FAA Fixative Solution (70% Ethanol)

Product Information

Description

In histopathology, the tissue must be promptly and effectively fixed before subsequent embedding and sectioning can be completed. Organization fixed role is to maintain the inherent morphology and structure of organization, cell, prevent bacteria corrosion and tissue autolysis, save the inherent material inside the cell, the cell protein coagulation, as far as possible to reduce or end of endogenous and exogenous enzyme reaction, keep the cell or tissue basically like living material, also can make the organization hardening, easy to repair the cut of the organization. For certain infectious specimens, can prevent the spread of disease; preserve the gross specimen. Finally, fixation can enhance the effect of staining.

FAA fixing solution (70%) of this product, namely formaldehyde-ethanol-glacial acetic acid fixing solution, is prepared by 5% formalin, 5% glacial acetic acid, and 90% 70% ethanol. It is suitable for the fixation and preservation of general plant roots, stems, leaves, anthers and ovary tissues, and is widely used in the study of plant morphology and anatomy. The best advantage of this fixative is that it can also act as a preservative, but it is not suitable for chromosome observation.

This product is available in 500mL bottles and 15mL single containers to meet various needs. One single installation is ready to use, to avoid pollution.

Storage and Handling Conditions

Transport at room temperature; Store in a cool and dry place, away from direct sunlight, valid for 24 months.

Assay Protocol

After the plant tissue is removed, it is rinsed with water and then placed in FAA fixing solution. Larger tissue needs to be cut into small pieces and fixed again. Generally, it is fixed in FAA fixative for more than 24 h. Small or young tissue can reduce the time appropriately according to the size of the material. If possible, the sample is immersed in the fixation solution and then the fixation can be promoted by vacuuming.

Note

1. Use the product in a well-ventilated environment with proper protection to avoid inhalation.

2. To ensure that the fixation solution fully penetrates the tissue, additional vacuuming treatment can be added.
