Effects of ammonia and lactate on hybridoma growth, metabolism, and antibody production
(Wiley Subscription Services, Inc., A Wiley Company, 1992-02-20)
The influence of ammonia and lactate on cell growth, metabolic, and antibody production rates was investigated for murine hybridoma cell line 163.4G5.3 during batch culture. The specific growth rate was reduced by one-half ...
Neural retina-specific leucine zipper gene NRL (D14S46E) maps to human chromosome 14q11.1-q11.2
(Elsevier, 1992-10)
The product of a neural retina-specific gene, NRL, belongs to the "leucine zipper" family of DNA-binding proteins and has a strong similarity to the v-maf oncogene product. The NRL gene maps to human chromosome 14 by ...
Vibrational spectroscopic studies of -alternating valine peptides
(Elsevier, 1992-04-24)
Raman and infrared spectra of Boc-(Val--Val)n-OMe [(-Val)n], with n = 4, 6 and 8, were obtained in crystalline and solution states. Based on predictions from normal-mode calculations of a number of relevant single- and ...
Synthesis and characterization of molybdenum nitride hydrodenitrogenation catalysts
(Elsevier, 1992-06-30)
Details concerning the relationships between the structural, chemical and catalytic properties of Mo nitrides have been elucidated. A series of Mo nitride catalysts were prepared by the temperature programmed reaction of ...
Synthesis and characterization of 7-nitrobenzo-2-oxa-1,3-diazole (NBD)-labeled fluorescent opioids
(Elsevier, 1992-01-22)
Alkylation of sarcosine with 4-chloro-nitrobenzo-2-oxa-1,3-diazole (NBD-chloride) furnished a fluorescent tag that was coupled with a tetrahydrothebaine derivative and [beta]-naltrexamine, respectively, to yield the ...
Normal-mode analysis of infrared and Raman spectra of poly(vinyl fluoride)
(Elsevier, 1992-03-02)
Infrared and Raman spectra of samples of poly(vinyl fluoride) (PVF) have been recorded. The vibrational spectra have been analyzed by means of normal-mode calculations. A force field was derived by using 2-fluorobutane as ...
New mannose-specific lectins from garlic (Allium sativum) and ramsons (Allium ursinum) bulbs
(Elsevier, 1992-05-22)
Two new mannose-binding lectins were isolated from garlic (Allium sativum, ASA) and ramsons (Allium ursinum, AUA) bulbs, of the family Alliaceae, by affinity chromatography on immobilized mannose. The carbohydrate-binding ...
Interaction between bacteriophage [lambda] and its Escherichia coli host
(Elsevier, 1992)
Bacteriophage [lambda] relies to a large extent on processes requiring interactions between viral- and host-encoded proteins for its lytic growth, establishment of lysogeny, and release from the prophage state. Both ...
Preparation and Reactivity of Polyfunctional Zinc and Copper Organometallics Bearing Sulfur Functionalities
(Elsevier, 1992)
Iodomethylthiobenzoate 5 and [alpha]-chloroalkyl phenyl sulfides 6 were found to insert zinc dust in THF under very mild conditions (10-25 [deg]C, 0.5-2 h) leading to zinc [alpha]-thioorganometallics. After a transmetallation ...
