Newcomer Supply Michel Transport Medium and pre-filled Michel Transport Medium Vials, provide a stable medium for transport of fresh unfixed tissues, such as renal, rectal, lymph node, skin and oral mucosa biopsies, which will undergo subsequent frozen sectioning and immunofluorescence studies.
- Michel Transport Medium is not a fixative and does not have any fixative properties.
- Michel Transport Medium is not suitable for transporting cells for flow cytometry or tissues used for fluorescent in-situ hybridization (FISH) studies.
Newcomer Supply Michel Wash Solution is used to rinse Michel Transport Medium from tissue after transport or storage and prior to freezing.
Fixation: Fresh unfixed tissue
Solutions: All solutions are manufactured by Newcomer Supply, Inc.
- Place fresh tissue in an adequate amount of Michel Transport Medium as soon as possible after excision.
- See Procedure Note #1.
- Ensure that the specimen is completely covered with Michel Transport Medium and is free floating.
- Transport tissue to processing site in Michel Transport Medium up to a maximum of five days.
- During transport or storage, maintain cool to ambient temperatures of 4°C to 22°C.
- Upon receipt, wash tissue held in Michel Transport Medium with Michel Wash Solution; three changes, 10 minutes each.
- Freeze tissue sample(s) per laboratory protocol.
- Tissue placed in Michel Transport Medium may provide adequate results when processed for light microscopy review.
- Wash tissue 2-3 minutes in tap water and place in appropriate fixative prior to processing.
- See Procedure Note #2.
- Previously frozen tissue will not provide optimal testing results and should not be used with Michel Transport Medium.
- Tissues held/transported in Michel Transport Medium, may provide satisfactory histological results if conditions as outlined in Procedure Steps #3 and #4 are maintained. Morphology detail will not be equal to that of expediently fixed and processed tissue.
