Description

General description

Paraplast Plus^® is a refined mixture of highly purified paraffin containing complex elastomer of regulated molecular weights plus a small percentage of dimethyl sulfoxide (DMSO) for fast tissue penetration. It produces minimal tissue compression and wrinkle-free sections and cuts to 4 μm thickness with excellent ribbon continuity.
Paraplast^® tissue embedding media are made from highly purified wax combined with plastic polymers for tensile strength and elasticity. Paraplast Plus^® provides rapid infiltration during processing as well as great compression resistance during sectioning for preserved morphology and thin, distortion-free sections.
Our range of Paraplast products improve the elasticity of brittle, difficult-to-cut tissues making it easier to produce excellent, wrinkle-free sections.

Application

Paraplast Plus^® is recommended for large specimens and tissue that commonly presents infiltration problems. It has been used:

• in the examination of vertebral specimens of Malacoraja senta.
• in the identification and expression analysis of PIN genes in rice.
• in the study of glucose transport mechanisms in uterine tissues during pregnancy.
• to embed Bouin′s fixed carp tissues, rat ventral prostatic fragments, and common bean (Phaseolus vulgaris L.) nodules.

Features and Benefits

• Produces minimal tissue compression and wrinkle-free sections, and cuts to 4 μm thickness with excellent ribbon continuity.
• 0.8% DMSO enhances ease of infiltration and sectioning for tissues difficult to process with regular Paraplast.
• Higher melt viscosity and lower permeability to water vapor creates better adhesion and a more pliable, flexible film.
• Optimal infiltration and embedding for high-quality sections.
• Great compression resistance and ribbon continuity.
• Remarkable morphology preservation and distortion-free sections.
