Immunofixation of complement component C3 phenotypes in bloodstains after cellulose acetate electrophoresis

The determination of the polymorphic C3 phenotypes was accomplished by electrophoresis on cellulose acetate followed by immunofixation. The three common phenotypes resulting from the two common codominant alleles C3S and C3F were clearly distinguishable in blood and bloodstain samples. Storage and degradation of C3 in blood samples as well as the stability of C3 in dried bloodstains is discussed.     

Building a U.S.-Soviet working relationship

Conclusion The crucial determinant of U.S. and Soviet security, and the security of the world, will not depend on technological development, breakthroughs in deterrence theory, or even on agreements the two countries might sign at the summit talks. The future depends on whether the two governments are able to work together.Both the United States and the Soviet Union have developed procedures for solving conflicts with other governments, even former enemies, without hostilities or threats of force. The essential difference between these relationships and the U.S.-Soviet relationship lies not in the degree of difference in cultural heritage or security interests, but in the way the two governments approach their problems—through consultations and dispute resolution procedures, or through conflict and recrimination.The process of interaction is the essence of a working relationship. It means the difference between hostile confrontation and constructive collaboration, between fear and security, between war and peace. The summit meeting provides an opportunity to change the nature of the relationship, to change the focus of U.S.-Soviet interaction from antagonistic bargaining over divisive issues to constructive collaboration on possible solutions and working procedures.
