The response of strain 2 guinea pigs to limiting doses of bovine serum albumin is under dominant genetic control linked with the poly-L-lysine gene. Inbred strains 2 and 13 guinea pigs make similar antibody responses to 10 mug bovine serum albumin, whereas strain 2 but not strain 13 animals produce significant amounts of antibodies in response to 0.1 mug. The relationship between the presence o...

Spinach chloroplasts were immobilized with vinyl monomers by radiation-induced polymerization at low temperature and stored in buffer containing bovine serum albumin. The lifetime of O(2) evolution activity in photosystem II was prolonged remarkably in immobilized chloroplasts. Thermostability of immobilized chloroplasts stored in buffer containing bovine serum albumin was far better than that ...

Background: Cell therapy and cell culture have received much attention in recent decades. Suitable cell growth requires growth supplements such as fetal bovine serum (FBS). FBS is component rich in nutrients, growth factors and supplementary compounds. However, FBS utilization has some limitations including mass production. Therefore, finding alternatives with the same growth promoting effects ...

PURPOSE Recently it has been shown that the transport as well as clearance of retinol from isolated rod photoreceptors requires an extracellular factor. Interphotoreceptor retinoid-binding protein (IRBP) is a component of the interphotoreceptor matrix (IPM) and is known to bind visual cycle retinoids. Serum albumin and serum retinol-binding protein (sRBP), proteins capable of binding retinoids,...

Enrichment of cell suspension with germ cells prior to injection into recipient seminiferous tubules is of importance in spermatogonial stem cells (SSCs) transplantation. Knock-out serum replacement (KSR) has been reported to enhance the proliferation of murine SSCs and human embryonic stem cells. The aim of the present study was to investigate the effect of KSR versus fetal bovine serum (FBS) ...

Glycophorin both in solution and inserted into liposomes blocks invasion of erythrocytes by the malaria parasite Plasmodium falciparum. Furthermore, one sugar, N-acetyl-D-glucosamine (GlcNAc), completely blocks invasion of the erythrocyte by this parasite. GlcNAc coupled to bovine serum albumin to prevent the sugar entering infected erythrocytes was at least 100,000 times more effective than Gl...

Light scattering measurements have been made on solutions of hyaluronic acid in the presence and absence of bovine serum albumin. The results are interpreted as showing an exclusion of bovine serum albumin from molecules of hyaluranic acid, the magnitude of which agrees with most other measurements of exclusion. The theory of the effect of heterogeneity of exclusion is given. The apparent heter...

Bovine herpesvirus (infectious bovine rhinotracheitis virus)-infected cell antigens were solubilized with Nonidet P-40. The crude antigen extract was separated by reaction with bovine hyperimmune serum in line immunoelectrophoresis; individual immunoprecipitates were used to immunize rabbits. Rabbit sera possessing serum neutralizing activity were analyzed by reaction with crude antigen extract...

Semiconductor nanoparticles (quantum dots) are promising fluorescent markers, but it is very little known about interaction of quantum dots with biological molecules. In this study, interaction of CdTe quantum dots coated with thioglycolic acid (TGA) with bovine serum albumin was investigated. Steady state spectroscopy, atomic force microscopy, electron microscopy and dynamic light scattering m...
