objective(s): streptokinase (ska) is an antigenic protein which is secreted by streptococcus pyogenes. streptokinase induces inflammation by complement activation, which may play a role in post infectious diseases. in the present study, recombinant streptokinase from s. pyogenes was produced and showed that recombinant ska protein was recognized by infected human sera using western blot analysi...

lack of prostate specificity and intercellular localiza-tion of its gene product make this gene a poor serum biomarker. FN1 (fibronectin 1) and VEGF (vascular endo-thelial growth factor) are associated with prostate cancer and encode secreted proteins; however, these genes lack prostate-specific tissue specificity (15–18). The lack of prostate tissue specificity in the expression of these 2 gen...

As a production platform for recombinant proteins, plant leaf tissue has many advantages, but commercialization of this technology has been hindered by high recovery and purification costs. Vacuum infiltration-centrifugation (VI-C) is a technique to obtain extracellularly-targeted products from the apoplast wash fluid (AWF). Because of its selective recovery of secreted proteins without homogen...

objective(s): the aim of this study was to synthesize triangular gold nanoparticles, and then to evaluate their capability for inhibition of candida albicans secreted aspartyl proteinase 2(sap2).materials and methods: to synthesize the nanoparticles, hydrogen tetrachloroaurate and hexadecyl trimethyl ammonium bromide were incubated in presence of sn(iv) meso-tetra(n-methyl-4-pyridyl) porphine t...

The composition and functions of the secreted proteome are controlled by the life spans of different proteins. However, unlike intracellular protein fate, intrinsic factors determining secreted protein aging and turnover have not been identified and characterized. Almost all secreted proteins are posttranslationally modified with the covalent attachment of N-glycans. We have discovered an intri...
