Arteriosclerosis and thrombosis : a journal of vascular biology, 13(1), 78-83 (1993-01-01)
In this study we evaluated two different 99mTc-labeling techniques to produce 99mTc-low density lipoprotein (99mTc-LDL) suitable for the scintigraphic delineation of experimental atherosclerotic lesions. The two methods are 1) a procedure that uses stannous chloride and sodium borohydride (borohydride method)

Sialoglycoproteins of rat epididymal fluid and spermatozoa were radiolabelled by the NaIO4/KB3H4 method. At least 10 sialoglycoproteins of the epididymal fluids could be consistently demonstrated by polyacrylamide gel electrophoresis in sodium dodecyl sulphate. Two major ones (Mr 21000 and 66000)

Bacterial 5-oxoprolinase is composed of two protein components: Component A, which catalyzes 5-oxoproline-dependent ATP-hydrolysis and Component B, which couples the hydrolysis of ATP with the decyclization of 5-oxoproline to form glutamate (Seddon, A. P., Li, L., and Meister, A. (1984)
