Native bovine serum albumin has the surprising property of catalyzing the decomposition of the Meisenheimer complex 1,1-dihydro-2,4,6-trinitrocylohexadienate. Taylor and Silver (1976) prepared albumin fragments 1-306 and 307-581 and separated them without disulfide reduction. These were called native fragments. Neither of these fragments alone has catalytic activity to decompose the Meisenheimer complex, but when mixed together stoichiometrically, 35%... 

AAS is used in a number of limit tests for metallic impurities, e.g. magnesium and strontium in calcium acetate palladium in carbenicillin sodium and lead in bismuth subgallate. It is also used to assay metals in a number of other preparations zinc in zinc insulin suspension and tetracosactrin zinc injection copper and iron in ascorbic acid zinc in acetylcysteine lead in bismuthsubcarbonate silver in cisplatinum lead in oxyprenolol aluminium in albumin solution and calcium, magnesium, mercury and zinc in water used for diluting haemodialysis solutions. 

In addition to the application of roughened Ag electrodes in SERS measurements, one should add that Geddes et al. [15] have described the use of such Ag electrodes in metal-enhanced fluorescence studies also. The constant current flowing between two silver electrodes in pure water facilitated the growth of fractal-like structures on the cathode. The electrode was coated with a monolayer of human serum albumin protein labeled with Indocyanine Green. It was observed that the fluorescence intensity on the roughened electrode increased approximately the 50-fold, compared to the unroughened electrode. 

POUR A FEW DROPS OF THE EGG WHITE SOLUTION ONTO A BRIGHT SILVER COIN. IN A FEW MINUTES SILVER COIN TURNS BROWNISH-BLACK FROM SILVER SULFIDE, PROVING THAT ALBUMIN CONTAINS SULFUR. 

Silver forms several compounds or complexes with proteins by the action of silver oxide with gelatin in alkali solution, or with albumin, or by suspension in casein solution and by other methods, Such silver-protein complexes containing from 19 to 23% of silvei are known as mild silver protein and are used as antiseptic solutions. They are readily soluble in... 

The deposition of silver in tissues is the result of the precipitation of insoluble silver salts, such as silver chloride and silver phosphate. These insoluble silver salts appear to be transformed into soluble silver sulfide albuminates, to bind to or form complexes with amino or carboxyl groups in RNA, DNA, and proteins, or to be reduced to metallic silver by ascorbic acid or catecholamines (Danscher 1981). The blue or gray discoloration of skin exposed to ultraviolet light in humans with argyria may be caused by the photoreduction of silver chloride to metallic silver. The metallic silver is then oxidized by tissue and bound as black silver sulfide (Danscher 1981). Bucklet et al. (1965) identified silver particles deposited in the dermis of a woman with localized argyria as being composed of silver sulfide.

Following rather similar approaches, CdSe-ZnS QDs modified with bovine serum albumin (BSA),38 CdSe/CdS QDs modified by mercaptoethanol,39 and CdTe QDs treated with mercaptopropionic acid40 were proposed for the determination of Cu2+, CdSe QDs modified with mercaptoacetic acid and BSA were assayed for the analysis of silver,41 CdSe/ZnS QDs capped with sulfur calixarene for the determination of... 

More recently 211 At adsorbed on silver coated human serum albumin (HSA) microspheres has been used by Wunderlich, Doberenz and their colleagues46,94-99 to study the accumulation of the isotope in some tumour-bearing tissues of mice and pigs, and in one special case for human therapy100. 

The first enzymatically coupled FET is sensitive to penicillin (1). It is composed of two separate FET chips and a silver/silver chloride reference electrode (see Fig. 4). Penicillinase, which produces protons during catalysis, is immobilized on one of the FET chips by utilizing the glutaraldehyde protein cross-linking reaction. The membrane of the reference FET chip contains immobilized bovine serum albumin. 

Immobilization of DNA on silver surfaces of TSM through modification was reported by Yao and co-workers with thioglycollic acid [55] and didodecyl ditiono-oxamide and bovine serum albumin [56]. The Langmuir-Blodgett (LB) technique was used to deposit ssDNA-containing films on QCM crystals by Nicolini et al. [57] and the nanogravimetric hybridization assay was confirmed by fluorescent measurements. 

After the separation, the proteins are visnalized by staining using Coomassie Brilliant Blue or silver. This represents another hmitation of 2D-GE staining results in a relatively narrow dynamic range, i.e., the relative difference between most and least abundant protein detected. Low-abundance proteins may be completely obscured by high-abundance proteins like albumin and immunoglobulins. For visualization, 10 femtomoles of protein is needed. Procedures have been reported for the selective removal of the high-abundance proteins prior to 2D-GE [10-11].
