MoFe Cofactor of nitrogenase: Extraction, purification, and characterization
(Elsevier, 1989-08)
On-line multichannel Raman spectroscopic detection system for capillary zone electrophoresis
(Elsevier, 1991)
An on-line multichannel Raman spectroscopic detection system for capillary zone electrophoresis using a charge-coupled device as the detector is described. Resonant, near-resonant and non-resonant excitation Raman ...
A rapid and sensitive screening method for the detection of anti-2-acetylaminofluorene immunoglobulins
(Elsevier, 1988-04-22)
A method is described in which anti-2-acetylaminofluorene immunoglobulins may be detected using a simple and sensitive screening procedure. The method is based on immunoglobulin binding of an 125I derivatized 2-aminofluorene ...
Shape-selective separation of polycyclic aromatic hydrocarbons by reversed-phase liquid chromatography on tetraphenylporphyrin-based stationary phases
(Elsevier, 1993-07-02)
The reversed-phase chromatographic behavior of planar and non-planar polycyclic aromatic hydrocarbons (PAHs) is investigated on tetraphenylporphyrin and two metallotetraphenylporphyrin [Sn(IV), In(III)] bonded stationary ...
Activity of acyclic halogenated tubercidin analogs against human cytomegalovirus and in uninfected cells
(Elsevier, 1991-09)
Novel acyclic halogenated tubercidins (4-amino-5-halo-7-[(2-hydroxyethoxy)-methyl]pyrrolo[2,3-d]pyrimidines) were examined for their ability to inhibit human cytomegalovirus (HCMV) in yield reduction assays. 5-Bromo acyclic ...
Heterologous expression of tylosin polyketide synthase and production of a hybrid bioactive macrolide in Streptomyces venezuelae
(Springer-Verlag, 2006-02-22)
Tylosin polyketide synthase (Tyl PKS) was heterologously expressed in an engineered strain of Streptomyces venezuelae bearing a deletion of pikromycin PKS gene cluster using two compatible low-copy plasmids, each under the ...
