OBJECTIVE To investigate the in vitro effects of the antibacterial drugs, meropenem trihydrate, piperacillin sodium, and cefoperazone sodium, on the activity of human serum paraoxonase (hPON1). METHODS hPON1 was purified from human serum using simple chromatographic methods, including DEAE-Sephadex anion exchange and Sephadex G-200 gel filtration chromatography. RESULTS The three antibacter...

The mixing of two histoincompatible human lymphocyte cell lines generated the release of a soluble factor which was capable of nonspecifically enhancing the in vitro immune response of normal mouse spleen cells against sheep erythrocytes. When active supernates were subjected to exclusion chromatography on Sephadex G-150 and BioGel P-150, the active principle eluted with molecules of approximat...

Studies were carried out to natural papain inhibitor from papaya latex. Fresh latex from green fruits of Carica papaya was collected and immediately transported in ice bath to the lab, from which three fractions with inhibitor effect of esterase papain activity were isolated by latex dialysis, Sephadex G-25 gel filtration and ionic exchange chromatography in SP-Sephadex C-25. The isolated fract...

Initial extracts from etiolated plants contained two aggregates of phytochrome. A major fraction was almost excluded by Sephadex G-200 and was within the fractionation range of Sepharose 4 B. A minor fraction was within the fractionation range of Sephadex G-200. Modifications of a previous isolation procedure which allowed retention of this aggregation state are reported. With respect to gel fi...

Lethal and hemolytic toxins were purified by acetone precipitation, Sephadex G-50, CM-cellulose and CM-Sephadex column chromatography from the tentacles and bodies of the sea anemone Actinia equina. The isolated toxins, with a mol. wt of 19,000 determined by SDS-polyacrylamide gel electrophoresis, differed only slightly in amino acid composition and had a high tryptophan content. The isoelectri...

We have compared two methods for separating the isoenzymes of creatine kinase in serum and measuring their activity: chromatography on diethylaminoethyl-Sephadex A-50, with both continuous and discontinuous gradient elution, and electrophoresis on cellulose acetate. Results by continuous and discontinuous gradient elution correlated well both for tissue extracts and sera. Electrophoresis on cel...

Kedarcidin, a new chromoprotein antitumor antibiotic, was isolated from the culture broth of a novel actinomycete strain L585-6 (ATCC 53650). The antibiotic was recovered from the culture filtrate by adsorption to QAE ion exchanger and purified by successive application of gel filtration and ion exchange chromatography with Sephadex G-50 and DEAE-Sephadex, respectively. Kedarcidin is an acidic ...

This paper deals with a comparative aspect of the fibrinolytic system in man and rabbit, particularly relating to the "proactivator-like component" in rabbit plasma whose behavior is similar to proactivator A of human plasma fractionated by gel filtration and apparently acts as proactivator in the presence of a small amount of human globulin. The entity of this component has been remained yet q...

Recently we reported that removal of noncovalently bonded protein from glutenin resulted in decreased viscoelasticity. In that study, two glutenin fractions were isolated by successive gel filtration of glutenin on Sephadex G-200 in the solvents acetic acid-guanidine hydrochloride (GuHCl)-cetyltrimethylammonium bromide (AGC) and sodium dodecyl sulfate (SDS). This note reports the S20,W values o...
