8. Rapid Mycotoxin Test / "ELISA Test"
Antibody coated column is used to trap the mycotoxin. This trapped toxin is then eluted using approximate solvent and quantified in fluorometer.
Equipments :
- Immuno affinity column
- Affinity column stand with syringe
- Cuvette
- Calibrated Fluorometer
- Blender
- Fluted filter paper
Reagent:
- Test developer
- Methonol : water (80 : 20 by volume)
- Mycotoxin wash buffer
Procedure:
- 50 gms of sample + 5 gms of NaCl + 100 ml of methanol water (80 : 20) Note : NaCl is not added in case of Ochra Test
- Blend at high speed and filter
- Pipette filtered extract into clean vessel Aflatoxin, Ochratoxin : 10 ml
- Zearalenone : 1 ml
- Dilute with purified water and mix Aflatoxin, Ochratoxin : 40 ml Zearalenone : 49 ml
- Filter
- Remove top cap and attach the syringe (cut 1/8 inch bottom of column )
- Pass filtered diluted extract at the rate of 1-2 drops/second Aflatoxin : 2 ml Ochratoxin, Zearalenone : 10ml
- Pass water at the rate of 1-2 drops/second Aflatoxin, Zearalenone : 5 ml Ochratoxin : First 10 ml Mycotoxin wash buffer, Later 10 ml distilled water Courtesy : VICAM
- Elute toxin in glass cuvette Aflatoxin, Zearalenone : Pass 1 ml HPLC grade methanol Ochratoxin : Pass 1.5 ml Ochratoxin eluting soln.
- Add 1 ml of developer to the cuvette and mix well
- Read in calibrated fluorometer
