogens therefore contributing to innate immunity.
Pathways
Factor D participates specifically in the complement activation pathway particularly in the innate immune response. It works closely with other proteins in the complement system such as factor B and C3. This pathway enhances the opsonization and removal of microbes and damaged cells acting in parallel with the classical pathway of the complement system.
Abnormal function or regulation of factor D can relate to chronic inflammation and age-related macular degeneration. Disorders involving factor D may involve excess complement activation leading to tissue damage. The role of factor D in these diseases often connects it to other key complement components such as C3 and factor B which can also become problematic when dysregulated.
