Brain isoenzyme of creatine kinase. I. Purification of rabbit enzyme and production of specific antibodies.
Creatine kinase (EC 2.7.3.2) of rabbit brain (BB) was purified to hemogeneity as judged by sedimentation velocity analysis in the ultracentrifuge. Nevertheless, the purified enzyme contained as many as seven extraneous protein species when examined by disc electrophoresis in polyacrylamide gel. The purified preparation also showed antigenic heterogeneity when it reacted in agar gel double immun...
متن کاملMeasurement of brain-specific creatine kinase isoenzyme activity in serum.
We have modified the columti-chromatographic technique of Mercer (1) to produce a sensitive and rapid separation of serum CK2 and CK3, even at normal total serum CK activity (3).12 However, CKj was not separated from CK2. Here, we report a modification of our method such that all three CK isoenzymes are separated by stepwise elution from a mini-column of diethylaminoethyl-cellulose. CK1 has onl...
متن کاملProduction of Erythropoietin-specific polyclonal Antibodies
Background: Erythropoietin, as a principal hormone promotes red blood cell production in bone marrow. Varieties of erythropoietin biosimilar are being produced by recombinant DNA technology in cell cultures. The detection or quantification of these molecules are being performed by diff erent methods which some of theme such as Western blot and enzymelinked immunosorbent assay (ELISA) require sp...
متن کاملstudy the effects of low level laser diode on no production and healing of diabetic and cortisone acetate and normal wounded sd rats
nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...
15 صفحه اولMuscle creatine kinase isoenzyme expression in adult human brain.
Previous studies have suggested that MM creatine kinase is a muscle-specific protein and is not present in adult brain tissue. We have isolated a protein from human brain with an apparent molecular weight of 43,000 as determined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis which is identical to the muscle M creatine kinase isoenzyme subunit at all 30 sequenced amino acid residue...
