There are several variations of HIER. Many laboratories have attempted to improve the original method by altering the buffer solutions as well as the source and mode of heating. Currently, the most popular HIER technologies use stainless steel or plastic pressure cookers, microwave ovens, or autoclaves as the heat source and low-molarity buffers with acidic or alkaline pR (6,7,9-12). 

Metallic tools should never be used in a MWO therefore, heat-resistant plastic Coplin jars or containers and heat-resistant plastic slide holders with a capacity of at least 15 sections are required for this application. MWO-medi-ated HIER can also be performed in a plastic pressure cooker designed for household kitchen application (see Subheading 3.2.), which appears to eliminate some of the drawbacks of the standard MWO protocols.

Hoses. Gases for open systems may be carried by ordinary j- or in. gum-rubber tubing. Closed systems may require heavy-wall rubber or plastic pressure tubing, which can safely be used with pressures up to several atmospheres. Warning Do not subject glass apparatus containing bulbs more than 2 or 3 inches in diameter to internal pressures of more than 1 atm above the outside pressure.

DI water is produced using an XYZ rapid, high-performance, twin-bed deionizer. The plant consists of two glass-reinforced plastic pressure vessels that hold the ion exchange resins together with a process pump, pipe work, valves, flowmeters, and controls to enable the plant to produce high-quality deionized water and automatically regenerate the resins. 

Pressure-sensitive adhesives are the essential components of adhesive tapes and labels. They are polymers with permanent tack, usually applied on substrates (plastic/metal films, siliconized papers). To enhance their tack, compounds with high inherent tack are added, for example, resins, plasticizers. Pressure-sensitive adhesives reach their adhesion on the material to be bonded by contact pressure, from which the term pressure-sensitive adhesive (PSA) derives. Apart from electron radiation, also UV-radiation curing described in Section 4.3.2 is applied in adhesive tape manufacturing. The monomer molecules to be polymerized are applied, in liquid form, to the substrates to be coated by rolling and are continuously cured to a polymer layer within seconds under a UV-radiation source. Depending on their composition, predetermined adhesion values can be adjusted. The adhesive tapes can be subsumed under the systems shown in Figure 5.4 ... 

Despite some successes with the above pretreatments, the development of wet heat-induced epitope retrieval (HIER) procedures, which involves heating the fixed tissue sections in dilute metal-salt or buffer solutions at or above 100°C, for several minutes to 1/2 h, was the critical breakthrough in paraffin section immunohistochemistry (2, 7-9). Today, there are many variations of the original HIER technique. These differ primarily in the recommended buffer solutions and/or the source or mode of heating, but the basic formula of wet heat treatment over a fixed time period is similar. The most popular HIER technologies use microwave ovens, stainless steel or plastic pressure cookers, autoclaves, vegetable steamers or water-baths as the heat sources and low molarity buffers with acidic or alkaline pH (8,9,11-14). 

Heating Devices A wide variety of heating devices have been adapted for use in HIER, including microwave ovens (MWO), pressure cookers, vegetable steamers, autoclaves, and water-baths. The most reproducible results may be achieved with MWOs that incorporate time and temperature control even above the atmospheric boiling point (combined with a plastic pressure cooker). The archetypes are the professional laboratory microwave instruments, which...
