Percent light chain

Integration of the electropherogram for an antibody to quantify main protein species percent light chain and heavy chain (%LC and %HC) and minor species such as percent non-main and percent high molecular weight species (%non-main species and %HMW) is shown in Figure 5. Corrected peak areas were used for quantification. The % corrected peak area is defined as ... 

Figure 1. Sequences of acrosin light chains and N-terminal sequences of acrosin heavy chains shown aligned with the sequences of corresponding portions of other serine proteases. Positions identical with the porcine acrosin sequence are underlined. Alignments for plasmin, prothrombin, Clr b-chain, cathepsin G, and plasminogen activator are from (24), except minor adjustments were made to maximize similarity with acrosin. Sequence similarities expressed as percent positional identity to the porcine sequences are indicated to the right of each sequence. Abbreviations po - porcine, ca - caprine, bo - bovine, hu - human.

Cosolvents and Tri-n-butyltin Fluoride. Dunn and Oldfield (15) first reported the ability of tri-n-butyltin fluoride to dramatically increase the viscosity of a relatively light alkane, namely hexane. Tri-n-butyltin fluoride exists in the form of a penta co-ordinate species, and is thereby able to form linear polymer chains by weak dipole-dipole interactions between the fluorine and tin of adjacent molecules. The fluid in which the tri-alkyltin fluoride is dissolved must have no dipole moment in order not to disrupt the transient associations which form the long chain polymer. As stated earlier, this compound was only very slightly soluble in CO2 (less than two weight percent) and no viscosity increase was observed. Heller et at. (2, 7) have conducted extensive research on these tri-alkyltin fluorides varying the alkyl groups in an attempt to enhance their solubility in 002 ... 

The nuclear fuel consists of uranium, usually in the form of its oxide, U3O8 (Figure 23.12). Naturally occurring uranium contains about 0.7 percent of the uranium-235 isotope, which is too low a concentration to sustain a small-scale chain reaction. For effective operation of a light water reactor, uranium-235 must be enriched to a concentration of 3 or 4 percent. In principle, the main difference between an atomic bomb and a nuclear reactor is that the chain reaction that takes place in a nuclear reactor is kept under control at all times. The factor limiting the rate of the reaction is the number of neutrons present. This can be controlled by lowering cadmium or boron rods between the fuel elements. These rods capture neutrons according to the equations... 

One percent (w/w) hydrophobic cholesteryl 4-(2-anthryloxy) butyrate in hydrocarbons and long-chain alcohol solvents produces solid gels. Weak CD spectra indicate helix formation. A steroid with a piperidine D-ring dissolved in cyclohexane shows a fiber network under the polarizing light microscope (Fig. 3.5.5). 

The oxidation of methane and other light alkanes in the gas phase at high temperature gives alcohols, aldehydes and ketones and occurs via a chain radical mechanism (for certain stages of the process, see recent publications [30]). The methane oxidation produces methanol and formaldehyde as main oxygenates. Due to the fact that both products are much more reactive than hydrocarbon, the yield of alcohol and aldehyde is only a few percents. Usually the reactions were...
