Benzylpenicilloyl polylysine
Benzylpenicilloyl polylysine (also known as Pre-Pen) is a diagnostic agent used in skin testing to evaluate sensitization to penicillin in humans. It is a major determinant of penicillin allergy and is used to predict an allergic response to penicillin therapy.
History[edit | edit source]
The development of benzylpenicilloyl polylysine was a significant advancement in the field of allergy and immunology. It was first introduced in the 1960s as a diagnostic tool for penicillin allergy.
Structure and Properties[edit | edit source]
Benzylpenicilloyl polylysine is a large, water-soluble molecule. It is composed of a benzylpenicilloyl group attached to a polylysine backbone. The benzylpenicilloyl group is the major determinant for penicillin allergy, while the polylysine backbone provides the molecule with its water-soluble properties.
Use in Allergy Testing[edit | edit source]
Benzylpenicilloyl polylysine is used in skin testing to evaluate sensitization to penicillin. The test is performed by injecting a small amount of the substance under the skin and observing for a reaction. A positive reaction indicates a high likelihood of penicillin allergy.
Safety and Efficacy[edit | edit source]
Benzylpenicilloyl polylysine has been shown to be safe and effective in predicting penicillin allergy. However, like all diagnostic tests, it is not 100% accurate and should be used in conjunction with a thorough medical history and other diagnostic tools.
