The best Human Transferrin ELISA KIT and other products, quick delivery, high quality.
The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Creatine Kinase, Brain (CKB). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Creatine Kinase, Brain (CKB). Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Creatine Kinase, Brain (CKB), biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Creatine Kinase, Brain (CKB) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
A microtiter plate (spelled Microtiter is a registered trade name in the United States) or microplate or micro well plate or multiwell, is a flat plate with multiple "wells" used as small test tubes. The microplate has become a standard tool in analytical research and clinical diagnostic testing laboratories. A very common usage is in the enzyme-linked immunosorbent assay (ELISA), the basis of most modern medical diagnostic testing in humans and animals. A microplate typically has 6, 24, 96, 384 or 1536 sample wells arranged in a 23 rectangular matrix. Some microplates have even been manufactured with 3456 or 9600 wells, and an "array tape" product has been developed that provides a continuous strip of microplates embossed on a flexible plastic tape.
E05 478 566 350 170 or Enzyme-Linked Immunosorbent Assays,E05 478 566 350 170 or Enzyme-Linked Immunosorbent Assays,Human proteins, cDNA and human recombinants are used in human reactive ELISA kits and to produce anti-human mono and polyclonal antibodies. Modern humans (Homo sapiens, primarily ssp. Homo sapiens sapiens). Depending on the epitopes used human ELISA kits can be cross reactive to many other species. Mainly analyzed are human serum, plasma, urine, saliva, human cell culture supernatants and biological samples.
The stability of kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition. To minimize extra influence on the performance, operation procedures and lab conditions, especially room temperature, air humidity, incubator temperature should be strictly controlled. It is also strongly suggested that the whole assay is performed by the same operator from the beginning to the end.
Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Creatine Kinase, Brain (CKB) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Creatine Kinase, Brain (CKB) were tested on 3 different plates, 8 replicates in each plate.

The Stop Solution is acidic. Do not allow to contact skin or eyes. Calibrators, controls and specimen samples should be assayed in duplicate. Once the procedure has been started, all steps should be completed without interruption.
-20°C. Bring all reagents to room temperature before beginning test. The kit may be stored at 4°C for immediate use within two days upon arrival. Reseal any unused strips with desiccant pack. Minimize freeze/thaw cycles.
This assay has high sensitivity and excellent specificity for detection of Creatine Kinase, Brain (CKB). No significant cross-reactivity or interference between Creatine Kinase, Brain (CKB) and analogues was observed.
This assay doesn't seem to cross-react with other species. For more information about cross-reactivity please contact us.
