Self-contained, disposable devices for filtering fibrin and separating serum and plasma from centrifuged whole blood specimens contained in standard 16, 13, or 10.25mm I.D. evacuated blood collection tubes. Technique reduces second centrifugations, tube labeling, and sample preparation time. With collection tube in vertical position, insert stopper end of the filter sampler at a 45° angle and push gently down to just above clot. Filtered serum or plasma will rise into the barrel for analysis.

Proinsulin C-peptide is the sequence of C peptide as it exists within proinsulin, the precursor to insulin which consists of insulin A chain, insulin B chain and C peptide (connecting peptide). In proinsulin, C peptide provides a means to ensure correct folding and assembly of the A and B chains. It is eventually cleaved away by proteases PC2, PC1/3 and CPE, at the flanking Arg-Arg and Lys-Arg basic residues (Arg-Arg-C peptide-Lys-Arg). Although C peptide is not present in mature insulin, it is stored in secretory granules, and eventually released into the bloodstream together with insulin in nearly equimolar amounts. Whereas insulin is metabolized quickly from circulation, C-peptide exhibits a slow turnover rate (>30 minutes). The measurement of the C-peptide is an important test for the β-cell function. In the red blood cells of type 2 diabetic patients, Na+,K+, ATPase activity is strongly related to blood C-peptide levels. C-peptide signal transduction in human renal tubular cells involves the activation of phospholipase C and PKC-δ and PKC-varepsilon, as well as RhoA, followed by phosphorylation of ERK1/2 and JNK and a parallel activation of Akt. C-peptide shows specific binding to a G-protein-coupled membrane binding site, resulting in Ca2+ influx, activation of mitogen-activated protein kinase signalling pathways and stimulation of Na+, K+ ATPase and endothelial nitric oxide synthase.

Deoxyribonuclease from beef pancreas, DNase I, was first crystallized by Kunitz. It is an endonuclease which splits phosphodiester linkages, preferentially adjacent to a pyrimidine nucleotide yielding 5'-phosphate terminated polynucleotides with a free hydroxyl group on position 3'. The average chain of limit digest is a tetranucleotide. DNase I acts upon single chain DNA, and upon double-stranded DNA and chromatin. In the latter case, although histones restrict susceptibility to nuclease action, over a period of time nearly all chromatin DNA is acted upon. According to Mirsky and Silverman, this could result from the looseness of histone attachment to DNA. They found that lysine-rich histones more effectively block DNase access to DNA than arginine-rich histones. Billing and Bonner suggest that DNase attacks the histone-free strand of chromatin DNA. Schmidt, et. al.indicate that hydrolysis of the histone-free region of DNA strands accounts for the initial rapid action of the enzyme on chromatin. Bollum reports degradation of synthetic homopolymer complexes by DNase I. The intracellular functions of the enzyme are probably controlled by a DNase inhibitor, which according to Lazarides and Lindberg is actin.
