    Details
    ISSN: 1573-0778
    Keywords: codeine ; ELISA ; monoclonal antibody ; opium alkaloid ; qualitative analysis ; thebaine
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine , Process Engineering, Biotechnology, Nutrition Technology
    Notes: Abstract The ratio of hapten and bovine serum albumin in antigen conjugate was exactly determined by matrix-assisted laser desorption/ionization mass spectrometry. Monoclonal antibodies against thebaine and codeine were produced by hybridoma fused with the sprenocytes immunized with thebaine- and codeine-bovine serum albumin conjugate and HAT-sensitive mouse myeloma cell line, P3-X63-Ag8-653. No cross-reaction of anti-thebaine antibody against morphine was observed. Very small cross-reaction appeared in codeine (0.004%). The cross-reaction of anti-codeine antibody against morphine and thebaine was 2.97 and 5.98%, respectively. The full measuring range of the assay extends from 60 pg mL to 1 ng mL for thebaine and 1 ng mL to 100 ng mL for codeine.

    CHO cell growth and recombinant interferon-γ production: Effects of BSA, Pluronic and lipids (1995)
    Springer
    Cytotechnology 19 (1995), S. 27-36 
    Details
    ISSN: 1573-0778
    Keywords: BSA ; CHO cells ; interferon-γ ; linoleic acid ; lipids ; Pluronic F68
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine , Process Engineering, Biotechnology, Nutrition Technology
    Notes: Abstract The role of bovine serum albumin in mammalian cell cultures and the possibility of its substitution by other components in a serum-free medium has been investigated. In this study, BSA was shown to be important for growth and product formation in CHO cells expressing recombinant human interferon-γ. There were indications that its stimulating growth effect was dependent on the source of BSA used and probably was related to the purification procedure used for the production of the desired albumin fraction. Cell growth did not occur in the absence of BSA but at low concentration (1 mg ml−1) it was stimulated by the addition of a combination of a commercial lipid mixture plus Pluronic F68. However, under the latter conditions IFN-γ production was adversely effected. The importance of individual lipid components was investigated using a statistical approach based on a Plackett-Burman design. Linoleic acid was identified as a positive variable for cell growth while cholesterol was identified as a negative variable for both cell growth and IFN-γ production. When a combination of linoleic acid plus Pluronic F68 was included in the formulation of low BSA medium, cell growth was similar to that at high BSA concentration (5 mg ml−1) but the IFN-γ concentration was significantly reduced (ca. 45%).

    High density culture of mouse-human hybridoma cells using a perfusion culture apparatus with multi-settling zones to separate cells from the culture medium (1989)
    Springer
    Cytotechnology 2 (1989), S. 5-8 
    Details
    ISSN: 1573-0778
    Keywords: hybridoma ; monoclonal antibody ; perfusion culture ; mammalian cell culture ; serum-free culture

    Notes: Abstract Mouse-human hybridoma X87X cells were cultivated using a novel perfusion culture apparatus provided with three-settling zones to separate the cells from the culture medium by gravitational settling. The maximum viable cell density in a serum-free culture medium attained 3.0×107 cells/ml, when the specific perfusion rate was set to 2.3 vol day-1, and monoclonal antibody was continuously produced. These results were almost the same as those in the perfusion culture vessel with one settling zone and revealed that the process with a plurality of settling zones is a promising one for scale-up of a gravitation type of perfusion culture vessel.

    SSGF-I, a potent growth-promoting substance for mammalian cells from swine serum (1989)
    Springer
    Cytotechnology 2 (1989), S. 9-17 
    Details
    ISSN: 1573-0778
    Keywords: heterohybridoma ; LDL ; monoclonal antibody ; serum-free medium ; PEG ; swine serum
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine , Process Engineering, Biotechnology, Nutrition Technology
    Notes: Abstract A small amount of swine serum markedly stimulated cell growth for high productivity subclones derived from a mouse human-human heterohybridoma, N12-16.63, secreting an anti-tetanus toxoid human monoclonal antibody in a polyethylene glycol (PEG)-containing serum-free medium, PEG-86-1. A growth promoting substance, SSGF-I, was isolated from the serum by ammonium sulfate fractionation, Cibacron blue F3A-G affinity chromatography, DEAE-agarose ion exchange chromatography, and gel filtrations on Trisacryl GF 2000 and Sephacryl S-300. SSGF-I was characterized as a low density lipoprotein (LDL) of swine serum by its physico-chemical properties. It promoted cell growth synergistically with PEG and its optimum concentration was 1 to 100μg/ml. Human LDL was less active, and human or swine high density lipoprotein (HDL) and very low density lipoprotein (VLDL) were inactive. Based on these results, we propose an improved serum-free medium, PEG-86-3, which contains all the ingredients of PEG-86-1 and 10μg/ml SSGF-I. This medium is useful for not only high productivity heterohybridomas but also for a variety of lymphoid cell lines.

    A serum-free medium for hybridoma cell culture (1993)

    Notes: Abstract The effects of several different substances, including insulin, transferrin, ethanolamine, selenite and butyrate on the growth of murine hybridoma 2F7 cells, which secrete monoclonal antibody against small cell lung cancer, were investigated, and a serum-free medium SFMI was formulated. The effects of taurine, spermidine, progesterone and adenine on the cell growth were tested further on the basis of the medium SFMI, and a modified serum-free medium SFM II was established. On the basis of medium SFM II, the substitution tests of ferric citrate for transferrin were carried out, and it was found that transferrin could be replaced. The experiments suggested that the formulated serum-free medium was suitable for 2F7 cell growth and monoclonal antibody secretion, and thus facilitated subsequent purification of monoclonal antibody.
