Synonyms:CFTR, ABC35, ABCC7, CF, CFTR/MRP, MRP7, TNR-dJ760C5.1, cystic fibrosis transmembrane conductance regulator

Sensitivity: 0.10 ng/mL
This ELISA kit applies to the in vitro quantitative determination of Human CFTR concentrations in serum, plasma and other biological fluids.
This 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 CFTR. 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 CFTR and Avidin-Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate well and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Human CFTR, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of Human CFTR. You can calculate the concentration of Human CFTR in the samples by comparing the OD of the samples to the standard curve.
|Detection Range||0.16—10 ng/mL|
|Sample Volume Required Per Well||100μL|
|Sample Type||Serum, plasma and other biological fluids|
This kit recognizes Human CFTR in samples. No significant cross-reactivity or interference between Human CFTR and analogues was observed.
As the OD values of the standard curve may vary according to the conditions of the actual assay performance (e.g. operator, pipetting technique, washing technique or temperature effects), the operator should establish a standard curve for each test. Typical standard curve and data is provided below for reference only.
Intra-assay Precision (Precision within an assay): 3 samples with low, mid range and high level Human CFTR were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, mid range and high level Human CFTR were tested on 3 different plates, 20 replicates in each plate.

|C V (%)||6.52||5.79||4.18||6.38||4.13||3.86|
The recovery of Human CFTR spiked at three different levels in samples throughout the range of the assay was evaluated in various matrices.
|Sample Type||Range (%)||Average Recovery (%)|
|EDTA plasma (n=5)||86-96||91|
|Cell culture media (n=5)||95-108||101|
Samples were spiked with high concentrations of Human CFTR and diluted with Reference Standard & Sample Diluent to produce samples with values within the range of the assay.
|Serum (n=5)||EDTA plasma (n=5)||Cell culture media (n=5)|

Asked: Hello, I was wondering if the reference standard is a fragment of the human CFTR or the whole protein? If it is a fragment, what region is it from? Thank you.
adminSubmitted [ Sep 27 2018 ]
Answered: Thanks for your question. The standard is recombinant protein corresponding to C terminal of human CFTR 1235~1480aa.

Asked: Hi, is this kit specific to human CFTR, or would it also detect the mouse one? Thanks a lot, Natalie
adminSubmitted [ Aug 02 2018 ]
Answered: This kit is specific to human CFTR, so it can't detect mouse CFTR.
