Protein Quantitation and Analysis of Purity.

The accurate quantitation of proteins and an analysis of their purity is essential in numerous areas of scientific research and is a critical factor in many clinical applications. The large number and variety of techniques employed for this purpose is therefore not surprising. The selection of a suitable assay is dependent on such factors as the level of sensitivity required, the presence of interfering agents, and the composition of the protein itself.

Poly-Histidine-Tagged Protein Purification Using Immobilized Metal Affinity Chromatography (IMAC).

His-tagging is the most widespread and versatile strategy used to purify recombinant proteins for biochemical and structural studies. Recombinant DNA methods are first used to engineer the addition of a short tract of poly-histidine tag (His-tag) to the N-terminus or C-terminus of a target protein. The His-tag is then exploited to enable purification of the "tagged" protein by immobilized metal affinity chromatography (IMAC).

Tagging Recombinant Proteins to Enhance Solubility and Aid Purification.

Protein fusion technology has had a major impact on the efficient production and purification of individual recombinant proteins. The use of genetically engineered affinity and solubility-enhancing polypeptide "tags" has a long history, and there is a considerable repertoire of these that can be used to address issues related to the expression, stability, solubility, folding, and purification of their fusion partner. In the case of large-scale proteomic studies, the development of purification procedures tailored to individual proteins is not practicable, and affinity tags have become indispensable tools for structural and functional proteomic initiatives that involve the expression of many proteins in parallel.

A Synopsis of Proteins and Their Purification.

The goal of protein purification is to separate a specific protein from all other biomolecules. Classical chromatographic procedures have been designed to exploit particular distinguishing features of individual target proteins, such as size, shape, physicochemical properties, and binding affinity. Advances in molecular biology and bioinformatics have positively contributed at every level to the challenge of purifying individual proteins and more recently have led to the development of high-throughput proteomic platforms.

Improving elementary students' knowledge and behavior to prevent traumatic injury: the impact of a behavioral skills training model delivered by aspirational role models.

Trauma is the leading cause of childhood morbidity and mortality annually in the USA, accounting for 11% of deaths, most commonly due to car crashes, suffocation, drowning, and falls. Prevention is paramount for reducing the incidence of these injuries. As an adult level 1 and pediatric level 2 trauma center, there is a commitment to injury prevention through outreach and education.

A structural explanation for the mechanism and specificity of plant branching enzymes I and IIb.

Branching enzymes (BEs) are essential in the biosynthesis of starch and glycogen and play critical roles in determining the fine structure of these polymers. The substrates of these BEs are long carbohydrate chains that interact with these enzymes via multiple binding sites on the enzyme's surface. By controlling the branched-chain length distribution, BEs can mediate the physiological properties of starch and glycogen moieties; however, the mechanism and structural determinants of this specificity remain mysterious.

A double-spike MC TIMS measurement procedure for low-amount Ca isotopic analysis of limited biological tissue samples.

The application of Ca isotopic analysis in biomedical studies has great potential to identify changes in Ca metabolism and bone metabolism. Reliable measurement of Ca isotope-amount ratios is challenging considering limited Ca amounts and significant procedural blank levels. In this study, Ca purification was performed using the DGA Resin, optimized for low procedural blanks and separation of Ca from matrix elements and isobaric interferences (Na, Mg, K, Ti, Fe, Ba), while maintaining quasi-quantitative recoveries which are sufficient since a Ca-Ca double-spike (DS) was applied.

The Utility of Lower Extremity Screening Duplex for the Detection of Deep Vein Thrombosis in Trauma.
