Tissue preparation & immunogold labeling with 1 primary antibody on free-floating sections (NDT401c-a):
This service includes tissue preparation, sectioning, immunolabeling, mounting, coverslipping and labeling the slides. As a result, you will receive up to 60 immunolabeled sections per brain or per tissue block ready for microscopic observations.
Procedure: Following cryoprotection, tissue will be rapidly frozen in isopentane pre-cooled to -70°C. The frozen tissue will then be cut on a cryostat and collected in our unique section cryoprotection solution (Slides available upon request). Subsequently, the sections cut from various levels (or the levels of your choice) will be processed free-floating for immunostaining with 1 specific antibody according to immunogold labeling technique¹ (cf. see samples below).
Tyrosine hydroxylase-immunoreactivity in the rat substantia nigra. 30 µm cryostat section cut coronally from the midbrain of a normal rat. This section was processed free-floating according to the immunogold labeling technique. Note densely labeled neurons in the compact area of the substantia nigra.
Tyrosine hydroxylase-immunoreactivity in the rat substantia nigra. The high magnification of the substantia nigra as shown above. Note that dense black deposits in the cytoplasm of neurons are actually metallic silver grains, which can also be viewed under a microscope with a darkfield condenser.
Remarks:
- A quotation is required before placing an order.
- The investigator needs to provide fixed tissue and the specific antibody.
- Please contact us for more information.

This service includes tissue preparation, sectioning, immunolabeling, coverslipping and labeling the slides. As a result, you will receive up to 60 immunolabeled sections per brain or per tissue block ready for microscopic observations.
Procedure: Following cryoprotection, tissue will be rapidly frozen in isopentane pre-cooled to -70°C. The frozen tissue will then be cut on a cryostat and mounted on gelatin-coated microscope slides (Slides available upon request). Subsequently, sections cut from various levels (the levels of your choice) will be processed on slides for immunostaining with 1 specific antibody according to immunogold labeling technique¹.
Remarks:
- A quotation is required before placing an order.
- The investigator needs to provide fixed (or unfixed frozen) tissue and the specific antibody.
- Please contact us for more information.

Bcl2 & parvalbumin double immunostaining. 30 µm cryostat section of the rat cortex was processed free-floating for parvalbumin-immunoreactivity (black deposits) with the immunogold labeling technique and then for bcl2-immunoreactivity according to avidin-biotin-complex method (red).
NeuN & bcl2 double immunostaining. 30 µm cryostat section of the rat cortex was processed free-floating for bcl2-immunoreactivity (black deposits) with the immunogold labeling technique and then for NeuN-immunoreactivity according to avidin-biotin-complex method (red). Note metallic silver grains mainly accumulated in the cytoplasm of bcl2-containing neurons.
GABA & parvalbumin double immunostaining. 30 µm cryostat section of the rat cortex was processed free-floating for parvalbumin-immunoreactivity (black deposits) with the immunogold labeling technique and then for GABA-immunoreactivity (red) according to avidin-biotin-complex method. Note that metallic silver grains are accumulated in both parvalbumin-containing neuronal perikarya and processes (probably axon terminals), many of which surrounds GABA neurons.
