Protein measurement with the Folin phenol reagent

Protein measurement with the Folin phenol reagent ~ PROTEIN MEASUREMENT WITH THE FOLIN PHENOL REAGENT* BY OLIVER H. LOWRY, NIRA J. ROSEBROUGH, A. LEWIS FARR, AND ROSE J. RANDALL (From the Department of Pharmacology, Washington University School oj Medicine, St. Louis, Missouri) (Received for publication, May 28, 1951) Since 1922 when Wu proposed the use of the Folin phenol reagent for the measurement of proteins (l), a number of modified analytical pro- cedures ut.ilizing this reagent have been reported for the determination of proteins in serum (2-G), in antigen-antibody precipitates (7-9), and in insulin (10).

Although the reagent would seem to be recommended by its great sen- sitivity and the simplicity of procedure possible with its use, it has not found great favor for general biochemical purposes. In the belief that this reagent, nevertheless, has considerable merit for certain application, but that its peculiarities and limitations need to be understood for its fullest exploitation, it has been studied with regard t.o effects of variations in pH, time of reaction, and concentration of react- ants, permissible levels of reagents commonly used in handling proteins, and interfering subst.ances. Procedures are described for measuring protein in solution or after precipitation wit,h acids or other agents, and for the determination of as little as 0.2 y of protein. Method Reagents-Reagent A, 2 per cent N&OX in 0.10 N NaOH. Reagent B, 0.5 per cent CuS04.5Hz0 in 1 per cent sodium or potassium tartrabe. Reagent C, alkaline copper solution. Mix 50 ml. of Reagent A with 1 ml. of Reagent B. Discard after 1 day. Reagent D, carbonate-copper solution, is the same as Reagent C except for omission of NaOH.

Reagent E, diluted Folin reagent. Titrate Folin-Ciocalteu phenol reagent ((II), Eimer and Amend, Fisher Scientific Company, New York) with NaOH t.o a phenolphthalein end-point. On the basis of this titration dilute the Folin reagent (about 2-fold) to make it 1 N in acid. Working standards may be prepared from human serum diluted IOO- to lOOO-fold (approximately 700 to 70 y per ml.). These in turn may be checked against a standard solution of crystalline bovine albumin (Armour and * Supported in part by a grant from the American Cancer Society on the recom- mendation of the Committee on Growth of the National Research Council.

On the evolution of random graphs pdf

On the evolution of random graphs pdf ~ ON THE EVOLUTION OF RANDOM GRAPHS by P. ERDŐS and A. RÉNYI Dedicated to Professor P. Turán at his 50th birthday. Introduction Our aim is to study the probable structure of a random graph rn N which has n given labelled vertices P, P2, . . . , Pn and N edges; we suppose that these N edges are chosen at random among the l n 1 possible edges, 2 so that all ~ 2 = Cn,n possible choices are supposed to be equiprobable . Thus 1V if G,,,,, denotes any one of the C,,N graphs formed from n given labelled points and having N edges, the probability that the random graph -Pn,N is identical with G,,,N is 1 . If A is a property which a graph may or may not possess, Cn,N we denote by PnN (A) the probability that the random graph T.,N possesses the property A, i. e. we put Pn,N (A) = An ' N where An,N denotes the Cn N number of those Gn,N which have the property A . An other equivalent formulation is the following : Let us suppose that n labelled vertices P,, P2, . . ., Pn are given. Let us choose at random an edge among the l n I possible edges, so that all these edges are equiprobable. After 2 this let us choose an other edge among the remaining In - 1 edges, and continue this process so that if already k edges are fixed, any of the remaining (n) - k edges have equal probabilities to be chosen as the next one . We shall 2 study the "evolution" of such a random graph if Nis increased. In this investi- gation we endeavour to find what is the "typical" structure at a given stage of evolution (i. e. if N is equal, or asymptotically equal, to a given function N(n) of n). By a "typical" structure we mean such a structure the probability of which tends to 1 if n -* + - when N = N(n). If A is such a property that lim Pn,N,(n) (A) = 1, we shall say that „almost all" graphs Gn,N(n) n--- possess this property. Download On the evolution of random graphs pdf
