Peptone

Is it _pepsin_, the active principle of the gastric juice, which converts proteids into peptone, that is wanting, or is there a deficiency of _pancreatin_? ❋ Ray Vaughn Pierce (1877)

With weaker doses of antigen and with antigens that are harmless or practically so, such as peptone, the anaphylactic leucocytosis does not last as long but is nevertheless pronounced. ❋ Unknown (1967)

To mention examples, blood serum solidified at a suitable temperature is a highly suitable medium, and various media are made with extract of meat as a basis, with the addition of gelatine or agar as solidifying agents and of non-coagulable proteids (commercial "peptone") to make up for proteids lost by coagulation in the preparation. ❋ Various (N/A)

This is because the pancreatic ferment (trypsin) has digested the casein into "peptone," which does not curdle. ❋ Albert F. Blaisdell (N/A)

Two hours later, Neil Noakes scraped a heavily inoculated 4 day culture plate of Helicobacter and dispersed the bacteria in alkaline peptone water a kind of meat broth used to keep bacteria alive. ❋ Siddhartha Mukherjee (2010)

I won't say a word until I get some peptone into my arteries. ❋ Various, (1973)

A quantity of peptone equal to 0.005 per kilo live weight will still give leucocytosis and bring about either immunity or anaphylaxis. ❋ Unknown (1967)

He began his investigations into the constitution of the cell nucleus at the end of the seventies, and in the nineties he turned more and more to the study of the proteins, the alterations in proteins during transformation into peptone, the effects of a phenetol diet on the urine, the peptonic components of the cells, the simplest proteins, etc. ❋ Unknown (1967)

A certain degree of non-specific immunity or increased tissue resistance may be produced locally, _e. g._ in the peritoneum, by injections of non-pathogenic organisms, peptone, nucleic acid and various other substances. ❋ Various (N/A)

For example, various sugars -- lactose, glucose, saccharose, &c. -- are added to test the fermentative action of the bacterium on these substances; litmus is added to show changes in reaction, specially standardized media being used for estimating such changes; peptone solution is commonly employed for testing whether or not the bacterium forms indol; sterilized milk is used as a culture medium to determine whether or not it is curdled by the growth. ❋ Various (N/A)

It is, indeed, a true milk peptone -- that is, milk already partly digested, the coagulation of the coagulable portion being loose and flaky, and not of that firm indigestible nature which is the result of the action of the gastric juice upon cow's sweet milk. ❋ Mrs. F.L. Gillette (N/A)

Wash the peptone emulsion into a flask with 800 c.c. distilled water, and heat in the steamer at 100° C. for twenty minutes. ❋ Unknown (N/A)

Weigh out Witté's peptone, 10 grammes, and salt, 5 grammes, and emulsify with about 250 c.c. of distilled water previously heated to 60° ❋ Unknown (N/A)

The proteids of flesh, like those of vegetables, are converted into peptone by the digestive juices -- taking the form of a perfectly diffusible liquid -- otherwise they could not be absorbed and utilised by the body. ❋ A. W. Duncan (N/A)

It helps digest fatty matters by its emulsive powers; it has been more recently supposed to form a sort of _peptone_ with nitrogenized articles also; but, what is more to our purpose, it turns starch into sugar even more quickly than the saliva itself. ❋ Various (N/A)

Thus prepared, the peptone shows no signs of decomposition on keeping. ❋ Various (N/A)

The reagent is prepared by dissolving 30 grains of flesh peptone, 4 grains of salicylic acid, and 30 minims of strong acetic acid, in sufficient water to produce 8 fluid oz. of solution. ❋ Various (N/A)

Dr. Oliver, of Harrogate, has proposed the use of an acidulated peptone solution for this purpose, and the reaction is undoubtedly a good one. ❋ Various (N/A)
