background aflatoxins are a group of very toxic compounds produced by a fungal species and are found in food products. aflatoxin m1 (afm1) is a type found in dairy products and resistant to pasteurization. afm1 can adversely affect hepatocytes in human and leading to various liver diseases. thus, it is essential to examine raw milk for the presence of afm1. conclusions according to the results ...
background: streptokinase is a potent activator of plasminogen to plasmin, the enzyme that can solubilize the fibrin network in blood clots. streptokinase is currently used in clinical medicine as a thrombolytic agent. it is naturally secreted by β-hemolytic streptococci. methods: to reach an efficient method of purification, an immunoaffinity chromatography method was developed that could puri...
A procedure to immunoaffinity purify the human transcription factor IIH (TFIIH) was developed using a monoclonal antibody that recognizes an epitope in ERCC3 (XPB), the largest subunit of TFIIH. The epitope recognized by the monoclonal antibody was mapped to 20 amino acids. A peptide containing the epitope was capable of displacing TFIIH from an immunoaffinity column containing the monoclonal a...
A combination of ELISA, Western blotting and immunoaffinity concentration using an anti-ginsenoside Rb1 monoclonal antibody was applied for qualitative and quantitative surveys of ginsenoside Rb1 and related ginsenosides in roots and traditional Chinese herbal medicines. To improve the low correlation between ELISA and HPLC analysis, the crude extract of roots was immunoaffinity concentrated to...
Removal of estradiol-17 beta from plasma by immunoaffinity chromatography on anti-estradiol antibodies coupled to Sepharose was investigated and compared with the use of charcoal adsorbent. Both methods completely removed added [3H]estradiol from pooled male plasma. In contrast to the adsorbent treatment, which caused marked changes in the biochemical composition of the plasma, immunoaffinity c...
We have developed a phytochrome immunoaffinity purification procedure that yields undegraded oat (Avena sativa L., cv. Garry) phytochrome of greater than 98% purity within 2 hours when starting with a brushite-purified preparation. Immunoaffinity-purified phytochrome, except for its greater purity, is indistinguishable from conventionally purified phytochrome by gel exclusion chromatography, is...
Previously, we have derived murine hybridomas producing monoclonal antibodies against DNA methyltransferase from human placenta (Kaul, S., Pfeifer, G. P., and Drahovsky, D. (1984) Eur. J. Cell Biol. 34, 330-335). One of these monoclonal antibodies, M2B10, which undergoes immune complex formation also with DNA methyltransferase from P815 mouse mastocytoma cells, was used for the immunoaffinity p...
Cooking meats produces a family of heterocylic aromatic amines that are carcinogens in rodents and genotoxic in many short-term assays. Concern that these compounds may be human carcinogens has prompted us to develop immunochemical methods for quantifying these compounds in the human diet and for identifying the parent compounds and metabolites in urine and feces. Previously reported monoclonal...
