Individual animals immunized with the same substance can produce antibodies that may differ in affinities, titer, and specificities. " Such differences are appeu-ent with antibodies studied by the more classical physical chemical procedures. However, even among anti-enzyme sera harvested from individual rabbits that had been immunized with -lactamase, some were found to neutralize the activity of the enzyme, others to stimulate its activity, and still others were stimulatory and then inhibitory at higher concentrations." In radioimmunoassay, each antiserum from an individual animal must be characterized separately to select those that have the proper affinities and specificities. The production of monoclonal antibodies by hybridoma technology can yield molecules with defined specificities and affinities. As this technology becomes affordable for the average research laboratory, problems associated with antibody heterogeneity are due to diminish.

The triacylglycerol (TG)-rich lipoproteins (very low density lipoproteins (VLDLs) and chylomicrons (CM)) are secreted into the circulation by hepatocytes of the liver and ente-rocytes of the intestine. All plasma lipoproteins share a common structure with a neutral lipid core, consisting of TGs and cholesteryl esters, surrounded by a surface monolayer of...

Fourlfa, the i ent may dissolve into die aTSP during exposure and not be completely removed by die cleaning procedure. The cleaning procedure following HD vt r eiqposure involves wiping each site with two dry foam-covered cotton swabs. This process removes most of die aTSP but a small film still remains on die skin surface (2d). If HD dissolved into die aTSP and was not completely neutralized, a small amount could have been in contact with the skin surfiice until the postexposure readings were made (24 hr). 

An RCD is a type of circuit-breaker that continuousiy compares the current in the iine and neutrai conductors of the circuit. The currents in a healthy circuit wiii be equai, but in a circuit that deveiops a fault, some current will flow to earth and the line and neutral cun ents will no longer balance. The RCD detects the imbalance and disconnects the circuit. Figure 3.33 shows an RCD s construction.

Radical-molecule reactions have been more extensively studied than any other class of bimolecular reaction between neutral species. Accurate rate constants have been measured for many reactions in the limited tenperature range between ca 220 and 500 K [3], and for a fair fraction of these reactions rate data exist for T > 500 K. Positive activation energies are the rule, with values usually between 0 and 50 kJ mol . Rate measur ents below 200 K are very rare. Extrapolation of rate constants to the very low temperature of interstellar clouds is unlikely to be accurate but in virtually all cases it seems safe to assume that the rates will be too small for the reactions to be significant. 

In general this resonance will stabilize the excited states even more than the ground states of the molecules, allowing absorption to occur at long wavelengths well into the visible region. The neutral spectrum of a porphyrin (Fig. 3) consists of an intense absorption band near 400 mM, the Soret band (E l-3 X 10 ), and a series of four bands between 480 and 650 m/z (Eni 10 ). In acid solution the Soret band is intensified (Ent 5 X 10 ) and the series of four bands is reduced to two bands lying between 530 and 600 mu (Em 10 ). Several theoretical interpretations of these spectra have been attempted (lS-16).
