These peculiar features are essential in developing a RIA procedure for l l-dehydro-TxB2, since a carboxyl group in position l l represents a strong antigenic determinant influencing the immune response in animals as well as the affinity and specificity of antisera.

4 kV. 0 × 10 -6 torr. A small amount of calibration gas (FC 43) is introduced into the calibration gas line through the automatic solenoid valve. It is then allowed to pass into the mass spectrometer by carefully opening an in-line Nupro SS-4BRW (Nupro, Willoughby, OH) needle valve. Great care is taken to avoid contamination of the mass spectrometer source with excess FC 43. 25 mA and tuning carried out on the ion at m/z 633. The electron energy is optimized for maximum sensitivity (60-90 eV, depending on the cleanliness of the source) and the source controls are then tuned for maximum sensitivity.
