Abstract:

The chiral separation of etoxazole enantiomers on Lux Cellulose-1, Lux Cellulose-3, Chiralpak IC, and Chiralpak AD chiral columns was carefully investigated by normal-phase high performance liquid chromatography and reverse-phase high performance liquid chromatography (HPLC). Hexane/isopropanol, hexane/n-butanol, methanol/water, and acetonitrile/water were used as mobile phase at a flow rate of 0.8 mL/min. The effects of chiral stationary phase, mobile phase component, mobile phase ratio, and temperature on etoxazole separation were also studied. Etoxazole enantiomers were baseline separated o

Abstract:

The retention behavior of a wide variety of stationary phases was compared in supercritical fluid chromatography (SFC) and normal-phase high-performance liquid chromatography (NP-HPLC). We also attempted to elucidate the retention behavior in SFC by investigating the selectivity of the different stationary phases. SFC separation conditions with polar stationary phases, such as silica gel (SL) and diol (Diol) phases, operate via adsorptions that include hydrophilic and ionic interactions similar to those in NP-HPLC. Moreover, non-polar stationary phases, such as pentabromophenyl (PBr), pyrenyle

PS is bound to one (C4bp) and possibly two (protein S binding protein) other proteins in plasma, necessitating the validation of any assay, both by standard criteria and for its ability to measure the different forms of PS in plasma. Murine monoclonal antibody PS-2a was adsorbed to solid phase microtiter plate wells at 10 ug/ml, pH 9.6. For the assay, affinity purified PS standard, free of C4bp, or plasma samples were incubated with 125 I labelled PS.Serial dilutions of pooled normal plasma paralleled the standard curve.

Abstract:

A new congential dysfibrinogenemia, denoted as Milano III, was found in a 13-year-old girl with recurrent thrombophlebitis. Plasma of the patient exhibited prolonged thrombin and reptilase times. Plasma fibrinogen concentration, determined by a functional assay, was less than 0.2 g/1 while the immunological method revealed normal fibrinogen levels. Fibrinopeptide release, induced by thrombin, was normal whereas polymerization of fibrin monomers was delayed. Under conventional conditions for normal fibrin aggregation, with and without added calcium, the final turbidity of abnormal fibrin was lé

Gel filtration experiments demonstrated that the peptide was not physically associated with the enzyme. A 15 amino acid peptide with the COOH-terminal sequence of the acti

Abstract:

A hitherto unidentified amino acid substitution of γ Arg-275 by Cys has been found in two abnormal fibrinogens, Osaka II and Morioka. The propositi are both asymptomatic heterozygotes for the abnormality characterized by altered polymerization of fibrin monomers. Reducing SDS-PAGE revealed that fibrinogens derived from thé propositi both consist of two populations; one with a normal and the other with an abnormal longer γ-chain by 0.5 Kd.The γ-γ cross-linking took place nearly normally, however. Analyzing plasmic digests of fibrinogen by SDS-PAGE, we located the abnormality residing in the γ-c

Abstract:

Prothrombin Madrid, a mutant prothrombin, was detected in a patient with a excessive bleeding history. The defect was characterized by a low coagulant activity contrasting with a normal level of prothrombin antigen in plasma. Activation of the purified protein was impaired by the absence of one of the two factor Xa catalyzed cleavages, generating meizothrombin which expressed a thrombin-like activity but was inactive on fibrinogen (Guillin et al., Ann. N.Y. Acad. Sci. 370:414, 1981). Prothrombin and prothrombin Madrid were isolated directly from plasma, with high yield, by immunoaffinity chrom

Abstract:

Platelet (plt) factor 4 (PF4) is an alpha granule protein which can modulate T lymphocyte function. T cells may help regulate megakaryocytopoiesis. Therefore, we hypothesized that T cell-PF4 interactions might play a role in autoregulating marrow megakaryocyte (MEG) production. To test this idea, we studied MEG colony formation in plasma clot cultures containing human serum derived solely from pit poor normal AB plasma, enriched hematopoietic progenitor cells (HPC), autologous T cells, and exogenous PF4. Highly purified PF4 (single band on SDS gel) was prepared from outdated human pits by a co
