semen, vaginal secretions, which
Some time of sample collection, preservation methods and has certain requirements.
Collection (a) clinical specimens
A, blood samples:Some physiological factors, such as smoking, eating, exercise, mood
swings, pregnancy, postural changes in blood can affect certain ingredients, even some
of diurnal variation. Therefore, blood samples
Acquisition should avoid interference physiological factors, consistent with appropriate
conditions, such as can not be avoided, should indicate the factors on the specimen.
1. Peripheral:Usually select the inside of blood left ring finger, the portion should be
no frostbite, inflammation, edema, damage. If the site does not meet the requirements to
other parts of the fingers instead. For burn patients, optional leather
Intact skin at the blood. As part of routine blood tests (eg, white blood cell count,
sort, etc.) affected by physiological factors fluctuation is too large, when compared to
the conditional should be consistent. It relates to the body, blood clotting function
Can test items (such as platelet count, bleeding time or clotting time) testing, we must
pay attention to understand whether the patient used anticoagulant, procoagulant drugs
in order to reduce or avoid interfering factors

2. Blood:In addition to involving a variety of projects such as hemostasis and
thrombosis detector requires the use of anticoagulated blood plasma, the current
analysis to detect the vast majority of projects can be directly detected using blood
serum. In the serum test items
, Some (such as blood sugar, blood fat) diet and circadian factors influenced, fasting
blood samples were generally appropriate; some decay rapidly in the blood (serum enzyme
activity assay such as ACP activity, etc.),
0 ~ 4 ℃ storage is not an activity decreased, the detection of these projects must be
timely and fast; some (such as creatine kinase) influenced by exercise and other
factors. Avoid hemolysis occurs when blood is also important
And, more particularly potassium, LDH and other measurement.
B, urine samples:With the same blood samples, urine samples affect diet, exercise,
medication and other factors that are also large, especially on the diet, so the morning
urine generally superior to random urine. Means getting up early morning urine
After the first urine specimens, representing concentrated and acidified visible
components (such as blood cells, epithelial cells, tubular) easy to observe the relative
concentration. Random urine that is a random urine specimens convenient, but by diet,
Sports, and even more the influence of drugs, prone to false positive and false negative
results, such as diet proteinuria, glucosuria diet, vitamin C interference occult blood

I alternate freezing.
Q:Do
I have to run all of my standards and samples in duplicate?
A:Yes, the duplicates are run in order to monitor assay precision and increase
confidence in the assay results obtained.
Q:Do
I have to run all of my samples at one time?
A:No, each kit uses stripwell microplate. This allows the user to analyse different
numbers of samples at different times.
Q:What
types of reproducible results are obtained with the assays?
A:Each kit comes with a manual containing a graph of typical data obtained. Any
variation in operator, pipetting and washing technique, incubation time or temperature,
and kit age can cause variation in result. Each user should obtain their own standard
curve.
Q:Is
it possible to store the reagents other than indicated?
A:Storage of the kit components under conditions other than indicated is not recommended
in order to assure proper performance of the test.
Q:How
should I store my samples?
A:Samples should be stored at -20oC or lower temperature. For long-term storage, it is
recommended to freeze them at -70oC -80oC.
Q:Can
I modify the protocol?
A:BG ELISA kits have been optimized to provide the best possible results. Modifying the
format or protocol may give inaccurate and wrong results.
Q:Can
I use a sample type that is not recommended in the kit insert?
A:The kit has been validated for the sample types listed in the kit insert. Sample types
other than those validated have not been tested. Contact Technical Service for further
information.
Q:My
samples generated values that were outside the dynamic range of the assay. Can I use
these values?
A:It is recommended that only sample values that fall within the range of the standard
curve be used. Values outside the range of the standard curve are generally non-linear,
which can lead to incorrectly extrapolated values. Samples that generate values higher
than the highest standard should be (further) diluted and the assay repeated. If samples
fall below the range of the assay, the sample is considered to be non-detectable.
Q:Do
I have to run a Blank or Zero Standards every time?
A:Yes, these are required for the calculations, and reflect any subtle but significant
performance changes from day to day and assay to assay. They are also extremely helpful
when troubleshooting the source of a particular assay problem.
Q:Can
I alter the volume of sample I use in the assay?
A:It is not recommended that you alter the volumes since all BG kits are designed for
optimal performance at the given volumes
Q:Can
components from different kits be used?
A:Each kit contains components which have specific lot numbers to ensure that all of the
components are performing optimally alone, as well as with all of the other components
in the kit. QC testing is performed on these specific lots. It is never recommended to
use your own components or components from other kits or vendors.
Q:My
standard curve looked fine, but I didn’t get a signal in my sample when I expected
to, why?
A:The sample may not contain the analyte. A matrix effect may be masking the detection.
Ensure that the recommended dilution was followed as stated in the kit insert. If
dilution was recommended, check to be sure that the dilution was performed properly.
Over-dilution may cause the sample to fall below the range of the standard curve.
Q:How
do you recommend I wash my plate?
A:If you are using an automated plate washer we recommend that the calibration be
checked on a regular basis, and that the system is flushed with the Plate Washing Buffer
prior to washing. The same is true for a manual washer. A repeater or a wash bottle can
also be used. The user should be careful to ensure that all of the contents are
aspirated and the plate tapped dry on lint-free paper.
Q:Do
I need to use a plate shaker?
A:Reliable results can be obtained without a plate shaker, but the O.D.'s will generally
be lower than those obtained using a plate shaker.
Q:Why
do I have to use wavelength correction between 450-570nm?
A:For the ELISA assay, reading at dual wavelengths is done to correct for the optical
density contributed by the plastic well, the lamp and optical fluctuations.
Q:If
I extract my sample, do I still need to follow the recommended dilutions given in
the kit insert?
A:The amount of sample dilution needed after an extraction procedure will be affected by
the effects of purification and concentration in the protocol used. The amount of
dilution or concentration will have to be determined by the end-user.
Q:What
is the expected concentration of analyte that I should expect to find?
A:The amount of a given analyte may vary not only from species-to-species, but also
between tissue and cellular sources. The best source of this information is the current
literature that is easily accessed through the Internet at multiple scientific
databases.
Q:My
optical densities were a little higher (or lower) than those in the manual that came
with my kit. Why?
A:The optical density is affected by a number of physical conditions such as time and
temperature. We suggest that you shorten or lengthen the final incubation with substrate
solution to compensate.
Q:What
are the reasons for High Background?
A:1) Improper Washing: Check volume of washing buffer reservoir and make sure all
recommended washing steps are performed.
2) Contaminated Substrate: Make sure there is no contamination of the substrate with
metal ions or oxidizing reagents, before use. Keep the extra substrate solution
separately during the ELISA substrate development time.
3) Substrate exposed to light: Exposure to light may result in a blue color of the
substrate. Keep solutions in the dark (vial) until ready to dispense into the plate.
4) Wrong Incubation Times/Temperatures: Generally follow the test protocol regarding
incubation times and temperatures. However, if all wells are intensely and equally
colored with no intensity gradient observed in the standard dilution series, then it may
be necessary to observe the substrate reaction as the color is developing, in order to
stop the reaction sooner.
