1. The polychaete worm Marphysa sanguinea has a circulating erythrocruorin of mol.wt. about 2.4x10(6) (S(0) (20,w) 58.2s, D(20,w) 2.06x10(-7) cm.(2)/sec). This is the predominant form existing at pH 6-8 and (non-protein) I 0.10-0.21, and also at approx. pH 6.7 and I 0.15-3.00. 2. The pigment contains 2.24% of protohaem. 3. The 58s protein has an… (More)
From the coagulocytes (amoebocytes) coagulogen (fibrinogen) was isolated, and purified on Sephacryl S-200. The cell homogenate contained one major protein species with a minimum molecular weight of 70,000. This protein clotted in the presence of human thrombin, human factor XIII and Ca++. The coagulogen contained no free thiol groups, however these were… (More)
A rapid automated method for the estimation of factor Xa was developed using the "Centrifichem' rotary fast analyser and the substrate S-2222. The problem of interference from fibrin was overcome by performing the activation of factor X during centrifugation, so that defibrination and activation were achieved in a single step. A range of factor Xa… (More)
A case of type III hyperlipoproteinaemia has been investigated before and after treatment, and the unusual serum lipoprotein patterns obtained by molecular exclusion or pore limit electrophoresis on acrylamide gradients have been compared.
The carnivorous Utricularia (Lentibulariaceae) is a small herb of multifarious wet habitats worldwide. Eleven of the 14 Peninsular Malaysian species range into the mountains. Distribution, disturbance adaptability and collection frequency were used to formulate their commonness category. Common (U. aurea, U. bifida, and U. minutissima) and fairly common (U.… (More)
