Protein gold complexes are prepared by adding gold colloids to cytochemically active proteins in solution. The gold particles of the colloid form complexes with the protein spontaneously, but some of the protein remains uncomplexed. Currently, when protein A-gold complexes are prepared, the uncomple

β¦ Synopsis
The isolation of elastin from various tissues has depended upon its chemical inertness and resistance to hydrolysis. However, the majority of the procedures used to obtain a purified product are drastic enough that breakdown of elastin occurs. This communication describes a new method for the isolation of elastin with less degradation than existing methods. The tissue is milled through a 40 mesh screen in a Wiley Mill. It is extracted with guanidinium chloride, autoclaved, and then treated with formic acid-cyanogen bromide. A purified product is obtained and quantitation of NH~-terminal residues shows five to ten times less end-groups than elastin extracted with currently existing methods.

A method is described for the rapid purification of acid deoxyribonucleases. It primarily involves chromatography of the enzyme-containing preparation through a DNA-ECTEOLA-cellulose column. This column retains the DNAse activity but not the inactive protein, and consequently, high degrees of purifi
## Abstract The demand for recombinant proteins for medical and industrial use is expanding rapidly and plants are now recognized as an efficient, inexpensive means of production. Although the accumulation of recombinant proteins in transgenic plants can be low, we have previously demonstrated that
