An improved spectrally sensitized ultrathin tabular grain emulsion is disclosed in which tabular grains (a) having {111} major faces, (b) containing greater than 70 mole percent bromide and at least 0.25 mole percent iodide, based on silver, (c) accounting for greater than 90 percent of total grain projected area, (d) exhibiting an average equivalent circular diameter of at least 0.7 .mu.m, (e) exhibiting an average thickness of less than 0.07 .mu.m, and (f) having latent image forming chemical sensitization sites on the surfaces of the tabular grains, are spectrally sensitized. The speed-granularity relationship of the emulsion is improved by employing in forming the surface chemical sensitization sites at least one silver salt epitaxially located on tabular grain surface sites that contain increased iodide concentrations.A photographic element is disclosed comprised of a support, a first silver halide emulsion layer coated on the support and sensitized to produce a photographic record when exposed to specular light within the minus blue visible wavelength region of from 500 to 700 nm, a second silver halide emulsion layer capable of producing a second photographic record coated over the first silver halide emulsion layer to receive specular minus blue light intended for the exposure of the first silver halide emulsion layer, the second silver halide emulsion layer being capable of acting as a transmission medium for the delivery of at least a portion of the minus blue light intended for the exposure of the first silver halide emulsion layer in the form of specular light, wherein the second silver halide emulsion layer is comprised of the improved spectrally sensitized ultrathin tabular grain emulsion of the invention.The ultrathin tabular grain emulsions with silver salt epitaxy chemical sensitization have been observed to produce larger than expected speed increases, to produce higher than expected contrasts, to be unexpectedly specularly transmissive and therefore compatible with forming sharp photographic images in underlying emulsion layers, to exhibit a higher percentage of total light absorption in the wavelength region of maximum absorption by the spectral sensitizing dye or dyes employed, and to exhibit a surprising tolerance of inadvertent manufacturing variances.

A process is disclosed for the precipitation of a silver halide emulsion containing host grains having {100} crystal faces that are sensitized by the deposition of protrusions at the intersections of the {100} crystal faces. Protrusion growth is achieved by undertaking final silver introduction in the presence of a benzothiazolium site director containing a 5-position electron withdrawing ring substituent adsorbed to the {100} crystal faces of the grains being grown.
摘要:
A method of purifying an antifreeze protein (AFP) and methods of producing AFPs are disclosed. The method of purifying an AFP includes heating a crude AFP in an aqueous medium to a temperature and for a length of time sufficient to precipitate at least some thermally unstable proteins in the crude AFP and form a precipitate and a supernatant; and removing the precipitate from the supernatant. One method of producing an AFP includes collecting a crude source of the AFP; and purifying the AFP by the purification method. Another method of producing an AFP includes growing or culturing a host configured to express a recombinant AFP in a growth medium, and collecting a crude AFP from the host and/or the growth medium. The growth medium comprises water, a protein hydrolysate or other source of amino acids, a yeast extract, a biologically metabolizable C3-C6 polyol, and one or more phosphate salts.
