Useful buffer and gel systems for polyacrylamide gel electrophoresis.
Seven buffer and gel systems for polyacrylamide gel electrophoresis using discontinuous voltage and pH gradients (disc electrophoresis according to ORNSTEIN-UAVIS) and five systems using discontinuous voltage gradients at constant pH (according to ALLEN) have been compiled and characterized. Usefulness and applicability of the systems for clinical investigations are discussed and illustrated by...
متن کاملinvestigation of single-user and multi-user detection methods in mc-cdma systems and comparison of their performances
در این پایان نامه به بررسی روش های آشکارسازی در سیستم های mc-cdma می پردازیم. با توجه به ماهیت آشکارسازی در این سیستم ها، تکنیک های آشکارسازی را می توان به دو دسته ی اصلی تقسیم نمود: آشکارسازی سیگنال ارسالی یک کاربر مطلوب بدون در نظر گرفتن اطلاعاتی در مورد سایر کاربران تداخل کننده که از آن ها به عنوان آشکارساز های تک کاربره یاد می شود و همچنین آشکارسازی سیگنال ارسالی همه ی کاربران فعال موجود در...
Characterization of canine mycoplasmas by polyacrylamide gel electrophoresis and immunodiffusion.
Canine mycoplasmas which had been characterized by biological and serological methods were further studied by using polyacrylamide gel electrophoresis (PGE) and double diffusion in agar gel. The three dog mycoplasmas previously characterized, Mycoplasma canis, M. maculosum, and M. spumans showed distinctive patterns by PGE. Five additional representative isolates from dogs had been characterize...
متن کاملMammalian melanosomal proteins: characterization by polyacrylamide gel electrophoresis.
For many years the major problem impeding the elucidation of the structure of melanin and the melanosome has been the insolubility of the melanin polymer. To date, alkaline and acid hydrolysis seem to be the only methods available which can completely solubilize the melanosome (1); unfortunately, both methods degrade the constituents of the organelle other than the melanin polymer. The recent e...
متن کاملPolyacrylamide Gel Electrophoresis
Polyacrylamide gels are typically formed by polymerization of the monomer acrylamide crosslinked to the co-monomer, N,N’-methylenebis-acrylamide, commonly called BIS. This process is a freeradical polymerization that requires an initiator, usually ammonium persulfate, and a catalyst like N,N,N’,N’-tetraethylmethylenediamine (TEMED). A distinct advantage of polyacrylamide gel systems is that by ...
