The modulator divides the input light into two equal signals and enters the two optical branches of the modulator respectively. The materials used in the two optical branches are electro- optical materials, and their refractive index varies with the external applied electric signal. Because the change of the refractive index of the optical branch will lead to the change of the signal phase, when the output ends of the two branch signal modulators are combined together again, the synthesized optical signal will be an interference signal with varying intensity, which is equivalent to converting the change of electric signal into the variation of optical signal and realizing the modulation of light intensity. As a reliable optical transceiver manufacturer and optical transceiver supplier, we will provide more kinds of related products for sale, anything you need, please contact us.

E02A0015 Rat Active Caspase 3 ELISA kit Rat caspase 3 elisa kit is suitable for the detection of samples from Rat species. Active caspase 3 can also be called CPP32, CPP32B, SCA1, Apoptain, Yama, Apoptosis-Related Cysteine Peptidase, Cysteinyl Aspartate Specific Proteinases 3, SREBP cleavage activity 1, Active casp3, casp3, casp-3, casp 3. Principle of the Assay ACTIVE CASPASE 3 ELISA kit applies the quantitative sandwich enzyme immunoassay technique. The microtiter plate has been pre-coated with a monoclonal antibody specific for ACTIVE CASPASE 3. Standards or samples are then added to the microtiter plate wells and ACTIVE CASPASE 3 if present, will bind to the antibody pre-coated wells. In order to quantitatively determine the amount of ACTIVE CASPASE 3 present in the sample, a standardized preparation of horseradish peroxidase (HRP)-conjugated polyclonal antibody, specific for ACTIVE CASPASE 3 are added to each well to “sandwich” the ACTIVE CASPASE 3 immobilized on the plate. The microtiter plate undergoes incubation, and then the wells are thoroughly washed to remove all unbound components. Next, substrate solutions are added to each well. The enzyme (HRP) and substrate are allowed to react over a short incubation period. Only those wells that contain ACTIVE CASPASE 3 and enzyme-conjugated antibody will exhibit a change in color. The enzyme-substrate reaction is terminated by addition of a sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450 nm. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The ACTIVE CASPASE 3 concentration in each sample is interpolated from this standard curve. Citations of Rat Active caspase 3 ELISA kit E02A0015 has been referenced in the below publications: Hypoxic Preconditioning Augments the Therapeutic Efficacy of Bone Marrow Stromal Cells in a Rat Ischemic Stroke Model. Shanghai Bluegene Biotech has been committed to R&D of ELISA kits, making our ELISA kits more convenient for researchers to use on the premise of guaranteeing the quality, thus assisting scientific research for our customers. So far, we have received 1200 published papers from researchers with a total of about 500 kinds of ELISA Kits that have been cited.
