Antigen Antibody Reaction of Cell Memberane and Related Substances

the evaluation of language related engagment and task related engagment with the purpose of investigating the effect of metatalk and task typology

abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...

Factors affecting the antigen-antibody reaction.

Types of weak interactions According to quantum mechanics, all chemical bonds are based on electrostatic forces. A list of types of weak bonds is shown in table I, together with their strength (energy). Van der Waals forces are the weakest, but they are able to attract all kinds of molecules. Hydrogen or iondipole bonds require oppositely charged atoms. Hydrogen bonds are very important in aque...

The antibody-antigen reaction: a visual observation.

An isologous antigen-antibody reaction with human neutrophiles, related to neonatal neutropenia.

Development of methods for detection of leukocyte antigens has made possible the classification of human leukocytes into different antigenic types, distinct from those of erythrocytes. To date several such antigen systems have been described (1-4). Studies on the distribution of some of these antigens in various blood cells have indicated that they are present in both granulocytic and nongranul...

Biochemical Study of Cellular Antigen-antibody Reaction in Tissue Culture

The correlation between morphological and biochemical changes produced by the antigen-antibody reaction was studied in cultures of tissue monocytes taken from sensitized animals. The cells were grown under conditions which allowed collection of samples from the culture fluid as well as microscopic observation. Introduction of the antigen into the culture medium causes rapid release of a proteas...
