Abstract
Human sera have been examined for antibodies with specific reactivity for γE using the tanned cell hemagglutination test. Cells tanned with three different γE myeloma proteins provided a reproducible test system. Inhibition of agglutination reactions by γE proteins, but not by γG, γA, γM, or γD confirmed the specificity of these reactions. 8.5% of 304 serial serum samples obtained from miscellaneous hospitalized patients showed clear-cut anti-γ-globulins with specificity for γE. In most of these instances no definite clinical history of concomitant allergic disorders could be obtained. 53% of 73 patients with well-established allergic disorders (hay fever, extrinsic asthma) showed serum anti-γ-globulins with reactivity for γE. Some patients studied before and after desensitization to Bermuda grass allergen showed an increase in titer or a conversion from negative to positive reactions for anti-γE antibodies following several month courses of progressive desensitization. Gradient and gel filtration studies indicated that anti-γE globulins were 19S γM in all instances. No clear correlation was noted between quantitative serum γE levels and titer of anti-γE antibodies.

Usage information is collected from two different sources: this site (JCI) and Pubmed Central (PMC). JCI information (compiled daily) shows human readership based on methods we employ to screen out robotic usage. PMC information (aggregated monthly) is also similarly screened of robotic usage.
Various methods are used to distinguish robotic usage. For example, Google automatically scans articles to add to its search index and identifies itself as robotic; other services might not clearly identify themselves as robotic, or they are new or unknown as robotic. Because this activity can be misinterpreted as human readership, data may be re-processed periodically to reflect an improved understanding of robotic activity. Because of these factors, readers should consider usage information illustrative but subject to change.
