Purification and characterization of lipid transfer protein(s) from human lipoprotein-deficient plasma.
Lipid transfer activities from human plasma have been characterized to determine whether triglyceride and cholesteryl ester transfer proteins are identical. After sequential purification by phenyl-Sepharose, CM-cellulose, chromatofocusing, and gel filtration, both triglyceride and cholesteryl ester transfer activities were purified approximately 15,000-fold compared to lipoprotein-deficient pla...
متن کاملRapid purification of human plasma lipid transfer proteins.
Lipid transfer protein (LTP) was isolated from human plasma after lipoproteins were removed by precipitation with dextran sulfate. Three sequential chromatogrpahic procedures were used: butyl-Toyopearl 650, CM-Toyopearl 650, and Toyopearl HW-55. The entire procedure required only a few days and purification was as high as 43,000-fold from the lipoprotein-depleted plasma with the yield of 30%. T...
متن کاملCharacterisation of protein microheterogeneity and protein complexes using on-chip immunoaffinity purification-mass spectrometry.
Post-translational modification of proteins may influence their interactions with other plasma proteins, as well as having an effect on many aspects of the metabolism of the protein, such as receptor binding, tissue uptake, degradation and excretion. Many post-translational modifications occur in a physiological context, while others are specific for certain diseases, which is why they are of d...
متن کاملpurification of lipid transfer protein 2 (ltp2) from iranian rice paddy
abstract plant nonspecific lipid transfer proteins (nsltps) are divided into nsltp1 and nsltp2. the existence of an internal hydrophobic cavity, is a typical characteristic of nsltps that serves as the binding site for lipid substrates. in this communication a simple, rapid and low-cost alternative method was developed for purification of nsltp2 from rice paddy. after extracting, final supernat...
متن کاملکلون کردن ژن ns-ltp (non-specific lipid-transfer protein) برنج با برچسب gst به داخل باکتری اشرشیا کلی
پروتئین های ناقل لیپید (ltps) گروهی از پروتئین ها با وزن ملکولی متوسط در نزد گیاهان هستند که دارای پتانسیل های کاربردی به ویژه در سیستم های رها سازی دارو می باشند. هدف از این تحقیق، کلون کردن ژن ltp2 مربوط به گیاه برنج(oryza sativa) در وکتور بیانی pgex-6p-2، در باکتری e.coli (top10) جهت تولید پروتئین به صورت متصل با gst می باشد. از آنجائیکه ژن ltp2 در گیاه برنج را فاقد اینترون است این ژن با کمک...
