A NEW MARAGLAS, D.E.R.® 732, EMBEDMENT FOR ELECTRON MICROSCOPY

Abstract

A new epoxy embedding mixture for biological material recently has been introduced by Freeman and Spurlock (1). This mixture consists of Maraglas 655, Cardolite NC-513, dibutyl phthalate, and the curing agent benzyldimethylamine (BDMA). Maraglas has certain advantages over other resins and epoxies, notably, wide range of miscibility, low viscosity, ease of sectioning, good staining qualities, beam stability, and little background granularity. Although improvements have been made in the original technique (2), certain problems remain. The Maraglas mixture penetrates tissue very slowly, makes the tissue quite brittle, and has variable polymerization properties. In this paper the use and advantages of a new polyglycol type flexibilizer as a replacement for Cardolite NC-513 in a Maraglas 655 epoxy formulation will be presented.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
