Allergens in Hymenoptera venom XIII: Isolation and purification of protein components from three species of vespid venoms

The Journal of Allergy and Clinical Immunology
D R Hoffman


Pure venoms were collected from individual insects of the species Dolichovespula maculata, white-faced hornet, Vespula squamosa, southern yellow jacket, and Polistes exclamans, paper wasp (one species). The venoms were first fractionated by high-resolution gel filtration on a 1.6 m column of Sephadex G-75 superfine, and the components were then purified by high-performance, ion-exchange chromatography on a Mono-S cation exchange column followed by a further gel filtration step. The isolated components were evaluated for purity by sodium dodecyl sulfate polyacrylamide gel electrophoresis by use of two different types of silver stains, by assays for enzyme activities, and by immunodiffusion with the use of rabbit antisera. The protein components were isolated in highly purified states by these techniques. Only three significant proteins were found in V. squamous venom: phospholipase (PL) A and B, hyaluronidase (HYAL), and antigen 5 (Ag 5). D. maculata venom contained HYAL, Ag 5, two isozymes of PL A and B, a high-molecular-weight protein, and several trace proteins. No significant amounts of proteases were found in D. maculata venom. P. exclamans venom contained HYAL, PL A and B, Ag 5, a high-molecular-weight protein, and several...Continue Reading

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.


Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

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.

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.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

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.


Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
