For the quantitative in vitro determination of INHB concentrations in Human culture supernates, serum, plasma and tissue.
INTENDED USE
An enzyme immunoassay quantitative measurement in cell culture in vitro Human INHB supernates, serum, plasma and tissue.
PRINCIPLE
The kit assay Human INHB level in the sample，use Purified Human INHB antibody to coat microtiter plate wells, make solid-phase antibody, then add INHB to wells, Combined INHB antibody which With HRP labeled , become antibody - antigen - enzyme- antibody complex, after washing Compley, Add TMB substrate solution,TMB substrate becomes blue color At HRP enzyme-catalyzed, reaction is terminated by the addition of a sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450 nm. The concentration of INHB in the samples is then determined by comparing the O.D. of the samples to the standard curve.
WARNINGS AND PRECAUTIONS
l This kit is only for scientific research, and shall not be used as a clinical diagnosis of use.
l Before starting the assay, read the instructions compley and carefully. Use the valid version of the package insert provided with the kit. Be sure that everything is understood.
l The microplate contains snap-off strips. Unused wells must be stored at 2 °C to 8 °C in the sealed foil pouch and used in the frame provided.
l Pipetting of samples and reagents must be done as quickly as possible and in the same sequence for each step.
l Use reservoirs only for single reagents. This especially applies to the substrate reservoirs. Using a reservoir for dispensing a substrate solution that had previously been used for the conjugate solution may turn solution colored. Do not pour reagents back into vials as reagent contamination may occur.
l Mix the contents of the microplate wells thoroughly to ensure good test results. Do not reuse microwells.
l Do not let wells dry during assay; add reagents immediay after completing the rinsing steps.
l Allow the reagents to reach room temperature （21-26°C） before starting the test. Temperature will affect the absorbance readings of the assay. However, values for the patient samples will not be affected.
l Never pipet by mouth and avoid contact of reagents and specimens with skin and mucous membranes.
l Do not smoke, eat, drink or apply cosmetics in areas where specimens or kit reagents are handled.
l Wear disposable latex gloves when handling specimens and reagents. Microbial contamination of reagents or specimens may give false results.
l Handling should be done in accordance with the procedures defined by an appropriate national biohazard safety guideline or regulation.
l Do not use reagents beyond expiry date as shown on the kit labels.
l All indicated volumes have to be performed according to the protocol. Optimal test results are only obtained when using calibrated pipettes and microtiterplate readers.
l Do not mix or use components from kits with different lot numbers. It is advised not to exchange wells of different plates even of the same lot. The kits may have been shipped or stored under different conditions and the binding characteristics of the plates may result slightly different.
l Avoid contact with Stop Solution containing 0.5 M H2SO4. It may cause skin irritation and burns.
l Some reagents contain Proclin, BND and/or MIT as preservatives. In case of contact with eyes or skin, flush immediay with water.
l TMB substrate has an irritant effect on skin and mucosa. In case of possible contact, wash eyes with an abundant volume of water and skin with soap and abundant water.
l Chemicals and prepared or used reagents have to be treated as hazardous waste according to the national biohazard safety guideline or regulation.
l For information on hazardous substances included in the kit please refer to Material Safety Data Sheets

ASSAY PROCEDURE
u General Remarks
l All reagents and specimens must be allowed to come to room temperature before use. All reagents must be mixed without foaming.
l Once the test has been started, all steps should be completed without interruption.
l Use new disposal plastic pipette tips for each standard, control or sample in order to avoid cross contamination.
l Absorbance is a function of the incubation time and temperature. Before starting the assay, it is recommended that all reagents are ready, caps removed, all needed wells secured in holder, etc. This will ensure equal elapsed time for each pipetting step without interruption.
l As a general rule the enzymatic reaction is linearly proportional to time and temperature.
l Determine absorption with an ELISA reader at 450 nm against 630 nm as reference. If no reference wavelength is available, read only at 450nm. If the extinction of the highest standard exceeds the measurement range of the photometer, absorption must be measured immediay at 450 nm against 630 nm as reference.

CALCULATION OF RESULTS
l Calculate the average absorbance values for each set of standards, controls and patient samples.
l Construct a standard curve by plotting the mean absorbance obtained from each standard against its.
l Concentration with absorbance value on the vertical（Y） axis and concentration on the horizontal （X） axis.
l Using the mean absorbance value for each sample determine the corresponding concentration from the standard curve.
l Automated method: The results in the IFU have been calculated automatically using a 4 PL.
l （4 Parameter Logistics） curve fit. 4 Parameter Logistics is the preferred calculation method. Other data.
l Reduction functions may give slightly different results.
l The concentration of the samples can be read directly from this standard curve. Samples with.
l Concentrations higher than that of the highest standard have to be further diluted. For the calculation of.
l The concentrations this dilution factor has to be taken into account.
