Sulfonamides residues (SAs) rapid test strip (milk)
Catalog No. LSY-20040
1. Specifications: 8 dipsticks/bottle, 12 bottles/box
2. Brief
This product is used for testing Sulfonamides residue in milk sample(pure milk and fresh milk) and goat’s milk qualitatively, the whole test procedure only need 6min, easy to operate with high sensitivity.
3. Detection limit in milk [ppb(ug/kg)]
Name | Detection limit | Name | Detection limit |
Sulfadiazine (SD or SDZ) | 1-3 | Sulfafurazole(SIZ) | 30-40 |
Sulfamerazine (SM1) | 1-3 | Sulfamethoxypyridazine (SMPZ) | 20-25 |
Sulfamonomethoxine (SMM) | 1-3 | Sulfachloropyridazine (SCPA) | 10-15 |

Sulfathiazole(ST) | 5-6 | Sulfadimoxine (SDM2) | 20-30 |
Sulfamethoxypyridazine (SMP) | 6-10 | Sulfacetamide | 50-60 |
Sulfaquinoxaline(SQX) | 20-25 | Sulfapyrazole | 50-60 |
Sulfamethoxazole (SMZ) | 10-15 | Sulfadimethoxine | 5-10 |
Sulfamethazine(SM2) | 5-8 | Sulfapyridine(SPD) | 20-40 |
Sulfamethoxydiazine(SMD) | 1-3 | Sulfaphenazolum(SPP) | 20-40 |
4. Principle
The Sulfonamides rapid test dipstick is based on competitive inhibition immuno-chromatographic principle. In the flow process, Sulfonamides in the sample combined with Sulfonamides specific colloidal gold-labeled monoclonal antibody, Inhibit the combination between antibody and Sulfonamides -BSA conjugate on Test line of NC membrane, lead to the color change of Test line.
When the sample has no Sulfonamides residue or concentration lower than detection limit, T line is darker than C line. when the concentration is equal to or higher than detection limit, T line is lighter than C line obviously or T line is invisible or T line has same color with C line. No matter whether there is Sulfonamides residue in sample, C line will appear, it means the test is valid.
5. Storage and expiry date
Storage: Store at 2-8 ℃ in dark, sealed, dry place, no frozen.
Expiry date: 12 months; date of production is on box.
