Single-molecule tracking reveals the protein bovine serum albumin exhibits anomalous kinetics with a heavy-tailed dwell time distribution on PEG surfaces. This effect is shown to be caused by the ability of the protein to oligomerize in solution.

We investigated the influence of THz laser radiation of frequencies of 1.15 THz and 3.68 THz and radiation power of about 10 Mw on protein (bovine serum albumin). Using UV spectrophotometry, we revealed increase in the optical density of irradiated samples of bovine serum albumin at the characteristic absorption bands, which is evidence of conformation changes in protein molecules

 Dalam pengembangan metoda analisis residu antibiotik pada produk pangan hewani secara immunokimia telah dilakukan sintesis imunogen kloramfenikol (CAP) dengan protein Bovine Serum Albumin (BSA) dan Keyhole Limpet Hemocyanin (KLH) dengan metoda konjugasi mixed anhidrad. Hasil sintesis digunakan untuk produksi antibodi.Antigen dan antibodi yang dihasilkan dijadikan prangkat analisis residu antibiotik dengan Competitive Enzyme Linked Immunosorbent Assay (ELISA kompetitif). Hasil penelitian menunjukkan bahwa metoda konjugasi mixed anhidrad pada preparasi imunogen dengan jumlah CAP yang terkonjugasi ke grup amino bebas dari molekul protein BSA (CAP-BSA) adalah 18 unit dan ke protein KLH (CAP-KLH) adalah 782 unit. Antibodi poliklonal CAP-BSA dan CAP-KLH yang diproduksi dengan rata-rata kandungan IgG CAP-BSA 2,07 mg/ml dan IgG CAP-KLH 2,21 mg/ml.

Protein Bovine Serum Albumin

Several glycolytic enzymes (lactate dehydrogenase, pyruvate kinase, glyceraldehyde-3-phosphate dehydrogenase) were radiolabelled by [125I]iodination, conjugation with 125I-labelled Bolton & Hunter reagent and reductive [3H]methylation, and their degradative rates after microinjection into 3T3-L1 cells compared with that of the extracellular protein bovine serum albumin. Although the albumin remains largely cytosolic in recipient cells, the glycolytic enzymes rapidly (less than 30 min) become insoluble, as measured by detergent and salt extractions. The microinjected glycolytic enzymes appear to form disulphide-linked aggregates, are found in a cell fraction rich in vimentin-containing intermediate filaments and histones (nuclear-intermediate-filament fraction), and are degraded slowly by a lysosomal mechanism, as judged by the effects of inhibitors (NH4Cl, leupeptin, 3-methyladenine). 125I-labelled bovine serum albumin appears to be degraded rapidly and non-lysosomally. Prolonged treatment (96 h) of cultured cells with leupeptin results in the accumulation of pulse-labelled ([35S]methionine for 24 h) endogenous cell proteins in the detergent-and salt-non-extractable residue, but NH4Cl and 3-methyladenine do not have this effect. The findings are in terms of the interpretation of experiments involving microinjection of proteins to study intracellular protein protein degradation by autophagy.
