Abstract: A new method based on the synthesis and use of novel N and C protecting agents. The new N-protecting agent, here referred to as V-Phenol, generates V-protected amino acids and can be successfully applied to all conventional peptide bond formations including active esters, N,N?-dicyclohexylcarbodiimide (DCC) or related dehydrating agents mixed anhydride methods, PC13 and related agents. The new C-protecting agent, here referred to as HONE, can be successfully applied to peptide synthesis as an active ester not only in combination with V-protected amino acids but also with other N-protecting agents such as Cbz, Boc, Fmoc, etc.

Abstract: A process for the detection of antibodies in a test sample by preparing a suspension of erythrocytes with a test serum or plasma by mixing a test serum or plasma with erythrocytes; incubating the suspension of erythrocytes at a temperature of from 37° C. to 45° C. to bind any antibodies in the test serum or plasma to the surface of said erythrocytes; combining the suspension of erythrocytes with an amount of a solution of a macromolecule which is effective to agglutinate the erythrocytes; packing the resultant red cell agglutinates by centrifuging the suspension of erythrocytes; and, determining the presence of anti-erythrocyte antibodies by observing if antibody-dependent erythrocyte agglutination has occurred.

Abstract: A process for the detection of antibodies in a test sample by carrying out the following steps: (a) preparing a suspension of erythrocytes with a test serum or plasma by mixing a test serum or plasma with erythrocytes; (b)incubating the suspension formed in step (a) at a temperature of from 37° C. to 45° C. for a period of time from sixty seconds to 10 minutes to bind any antibodies in the test serum or plasma to the surface of said erythrocytes (c)combining said suspension with an amount of a solution of a macromolecule which is effective for agglutination of said erythrocytes; (d) packing the resultant red cell agglutinates by centrifugation from the suspension of step (c); and, (f) determining the presence of anti-erythrocyte antibodies by observing if antibody-dependent erythrocyte aggregation has occurred.

Abstract: A process for the detection of antibodies in a test sample by carrying out the following steps: (a) preparing an essentially isotonic and low ionic strength suspension comprising said test sample and erythrocytes; (b) incubating the erythrocytes, test sample and low ionic strength medium at 37-45° C. for various time periods to optimize antibody uptake; (c) combining said suspension with an amount of a solution of hexadimethrine bromide which is effective for agglutination of said erythrocytes and (d) separating the resultant agglutinates of polymer and erythrocytes from said suspension; (e) neutralizing the effect of hexadimethrine bromide by adding an effective amount of a gylcosaminoglycan in combination with other polybrene neutralizing agents; (f) monitoring the resuspended agglutinates for the presence or absence of antibody; (g) stabilizing the antibody dependent aggregate by adding an effective macromolecule as a component of the dispersing solution or separately and optionally.

Abstract: The present invention provides a chemically modified form of hemoglobin that is stabilized and can efficiently bind and release oxygen. In addition the chemically modified hemoglobin may be polymerized to increase its molecular weight and increase its stability so that it will have a longer half life in the circulatory system and may be used as a stable oxygen transport mediator which is useful as the basis of a blood substitute.

Abstract: A process for the detection of antibodies in a test sample is described. This process involves:(a) preparing an essentially isotonic and low ionic strength suspension comprising said sample and erythrocytes in net negatively-charged form;(b) maintaining said suspension for at least 30 seconds;(c) combining said suspension with an amount of a solution of polymer effective for agglutination of said erythrocytes;(d) separating the resultant agglutinates of polymer and erythrocytes from supernatant of said suspension;(e) dispersing said agglutinates in a hypertonic salt solution having an essentially neutral pH; and(f) monitoring the dispersed agglutinates for dissociation of erythrocytes.This process permits rapid detection of antibodies with great ease. Their presence is indicated by persistence of the agglutinates in the dispersion. The antigen which reacts with antibody may be native to the erythrocytes, or may be unrelated to erythrocytes but artificially coupled to those cells.
