A simple method for identification and characterization of telomere-binding proteins is described in this article. After Sodium Dodecyl Sulphate-Polyacrylamide gel electrophoresis (SDS-PAGE), proteins are eluted, renatured and used for retardation analysis with labelled oligonucleotides corresponding to human and plant of telomeric sequences. We show here that this method is efficient to recove...

Immunological characterization of various Pseudomonas pseudomallei preparations was carried out by SDS-PAGE and Western blot using sera from infected humans and from patients with other bacterial infections. Somatic (SOM) and partially purified cell extracts (PCE) gave more complex SDS-PAGE patterns: M(r) ranged from 86 to 12.7 and 48 to 10 kDa, respectively. The culture-filtrated antigens (CF)...

One third of all genes of various organisms encode membrane proteins, emphasizing their crucial cellular role. However, due to their high hydrophobicity, membrane proteins demonstrate low solubility and a high tendency for aggregation. Indeed, conventional two-dimensional gel electrophoresis (2-DE), a powerful electrophoretic method for the separation of complex protein samples that applies iso...

Indonesia possesses tremendous marine resources. Therefore, their products are appropriate for exploration. In the prior study, bacteria generating keratinase enzyme have isolated from local fish market trash. The may hydrolyze keratin on skin. Surrounding parameters, such as temperature, pH, and incubation duration, factors affecting activity of enzyme. This study aims to isolate characterize ...

Introduction. Gallic acid is a biologically active natural compound with strong antioxidant properties. highly soluble and stable. It known to increase the thermal stability of protein. However, its bioavailability low, but interaction proteins can solve this problem. Bovine serum albumin bind various ligands, including polyphenols. The resulting complex gallic bovine become promising functiona...

Snake venoms comprise a highly complex mixture of proteins, and there is also high interspecific intraspecific variability in their composition, even the same region. Our aim was to compare composition Bothrocophias myersi, Crotalus durissus Bothrops asper, snakes from Andean region Colombia by Reverse-Phase High-Performance Liquid Chromatography (RP-HPLC). The were given research group under a...

Alkaline treatment method was used to ext ract collagen. Sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE) and circular dichroism (CD) spectra revealed that the alkali-soluble pigskin collagen (ASPC) retained the polypeptide chains and triple helix conformat ion. The amino acid profiles showed no major deviation from the characteristic collagen composition. Both of the denat...

Polyacrylamide Gel Electrophoresis (PAGE) is both an analytical and preparative tool widely used in protein analysis. Proteins are separated by PAGE in an electric field according to their size, shape and charge both in their native configuration (native PAGE) or in the presence of denaturing agents such as the ionic detergent sodium dodecyl sulfate (SDS-PAGE). A third type of electrophoretic t...

Using the technique of immune precipitation of [35S]methionine-labelled infected cell polypeptides followed by SDS-polyacrylamide gel electrophoresis and autoradiography it has been shown that SV5 and a closely related isolate are both antigenically related to human parainfluenza virus type 2. Limited cross-reactions were also demonstrated between parainfluenza virus types 1 and 3 by this metho...
