Streptomycin (StrepQ) Rapid Test Strip Milk drug residue Improve Product Safety Quality
【Product Name】
Streptomycin (StrepQ) Rapid Test Strip
【Specification】 96T/kit
【Storage Conditions】
Store at 2-8℃ in dry environment.
Expiry date: 12 months
【Intended Application】
The test strip is used for detecting Streptomycin family in raw
commingled cow milk above or below tolerance and/or safe levels.
【Principle】
The kit is a competitive colloidal gold immunoassay method. Sample
is added to sample hole, if there is Streptomycin (StrepQ) in samples,
it will combine with marked antibodies, preventing the marked
antibodies from combining the Streptomycin (StrepQ) antigens of NC
nitrocellulose membrane.
【Technique Data】
Kit sensitivity: 200 ppb (ng/ml) (Final detection limit)
【Kit Contents

96 well tray and sample well with reagent.
Instruction …………………………..1
【Milk Sample Preparation】
1. Collect milk sample from butch, or farm
2. Make sure the milk has no clot.
3. Milk at room temperature, don’t heat or freeze.
4. Thoroughly mix with the reagent before testing.
【Test Procedure】
1. Read the manual instruction before testing. Be sure the raw
commingled milk and test kit is at room temperature.
2. Take one Tube from the box, open tube and take out decided
number of test to be perform, Use the test kit within an hour
beyond time may cause failure of the test. The unused test strip
must be sealed and keep out from sunlight and prevent
moisture.
3. Take the milk sample, drop 200ul (about 4-5drops) into the
sample-well, and thoroughly dissolve the milk with reagents for
5 minutes till the milk presents pink color.
4. Insert the test strip into the sample-well, read the results
after 5 minutes.
【Results Judgment】
Negative(-): control line(C) display red, test line(T) color is
deeper than the control line or the same as the C line, the
result shows that (StrepQ) concentration is less than detection
Limits or not containing (StrepQ).
Positive(+): control line(C) display red, test line(T) color is
shallower than the control line or no color, the result shows
that (StrepQ) concentration is higher than detection Limits.
Invalid: control line (C) doesn’t display, it means the
