  • (20) The capsule was identified by precipitation against hexadecyl trimethylammonium bromide (Cetavlon), by demonstration of iridescence, and by means of a capsule-staining method.

Opalescent


Definition:

  • (a.) Reflecting a milky or pearly light from the interior; having an opaline play of colors.

Example Sentences:

  • (1) Among both exposed and non-exposed aged over 45, there were no significant differences with regard to the characteristics of lens opacities--prevalence (19 in the 21 exposed; 10 in the 16 non-exposed), distribution of the location, and importance and type (opalescence or discontinuous opacities).
  • (2) The severity of nuclear opalescence (NO), cortical (C) and posterior subcapular cataract (P) was graded in a masked fashion using the LOCS II standards.
  • (3) The rate of this reaction can be estimated roughly from the initial rate (Vo) of the accompanying turbidity increase ("super-opalescence") of the acto-S-1 solution.
  • (4) This may indicate that there is considerable variation in inheritance patterns for hereditary opalescent dentine and that this trait does not always exhibit 100 percent penetrance.
  • (5) Furthermore, selenite induced the gradual development of opalescence and the oxidation of sulfhydryl in the lens protein solution.
  • (6) At pH 1-7 the alpha-particles dissociated into their constituent beta-particles with a consequent decrease in the opalescence of the solution.
  • (7) A family is described in which two females are more severely affected by hereditary opalescent dentine than the males.
  • (8) Prednisolone-induced aggregates result in an opalescence in the crystallins solution which is reversed by the addition of dithiothreitol.
  • (9) Residual Triton X-100 was removed from the opalescent vesicle suspension by sucrose density gradient centrifugation and subsequent dialysis.
  • (10) Shortcomings in previous attempts have been corrected by objectively aligning a "blind" eye with the center of a translucent opalescent screen.
  • (11) A potential of 100 V was applied for 12 hours, then raised to 200 V for another 12 hours, and finally to 300 V until opalescence appeared at the bottom of the tube.
  • (12) Colonies of C. perfringens on LLA had typical opalescent zones, a distinctive feature that can aid in presumptive identification.
  • (13) The presence of the regulatory light chain did not affect hyper-opalescence (or super-opalescence), since there were no significant differences between papain S-1 and chymotryptic S-1 with respect to these phenomena.
  • (14) We conclude that the most likely mechanism responsible for the zones is a light-scattering effect caused by antibodies attached to the viral surface and that the quality of the opalescence to some extent seems to be dependent on the Fc-fragment.
