An immunoenzyme assay for quantitation of human IgG antibodies to honeybee venom phospholipase A2

Journal of Immunological Methods
R P TracyH A Homburger


A new method to measure the concentrations of IgG antibodies to phospholipase A2 in sera from patients treated with honeybee venom immunotherapy is described. This method utilizes a microcentrifugal analyzer to detect inhibition of PLA2 enzymatic activity by antibodies in serum standards and unknowns. Sera from beekeepers with known concentrations of specific antibodies, measured by radioimmunoprecipitation, were used to construct a logit-log standard curve for the immunoenzyme assay. The standard curve was linear for concentrations between 2.3 and 20.0 microgram/ml. The concentrations of specific antibodies measured by enzyme inhibition correlated well with the concentrations as measured by radioimmunoprecipitation, r = 0.959 (least squares linear regression), n = 32. Interassay variation was 10.1% at 10 microgram/ml. The immunoenzyme method is rapid and does not require radiolabeled reagents.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Lipidomics & Rhinovirus Infection

Lipidomics can be used to examine the lipid species involved with pathogenic conditions, such as viral associated inflammation. Discovered the latest research on Lipidomics & Rhinovirus Infection.

Glut1 Deficiency

Glut1 deficiency, an autosomal dominant, genetic metabolic disorder associated with a deficiency of GLUT1, the protein that transports glucose across the blood brain barrier, is characterized by mental and motor developmental delays and infantile seizures. Follow the latest research on Glut1 deficiency with this feed.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Alzheimer's Disease: MS4A

Variants within the membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease in genome-wide association studies. Here is the latest research on Alzheimer's disease and MS4A.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
