  • Immunoassay for venom detection including noninvasive sample collection
    Patent number: 8426154
    Abstract: Methods and immunoassays for diagnosing a bite or sting of a venomous organism in a patient having symptoms consistent with such a bite or sting are provided. A sample of venom is collected from the area of the suspected bite or sting using a swab and then contacted with an antibody that specifically binds to an antigenic site on venom present in the sample. Binding is then detected. The invention is illustrated by examples showing diagnosis of brown recluse spider bite, distinguishing it from other diagnoses with which it is often confused. This extremely sensitive test can detect venom antigens down to about 20 picograms even after the sample has been shipped and stored for periods of up to three weeks during the summer.

  • Treatment of human plasma with brown recluse spider toxin to emulate a lupus anticoagulant
    Patent number: 4877741
    Abstract: A new method for improving the accuracy of blood tests for the presence of lupus anticoagulants and for blood factor deficiencies is disclosed. Brown recluse spiders are collected, their venon glands removed by microdissection and the active toxin extracted. The toxin is mixed with normal donor plasma in concentrations of about 3.5 .mu.l/ml of toxin to plasma. The treated plasma successfully mimics human plasma having lupus anticoagulants. By using the treated plasma in blood tests and assays as a standardized control to which the results from tests on questioned blood plasma samples may be compared, the equipment and procedures for those tests may be calibrated and test results made more sensitive and reliable.
