Ractopamine (Rac) is one kind of beta-agonist, normally, dissolves
in hydrochloride as Ractopamine hydrochloride called Paylean. Rac
is used as feed additives for transfering adipose tissue to muscle
tissues in pig. Because lots of countries (ex. EU) regard it as
growth hormone, import of Ractopamine remaining meat is banned.
Consequently, a convenient rapid Ractopamine diagnostic kit is
developed and fit in need.
The Ractopamine chromatographic diagnostic kit is based on the
specific immuno-chemical reactions between antigen and antibody. It
relies on the competition between Ractopamine residues in the
sample and? the Ractopamine immobilized on T line on the membrane
for the Ractopamine antibody-dye conjugate. If the drug is
presenting in the sample, it will compete with the drug immobilized
on T line, to the limited amount of dye-antibody. When a sufficient
amount of drug in the sample is presenting, the drug will saturate
the antibody. Thus it will show an extremely light or even
invisible T line, indicating a positive result. If there is a
negative sample (or the amount of the drug is lower than the
minimum detectable concentration 5ppb), it will generate two
obvious lines in both the T and C line section.
3. Contents (50pieces / kit)
1 Test cassette
1 Open the package upon request to avoid the test cassette being
2 Use one cassette and one dropper for one test. Store the rest of
the test cassette in dark at 4-30 ℃ environment and avoid being
3 Avoid touching the membrane in the cassette.
4 Each package containing one test cassette and one drop is for one
time use only. Please do not reuse.
5. Operation procedures
1 Open the aluminum package. Then take out the test cassette.
2 Use the provided dropper to obtain the sample. Drop 3 drops
(about 80 μL) in the sample collect region.
Note:do not drop the sample directly in the test result region. It will
affect the result.
3 Read the results in 5-30 min.
Note:do not wait over than 30 minutes to read the result. Time will
affect the result.
6. Test Result Interpretation
1 Negative (Rac < 5 ppb): T line is even or darker then the C
2 Positive (Rac > 5 ppb): T line is invisible and only C line is
3 Invalid test: If C line does not show which means the test
cassette is out of efficacy, out of date or improper operation.
Please run the test again using another package. If the invalid
tests keep happening, please contact the local distributor.
