validation of radiation sterilization dose for proteases

Production and Purification of Recombinant Proteins

No yearly validation costs for cleaning and sterilization are needed anymore when single-use systems are used A disadvantage of the single-use system is that the operational expenses will increase storage location for single-use bags and tubing will increase and the dependence of the company to one supplier of single-use systems will increase

PharmaTutor has been created with the aim to create an interactive platform which could provide unprecedented support to novice pharmacy students and researchers in their day to day doubts and also to increase the awareness among the students about this field and introduce the various upcoming areas of research and Job opportunities

A comparison of the transcriptome of Drosophila

Results We studied effects of ionizing radiation (144 360 and 864 Gy) entomopathogenic fungus (10 and 100 CFU) starvation (16 h) and cold shock (+4 0 and -4C) on an organism's viability indicators (survival and locomotor activity) and transcriptome changes in the Drosophila melanogaster model All stress factors but cold shock resulted in a decrease of lifespan proportional to the dose

Both radiation types at the dose of 25 kGy damaged the elastic and collagen fibers in the xenograft dermis at the dose of 25 kGy of both radiation type and elastic and collagen fibers Almost all of the data obtained from relevant researches and clinical based studies proved and confirmed the safe and effective dose of gamma irradiation at 15 kGy and 25 kGy for CAM and LAM respectively

Dielectric Barrier Discharge (DBD) Surface Plasma

Thus far based on all the literature published on this subject it seems that the only clear consensus on the role of UV radiation in plasma sterilization is that different pressure regimes lead to the emission of differe nt ranges of UV radiation which in turn might influence the process of plasma sterilization Reactive Chemical Species: Among the primary products of electron collision are

Introduction to sterilization: definitions and challenges

Sterilization validation studies must document that the product attains the required SAL after exposure to the proposed process In the industry sterilization validation is generally evaluated by first determining the qualitative and quantitative bioburden (the type and number of viable microorganisms present on the device just prior to sterilization) after the manufacturing process then
