The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm  ± 2 nm
Recombinant Human Transforming Growth Factor beta 1 is produced by our Mammalian expression system and the target gene encoding Leu30-Arg278(Cys33Ser) is expressed
The Human NCAD (Neural Cadherin) ELISA kit uses the Sandwich-ELISA principle
The concentration of Human SOD1 in tested samples can be calculated by comparing the OD of the samples to the standard curve
Human Complement Component 5 ELISA Kit PC1 The optical density (OD) isThe Human Complement Component 5 ELISA kit uses the Sandwich ELISA principle. The micro ELISA plate provided in this kit has been pre coated with an antibody specific to Human C5. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Human C5 and Avidin Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate well and
