DatasheetSpecific ReferencesReviewsRelated ProductsProtocols
Materials provided
Capture Ab:0.4 mg/mL of mouse anti-COQ7 monoclonal antibody. Dilute to a working concentration of 1.0 μg/mL in CBS before coating.
Detection Ab:0.5 mg/mL rabbit anti-COQ7 polyclonal antibody conjugated to horseradish-peroxidase (HRP). Dilute to working concentration of 0.25 μg/mL in detection antibody dilution buffer before use.
Standard:Each vial contains 100 ng of recombinant COQ7. Reconstitute standard powder with 1 mL detection antibody dilution buffer. After reconstitution, store at -20℃ to -80℃ in a manual defrost freezer. A seven-point standard curve using 2-fold serial dilutions in sample dilution buffer, and a high standard of 2500 pg/mL is recommended.
Sensitivity
The minimum detectable dose of Human COQ7 was determined to be approximately 39.1 pg/ml. This is defined as at least three times standard deviations above the mean optical density of 10 replicates of the zero standard.
Principle of the product
The Human COQ7 ELISA Pair Set is for the quantitative determination of Human COQ7.
This ELISA Pair Set contains the basic components required for the development of sandwich ELISAs.
The Sino Biological ELISA Pair Set is a solid phase sandwich ELISA (Enzyme-Linked Immunosorbent Assay). It utilizes a monoclonal antibody specific for Human COQ7 coated on a 96-well plate. Standards and samples are added to the wells, and any Human COQ7 present binds to the immobilized antibody. The wells are washed and a horseradish peroxidase conjugated rabbit anti-Human COQ7 polyclonal antibody is then added, producing an antibody-antigen-antibody “sandwich”. The wells are again washed and TMB substrate solution is loaded, which produces color in proportion to the amount of Human COQ7 present in the sample. To end the enzyme reaction, the stop solution is added and absorbances of the microwell are read at 450 nm.
Storage
Capture Antibody: Aliquot and store at -20℃ to -80℃ for up to 6 months from date of receipt. Avoid repeated freeze-thaw cycles.
Detection Antibody: Protect it from prolonged exposure to light. Aliquot and store at -20℃ to -80℃ and for up to 6 months from date of receipt. Avoid repeated freeze-thaw cycles.
Standard: Store lyophilized Standard at -20℃ to -80℃ for up to 6 months from date of receipt. Aliquot and store the reconstituted Standard at -80℃ for up to 1 month. Avoid repeated freeze-thaw cycles.
Background

Ubiquinone biosynthesis protein COQ7 homolog, also known as Coenzyme Q biosynthesis protein 7 homolog, Timing protein clk-1 homolog and COQ7, is a mitochondrion inner membrane and peripheral membrane protein which belongs to the COQ7 family. It is expressed dominantly in heart and skeletal muscle. COQ7 is synthesized as a preprotein that is imported into the mitochondrial matrix, where the sequence is cleaved off and the mature protein becomes loosely associated with the inner membrane. This enzyme is responsible for the hydroxylation of 5-demethoxyubiquinone to 5-hydroxyubiquinone. Human COQ7 protein is mostly helical, and contains an alpha-helical membrane insertion. It has a potential N-glycosylation site, a phosphorylation site for protein kinase C and another for casein kinase II, and three N-myristoylation sites. COQ7 is involved in lifespan determination in ubiquinone-independent manner. It is also involved in ubiquinone biosynthesis. COQ7 is potential central metabolic regulator.
