Reactivity
Rat
Specificity
This assay has high sensitivity and excellent specificity for detection of rat BF. No significant cross-reactivity or interference between rat BF and analogues was observed.
Sequence Length
621
Samples
Serum, plasma, tissue homogenates
Assay Type
Sandwich
Detection Range
1.56 ng/ml -100 ng/ml.
Sensitivity
The minimum detectable dose of rat BF is typically less than 0.39 ng/ml. The sensitivity of this assay, or Lower Limit of Detection (LLD) was defined as the lowest protein concentration that could be differentiated from zero. It was determined the mean O.D value of 20 replicates of the zero standard added by their three standard deviations.
Intra-assay Precision
Intra-assay Precision (Precision within an assay): CV%<8%. Three samples of known concentration were tested twenty times on one plate to assess.
Inter-assay Precision
Inter-assay Precision (Precision between assays): CV%<10%. Three samples of known concentration were tested in twenty assays to assess.
Preparation and Storage
Unopened test kits should be stored at 2 to 8 degree C upon receipt. Please refer to pdf manual for further storage instructions.

Principle of the assay: This assay employs the quantitative sandwich enzyme immunoassay technique. Antibody specific for BF has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any BF present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for BF is added to the wells. After washing, avidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of BF bound in the initial step. The color development is stopped and the intensity of the color is measured.
