Bioactivities Of A Tumour Necrosis Like Factor Released By Chicken Rnacrophages, Silke Rautenschlein, Anuradha Subramanian, Jagdev M. Sharma
Bioactivities Of A Tumour Necrosis Like Factor Released By Chicken Rnacrophages, Silke Rautenschlein, Anuradha Subramanian, Jagdev M. Sharma
Papers in Biotechnology
To test for tumour necrosis-like factor (TNF) of chickens, supernatants of a lipopolysaccharide (LPS)-stimulated chicken macrophage cell line MQ-NCSU were analysed. A sequence of ion-exchange and gel-permeation chromatography was utilised to isolate TNF-like activity from the culture supernatant. The peak of TNF-like cytotoxic activity corresponded to the fractions with a nlolecular weight of 81 kDa or higher. Polyclonal anti-human TNF-a antiserum cross-reacted by Western blotting with a 17 kDa protein in the TNF-containing fraction ~ ~ n d e denaturing conditions. This result indicated that chicken TNF-like factor in the biologically active form may be a protein multimer of monomers …

In a previous article,1 the development and molecular characterization of three polyesters from N-carbobenzyloxy-L-glutamic acid (ZGluOH) were reported. The polymers were a linear, heterochain polyester (ZGluOH and ethylene glycol), a crosslinked heterochain polyester (ZGluOH and diglycidyl ether of 1,4-butanediol), and a crosslinked, heterochain aromatic polyester (ZGluOH and diglycidyl ether of bisphenol A). In this manuscript, results of biodegradation studies are reported. The three polymers hydrolyzed to low molecular weight oligomers similar to the monomers with lipase. When exposed to a mixed culture of micro-organisms, the first two resins degraded to biomass and respiratory gases. The crosslinked heterochain aromatic polyester resisted …

A Mutant Of Chlamydomonas Reinhardtii With Reduced Rate Of Photorespiration, Kensaku Suzuki, Tarlan G. Mamedov, Toraoyoshi Ikawa

Photorespiration rates under air-equilibrated conditions (0.04% CO2 and 21% O2) were measured in Chlamydomonas reinhardtii wild-type 2137, a phosphoglycolate- phosphatase-deficient (pgpl) mutant and a suppressor double mutant (7FR2N) derived from the pgpl mutant. In both cells grown under 5% CO2 and adapted air for 24 h in the suppressor double mutant, the maximal rate of photorespiration (phosphoglycolate synthesis) was only about half of that in either the wild type or the pgpl mutant (18-7F) cells. In the progeny, the reduced rate of photorespiration was accompanied by increased photosynthetic affinity for inorganic carbon and the capacity for growth under air whether …

The present study was carried out to 1) evaluate the viability of in vitro fertilized zygotes after microinjection of DNA, 2) assess the influence of oocyte quality upon the development rate of embryos when injected with DNA, and 3) determine the integration frequency of green fluorescent protein DNA into microinjected embryos. Oocytes were aspirated from ovaries of nine nonlactating Holsteins and were categorized into grades A, B, C, and D. At 16 h after in vitro fertilization, approximately half of the pronuclear stage presumptive zygotes were classified as having 1 pronucleus or 2 pronuclei, and they were microinjected with DNA …
A Red-Dot-Blot Protein Assay Technique In The Low Nanogram Range, Tiilin Marcol, Anuradha Subramanian
A Red-Dot-Blot Protein Assay Technique In The Low Nanogram Range, Tiilin Marcol, Anuradha Subramanian
Papers in Biotechnology
A simple, sensitive, rapid (3 min), and highly reproducible solid-phase assay for the detection of proteins in the low nanogram range (4 ng) is described. The assay is based on differential Pon-ceau S staining of the protein spots on nitrocellulose and quantification of the protein- dye com-plexes on lubricated membranes using a densitometer. The dye solution used for protein stain-ing contained 0.1% Ponceau S in 15% phosphoric acid and 10% ethanol. Proteins were directly spotted onto pre- Ponceau S-stained nitrocellulose membranes, crosslinked with glutaraldehyde, rinsed in NaOH, restained with Ponceau S, and finished by rinsing in acid water at pH …
