can be visualized by staining with good differentiation, it is recommended to use a control preparation.

ISOSLIDE® control preparations are a group of products created to help optimize and standardize the staining

result by enabling a direct comparison of typical control material with laboratory-internal specimens.

The ISOSLIDE® control slides consist of microscope slides with a paraffin section containing the typical

structures of the test method to be used.

The control slide is prepared using sections of suitable animal material. Each pack of ISOSLIDE® control

slides contains 25 slides. One slide is stained with the reference method and is used for comparison. The

24 unstained slides are stained according to the corresponding Merck specification or else can be stained

according to the laboratory-internal specification.

The unstained control slides are stained and subsequently compared with the laboratory material and the

stained control section regarding the staining result.

tissue in routine histological procedures. The material to be decalcified is placed in an excess of

decalcifying solution and demineralized (decalcified) in this. The decalcification time is dependent on

the size and structural density of the hard tissue, while the composition of the decalcifying solution

also exerts a decisive influence on the process. Decalcification of bone and hard tissue requires the use

of either inorganic acids, as is the case with OSTEOMOLL®, which liberates the acids of the mineral

salts and can subsequently be rinsed out.

The decalcifying solution has been stained to facilitate the identification of the decalcifying procedure

– OSTEOMOLL® is blue. The dye used is inert in terms of any effect on the tissue to be decalcified.

When decalcifying sensitive, calcium-containing tissue a solution such as OSTEOSOFT® is used, which

contains complex- or chelate-forming agents that bind the calcium ions of the tissue. This type of

decalcifying solution preserves the antigen structures in the tissue, with the result that immunological

procedures can be conducted. The decalcifying solution has been stained to facilitate the identification

of the decalcifying procedure – OSTEOSOFT® is yellow. The dye used is inert in terms of any effect on

the tissue to be decalcified.
