General description

Neo-Clear (xylene substitute) - for microscopy, is an aliphatic hydrocarbon mixture that can substitute the same applications as xylene in the histo-medical lab - histoprocessing, deparaffination and clearing after dehydration in staining process. It is not necessary to change methods or incubation times when using Neo-Clear instead of xylene. As the evaporation rate of Neo-Clear is lower then xylene, it has less odor and the disturbing smell in the lab is reduced significantly. Neo-Clear is more sensitive against water in solvents (turbidity can occur), thus, it is essential to avoid technical qualities of solvents. It is an IVD registered product and CE certified, thus can be used for clinical diagnostic purposes. For more details, please see instructions for use (IFU). The IFU can be downloaded from this webpage.

Questions

1–4 of 4 Questions  
  1. Are there any experiences with adipose/fat tissue and NeoClear? How long should be the incubation times on 40°C?

    1 answer
    1. The Instructions For Use for NeoClear provides a procedure for use in preparing paraffin embedded sections. Only the paraffin is heated to 60°C. All other steps are performed at room temperature. There is no available information for using NeoClear at 40°C. The Instructions for Use for NeoClear are found on the website's product detail page.
      If using for deparaffinization NeoClear is similar in use to Xylene. The user may however need to slightly extend the times for each NeoClear station.
      The Instructions for Use state that NeoClear is more sensitive to water. This means it may be necessary to change out the various stations of NeoClear on your staining, compared to changing out Xylene on the staining row.

  2. Could this melt the polycarbonate membranes just like in the case of xylene?

    1 answer
    1. The product's chemical composition is "hydrocarbons, C10-C12, Isoalkanes at 100% or less. It is not known whether Neo-Clear is compatible with Polycarbonate.

  3. Is it possible to use NeoClear with paraffin tissue that was initially processed using Xylene?

    1 answer
    1. After embedding the slides in paraffin, Neoclear or Xylene can be used to clear the slides and remove the paraffin before staining. If NeoClear is chosen, NeoMount should serve as the permanent mounting media. It is generally not recommended to use NeoClear and a xylene-based permanent mounting media, as the standard practice in histology is to use a clearing agent that matches the permanent mounting media. If an aqueous mounting media is utilized, the slides are stained, washed in water, and then coverslipped with the aqueous mounting media. In the case of aqueous mounting media, the slides do not undergo NeoClear or Xylene treatment.

  4. Is the solvent Neo Clear 1.09843.5000 compatible with a xylene-based mounting medium, or there is any recommendation of any other mounting medium?

    1 answer
    1. Neo Clear is best used with Neo Mount, while Xylene should be avoided.
