Spleen Starch

Cathepsin D (from bovine spleen) [9025-26-7] Mr 56,000, [EC 3.4.23.5]. Purified on a CM column after ammonium sulfate fractionation and dialysis, then starch-gel electrophoresis and by ullracentrifugal analysis. Finally chromatographed on a DEAE column [Press et al. Biochem J 74 501 I960],... 

Starch-gel migration of bone alkaline phosphatase yields bands in locations that can be occupied by gastrointestinal juice alkaline phosphatase as well as by the enzyme of kidney, lung, and spleen. High heat sensitivity is a property of the alkaline phosphatase from these various sources. Hence findings based on starch-gel electrophoresis and heat sensitivity in themselves are not diagnostic of a bone source.

Nucleotidase isozymes detected with various substrates after starch gel electrophoresis of homogenates from mouse tissues testis (T), liver (L), kidney (K), heart (H), brain (B), spleen (S) and skeletal muscle (M). 

However, when administered into the body, the particulate carriers are inevitably exposed to an attack firom the immune system, which protects the body from invasion by foreign products. Thus, injected particles are removed from blood via recognition by phagocytic cells [essentially macrophages located in the mononuclear phagocyte system (MPS), mainly in the liver and spleen]. For example, 50-90% of polystyrene latex particles disappear firom blood within the first five minutes after injection (Ilium et al, 1987). The same fate is observed in the case of particles made of other materials, such as poly(lactic acid) (PLA) (Bazile et al, 1992), polycyanoacrylate (Kreuter et al, 1979), polyacryl starch (Laakso et al, 1986), or albumin (Gottlieb ei a/., 1990). 

In another investigation (Neelin and Butler, 1961) specificity and a high degree of heterogeneity of histones were also discovered in the organs of the chicken. Histones of the spleen and liver, when tested by zonal electrophoresis on starch gel, formed 18 zones, the arrangement of which varied. Histones of the erythrocytes, however, possessed a much smaller assortment of components.
