Abstract 1. The serum from unpreserved rubber (Hevea brasiliensis) latex contains seven electrophoretically distinct protein components. The proteins from whole serum originating in Sumatra and Florida give very similar results in electrophoresis experiments. 2. The relationship between electrophoretic mobility and pH has been determined for five of the seven protein components of unpreserved total latex serum. The results are considerably different from those reported by workers with ammonia-preserved latex, and tend to clarify observed differences in the stability behavior of unpreserved and preserved latex. 3. Ammonia-preservation treatment rapidly alters the electrophoretic behavior of the native protein components of latex serum and reduces the number of resolvable components from seven to two. 4. The preparation of dry latex protein from rubber-free latex serum can be accomplished by the vacuum sublimation of frozen serum. This process does not appear to produce important changes in the electrophoretic properties of the total serum proteins. 5. Minor modifications of the electrodes and of the standard illumination system in the electrophoresis apparatus are described.

Introduction Stroke is a common complication in children with tuberculous meningitis (TBM). Host proteins may give us insight into the mechanisms of stroke in TBM and serve as biomarkers for detection of stroke, however, they have not been widely explored. In this study, we compared the concentrations of cerebrospinal fluid (CSF) and serum proteins between children who had TBM-related stroke and children with TBM without stroke. Methods We collected CSF and serum from 47 children consecutively admitted to the Tygerberg Academic Hospital in Cape Town, South Africa between November 2016, and November 2017, on suspicion of having TBM. A multiplex platform was used to measure the concentrations of 69 host proteins in CSF and serum from all study participants. Results After classification of study participants, 23 (48.9%) out of the 47 study participants were diagnosed with TBM, of which 14 (60.9%) demonstrated radiological arterial ischemic infarction. The levels of lipocalin-2, sRAGE, IP-10/ CXCL10, sVCAM-1, MMP-1, and PDGF-AA in CSF samples and the levels of D-dimer, ADAMTS13, SAA, ferritin, MCP-1/ CCL2, GDF-15 and IL-13 in serum samples were statistically different between children who had TBM-related stroke and children with TBM without stroke. After correcting for multiple testing, only the levels of sVCAM-1, MMP-1, sRAGE, and IP-10/ CXCL10 in CSF were statistically different between the two groups. CSF and serum protein biosignatures indicated stroke in children diagnosed with TBM with up to 100% sensitivity and 88.9% specificity. Conclusion Serum and CSF proteins may serve as biomarkers for identifying individuals with stroke amongst children diagnosed with TBM at admission and may guide us to understand the biology of stroke in TBM. This was a pilot study, and thus further investigations in larger studies are needed.

Immunochemical Techniques

By means of immunochemical techniques, the protein components of the water-soluble fraction (WSF) of the egg yolk have been examined in the unincubated egg and during incubation. Anti-ovalbumin and anti-total adult chicken serum antisera have been employed. Ovalbumin can be detected in the unincubated WSF as well as during incubation; its concentration seems to increase during incubation. In the WSF of the unincubated egg, six proteins immunologically related to adult serum proteins can be detected. They correspond to α-livetin, α1-globulin, β-livetin, ovotransferrin (conalbumin) and γ-livetin (two components). β-Livetin disappears after the 14th day of incubation while the other components can be demonstrated till hatching. The findings are discussed in relation to the data available in the literature. The findings are discussed in relation to the data available in the literature.

Abstract Measurement of immunoglobulins (Ig) and of complement component C3 in human serum by automated and manual nephelometric techniques is tedious, and the effective linear range is too narrow. We describe a laser nephelometer/reagent system for measuring serum proteins by the use of forward light scatter (which enhances the ratio of reaction/blank), electronic blank subtraction, laser light (632 nm), and electronic signal selection. We report data establishing the range of linearity for immunoglobulins IgG, IgA, IgM, and complement C3 with this system, and correlations with results by a radial immunodiffusion. We also compared an electroimmunodiffusion system for quantitation of albumin and IgG in cerebrospinal fluid to our technique. The nephelometric system described provides a rapid, accurate, precise, and objective way to measure immunoglobulins and C3.

In unstimulated saliva, total protein concentration averaged 186 mg per 100 ml and amylase activity 146 units per 100 ml. The protein concentration was lower in the early morning than at midday. After dilute acetic acid stimulation, both total protein concentration and amylase activity were increased but the concentrations were not affected by rates of secretion above 0.1 ml per minute. Unlike protein, the potassium concentration fell with stimulation.Using zone electrophoresis on filter paper, as many as nine protein components were found, none of which corresponded to the serum proteins. The amylase activity was restricted to a component of low mobility which moved to the anode. There were two or three bands containing glycoproteins; all moved towards the cathode. There were qualitative and quantitative differences between stimulated and unstimulated secretions. Saliva collected 2 or 24 hours after a tracer dose of I131 showed less than 1% residual radioactivity after dialysis or treatment with an anion exchange resin, indicating that little if any of the salivary iodide is organically bound.

Abstract Albumin and other serum-derived proteins were removed from several types of body fluids by affinity chromatography, to facilitate detection of trace or non-serum-derived proteins in two-dimensional electrophoresis patterns. Albumin was removed by the dye Cibacron Blue F3G-A coupled to Sepharose. Two-dimensional patterns of albumin-depleted serum lack the large albumin spot, and several families of spots become visible that ordinarily are partly or totally hidden by it. However, other proteins also bind to Cibacron Blue. Most serum proteins, including albumin, were effectively removed by anti-human serum antibodies coupled to Sepharose. Two-dimensional patterns of serum-depleted cerebrospinal fluid exhibit five clusters of probable nervous-system protein families not detected in serum. One additional family, probably antigenically related to transferrin, was removed by the affinity step. Two-dimensional patterns of serum-depleted prostatic fluid exhibit five major non-serum families, two of which may be creatine kinase B subunits and prostatic acid phosphatase. Two-dimensional patterns of serum-depleted malignant effusions exhibit one or more of three proteins that possibly are tumor products. Pattern matching suggests the presence of one non-serum-derived protein family common to cerebrospinal fluid, prostatic fluid, and malignant effusions. Prostatic fluid and malignant effusions have in common as many as three non-serum families of proteins.
