Tissue preparation

Tissue cryoprotection & freezing:

Fixed tissue will be infiltrated with our unique tissue cryoprotection solution (cf. Products, Cat. #NDT302) and then rapidly frozen in isopentane precooled to -70°C. The frozen tissue will be stored at -75°C before sectioning.

Remarks:

• A quotation is required before placing an order.
• The investigator needs to provide fixed tissue.

Embedding tissue in paraffin:

Following a thorough wash in distilled water, fixed tissue will be dehydrated through graded ethanol, cleared in xylenes, and then impregnated and embedded in paraffin.

Remarks:

• A quotation is required before placing an order.
• The investigator needs to provide fixed tissue.
• We use various types of paraffin with the melting point ranging from 50-56°C. The investigator may choose the type of paraffin for a particular purpose.
