Procedure Overview

The method is based on a competitive colorimetric ELISA assay. The Kanamycin-BSA has been coated in the plate wells. During the analysis, sample and Kanamycin antibody (Antibody #1) and HRP-Conjugate (HRP-Conjugated Antibody #2) are added to the wells for incubation. If the Kanamycin residue is present in the sample, it will compete with the Kanamycin on the plate wells for the Kanamycin antibody, The secondary antibody, tagged with a peroxidase enzyme, targets the primary antibody that is complexed to the drug coated on the plate wells. The resulting color intensity, after addition of the HRP substrate (TMB), has an inverse relationship with the Kanamycin residue concentration in the sample.


Kit Contents, Storage and Shelf Life

REAGEN Kanamycin ELISA Test Kit has the capacity for 96 determinations or testing of 42 samples in duplicate (assuming 12 wells for standards). Return any unused microwells to the foil bag and reseal them with the desiccant provided in the original package. Store the kit at 2-8°C *.

Required Materials Not Provided With the Kit​

  • Microtiter plate reader (450 nm)

  • Tissue Mixer (e.g. Omni Tissue Master Homogenizer)

  • Vortex mixer (e.g. Genie Vortex mixer from VWR)

  • 10, 20, 100 and 1000 uL pipettes

  • Multi-channel pipette: 50-300 uL (Optional)


Warnings and Precautions

  • The standards contain Kanamycin. Handle with particular care.
  • Do not use the kit past the expiration date.
  • Do not intermix reagents from different kits or lots except for components with the same part No’s within their expiration dates. ANTIBODIES AND PLATES ARE KIT-AND LOT-SPECIFIC.
  • Try to maintain a laboratory temperature of 20°–25°C (68°–77°F). Avoid running assays under or near air vents, as this may cause excessive cooling, heating and/or evaporation. Also, do not run assays in direct sunlight, as this may cause excessive heat and evaporation. Cold bench tops should be avoided by placing several layers of paper towel or some other insulation material under the assay plates during incubation.
  • Make sure you are using only distilled or deionized water since water quality is very important.
  • When pipetting samples or reagents into an empty microtiter plate, place the pipette tips in the lower corner of the well, making contact with the plastic.
  • Incubations of assay plates should be timed as precisely as possible. Be consistent when adding standards to the assay plate. Add your standards first and then your samples.
  • Add standards to plate only in the order from low concentration to high concentration as this will minimize the risk of compromising the standard curve.
  • Always refrigerate plates in sealed bags with a desiccant to maintain stability. Prevent condensation from forming on plates by allowing them equilibrate to room temperature (20 – 25°C / 68 – 77°F) while in the packaging.

Be sure samples are properly stored. In general, samples should be refrigerated at 2-4°C for no more than 1-2 days. Freeze samples to a minimum of -20°C if they need to be stored for a longer period. Frozen samples can be thawed at room temps (20 – 25°C / 68 – 77°F) or in a refrigerator before use.

  • Preparation of 1×Sample diluent:Mix 1 volume of 10×Sample diluent with 9 volumes of distilled water.

Reagent Preparation

IMPORTANT: All reagents should be brought up to room temperature before use (1 – 2 hours at 20 – 25°C / 68 – 77°F); Make sure you read “Warnings and Precautions” section on page 3. Solutions should be prepared just prior to ELISA test. All reagents should be mixed by gently inverting or swirling prior to use. Prepare volumes that are needed for the number of wells being run. Do not return the reagents to the original stock tubes/bottles. Using disposable reservoirs when handling reagents can minimize the risk of contamination and is recommended.

  • Preparation of 1X Wash Solution

Mix 1 volume of the 20X Wash Solution with 19 volumes of distilled water.


ELISA Testing Protocol

Label the individual strips that will be used and aliquot reagents as the following example:


Component Volume per Reaction 24 Reactions
Kanamycin Antibody #1 50uL 1.2mL
HRP-Conjugated Ab #2 50uL 1.2mL
1X Wash Solution 1.0 mL 24mL
Stop Buffer 100 uL 2.4 mL
TMB Substrate 100 uL 2.4 mL
  • Add 50 uL of each Kanamycin Standards in duplicate into different wells (Add standards to plate only in the order from low concentration to high concentration).

  • Add 50 uL of each sample in duplicate into different sample wells.

  • Add 50 uL of HRP-Conjugated Ab#2 to each well and 50 uL of Kanamycin Antibody #1 to each well. Mix well by gently rocking the plate manually for 30s.

  • Incubate the plate for 30 minutes at room temperature (20 – 25°C / 68 – 77°F). (Avoid direct sunlight and cold bench tops during the incubation. Covering the microtiter plate while incubating is recommended).

  • Wash the plate 4 times with 250 uL of 1X Wash Solution. After the last wash, invert the plate and gently tap the plate dry on paper towels (Perform the next step immediately after plate washings. Do not allow the plate to air dry between working steps).

  • Add 100 uL of TMB substrate. Time the reaction immediately after adding the substrate. Mix the solution by gently rocking the plate manually for 30s while incubating(Do not put any substrate back to the original container to avoid any potential contamination. Any substrate solution exhibiting coloration is indicative of deterioration and should be discarded. Covering the microtiter plate while incubating is recommended).

  • After incubating for 15 minutes at room temperature (20 – 25°C / 68 – 77°F), add 100 uL of Stop Buffer to stop the enzyme reaction.

  • Read the plate as soon as possible following the addition of Stop Buffer on a plate reader with 450 nm wavelength (Before reading, use a lint-free wipe on the bottom of the plate to ensure no moisture or fingerprints interfere with the readings).


Kanamycin Concentration Calculations

A standard curve can be constructed by plotting the mean relative absorbance (%) obtained from each reference standard against its concentration in ng/mL on a logarithmic curve.

Relative absorbance (%) = absorbance zero standard or sample x 100

Use the mean relative absorbance values for each sample to determine the corresponding concentration of the tested drug in ng/mL from the standard curve.

The following figure is a typical chloramphenicol standard curve.
