NDT401-ba Tissue preparation & immunofluorescence labeling with 1 primary antibody on free-floating sections

Tissue preparation & immunofluorescence labeling with 1 primary antibody on free-floating sections

This service includes tissue preparation,  sectioning, immunostaining, mounting, coverslipping and labeling the slides. As a result, you will receive up to 60 immunostained sections per brain or per tissue block ready for microscopic observations. To express our appreciation, a set of Nissl (or H & E) stained sections adjacent to those used for immunostaining will also be provided for you without additional cost.

Procedure: Following cryoprotection, tissue will be rapidly frozen in isopentane pre-cooled to -70¢XC. The frozen tissue will then be cut on a cryostat and collected in our unique section cryoprotectionsolution (cf. Product NDT301). Subsequently, sections cut from various levels (or the levels of your choice) will be processed free-floating for immunostaining with 1 specific antibody according to the indirect immunofluorescence method1( cf. photo samples below).



Confocal image of BrdU-immunoreactivity. 30 £gm cryostat section was cut from the hippocampal dentate gyrus of a mouse that survived for 24 hr after the injection with 5-bromo-2-deoxyuridine (BrdU). This section was processed free-floating according to the indirect fluorescence method.

Confocal image of NeuN-immunoreactivity. The same section as shown above was processed free-floating for NeuN-immuoreactivity according to the indirect fluorescence method. Note NeuN-labeled granule cells and polymorphic neurons in the dentate gyrus.

Colocalization of BrdU- and NeuN- immunoreactivities. A digital overlay of the 2 images shown above. Note that the regions of colocalization, reflecting the additive effect of superimposed green and red pixels, appear in yellow.

Remarks:
1. A quotation is required before placing an order.
2. The investigator needs to provide fixed tissue and the specific antibody.
3. Please contact us for more information.
