productive cell infection may be controlled at the membrane level‚ requiring the interaction of a specific cellular receptor with the virus envelope‚ as demonstrated recently for Epstein–Barr virus (EBV)1. Therefore‚ we have investigated whether the T4 molecule itself is related to the receptor for LAV. We report here that preincubation of T4+ lymphocytes with three individual monoclonal antibodies directed at the T4 glycoprotein blocked cell infection by LAV. This blocking effect was specific‚ as other

Arndt’s study implies‚ even if a membership in a particular group is important‚ if it affects their self-esteem; they are likely to distance themselves from that particular group‚ especially if mortality is induced. This suggests that people are more focused on self-esteem than belonging to a group. It would be interesting to see if the extent of group identification contributes the disengagement of a particular group. For example‚ the difference between people who were raised highly accustomed to

variety of qualities and ingredients in their protein supplements. A brand of protein powder‚ “Tough Guy”‚ claims that if a person were to dilute 1 gram of protein powder in 100ml of water‚ the final concentration should be approximately 0.40 mg/ml (+/- 5%) protein. The objective of this experiment is to determine whether the manufacturer is telling the truth. MATERIALS AND METHODS One gram of Tough Guy protein powder was added to 100 ml of water. 50 µl of the sample was added to respective test tubes:

Physical Properties of Organic Molecules Abstract Identifying the physical properties of compounds can be useful in several ways. It helps us to determine the structure of certain compounds‚ the purity of substances and if a substance is not pure we can figure out how to separate contaminating substances from a compound. In this experiment‚ I learned how to determine a solid’s melting point and why some melting point ranges may be broader than others.
