  • UV Talk Letter Vol. 07
    C101-E120 UV Talk Letter Vol.7 UV Talk Letter BioSpec-nano Life Science UV-VIS Spectrophotometer Life science research involves the handling of extracted and purified nucleic acids (DNA, RNA) in conducting PCR (Polymerase Chain Reaction), quantitative PCR, cloning, base sequence determination, DNA micro-array analysis, etc. Nucleic acid analysis using ultraviolet-visible spectrophotometers is widely conducted to successfully guide these processing operations. This document introduces the BioSpec-nano UV-VIS spectrophotometer, which provides simple and quick analysis of micro-level nucleic acids. 1. BioSpec-nano Features The BioSpec-nano, unlike conventional spectrophotometers, adopts an optical system that does not rely on the use of cells (cuvettes). The optical system comprises a xenon flash lamp, an upper window, a target platform (fiber optic element housing), holographic grating, and photodiode array detector. Measurement with the BioSpec-nano is conducted by automatically sandwiching the sample between the upper window and target to achieve a fixed pathlength (0.2 mm or 0.7 mm). This type of optical system allows measurement of ultra-small sample volumes in the range of 1 – 2 μL, as well as undiluted high-concentration samples, greatly facilitating the analysis operation. Cell washing and drying with conventional instruments is an extremely time-consuming, tedious task, which greatly impedes the analysis operation. With the BioSpec-nano, however, cleaning the liquid-contact surfaces (upper window and target) is accomplished by a simple wiping of the wet surfaces. The automated mounting mechanism, which establishes the appropriate pathlength, and the automated liquid-contact surface wiping feature allow true drop-and-click analysis.

  • Protein Biochemistry -Practical
    BCH303 [Practical] Biochemistry department Lab (6): Detection and quantitative estimation of proteins by different methods Aim: • To detect the presence of a protein or peptides using biuret test. • To determine the concentration of extracted protein by different methods. Introduction: The quantitation of protein content is important and has many applications in clinical laboratory practices and in research especially in the field of biochemistry. The accurate quantitation of protein content is a critical step in protein analysis. (1) Protein quantitation is often necessary before processing protein samples for isolation, separation and analysis by chromatographic, electrophoretic and immunochemical techniques. Depending on the accuracy required and the amount and purity of the protein available, different methods are appropriate for determining protein concentration. (2) The simplest and most direct assay method for proteins in solution is to measure the absorbance at 280 nm (UV range). Instead, several colorimetric and fluorescent, reagent-based protein assay techniques have been developed that are used by nearly every laboratory involved in protein research. Protein is added to the reagent, producing a color change or increased fluorescence in proportion to the amount added. The most commonly used techniques involve biuret test, Bradford test, bicinchoninic acid assay (BCA assay) and Lowry test. (2) No one reagent can be considered to be the ideal or best protein assay method. Each method has its advantages and disadvantages (Table 1). The choice among available protein assays is usually based on the compatibility of the protein assay method with the samples. Additionally, one must consider potential interfering substances included in samples that may affect certain assay methods, as well as the accuracy, reproducibility and incubation time desired.

This review aims to discuss the analysis techniques of protein and amino acid in food and agricultural products. The qualitative analysis can be conducted using the Hopkins-Cole, Xanthoproteic, Millon, Nitroprusside, and Sakaguchi test. In contrast, the quantitative analysis of proteins can use the Kjehldahl, Biuret, Lowry, UV Spectrophotometry, and Turbidimetry. It also discussed the immunohistochemical techniques to identify cellular or tissue constituents (antigens) by staining techniques, while Formol titration measures the hydrolysis of proteins and N-amino quickly. The amino acids can be analyzed by microbiological methods, colorimetric, high-performance liquid chromatography (HPLC), and gravimetric techniques. These methods/techniques can be chosen according to the type of sample and the purpose of the analysis so that the results can be obtained accurately.

  • CHE 453 Lab 1A: the Extraction and Purification of Wheat Germ Acid
    CSUDH Biochemistry II Laboratory – CHE 453 Lab 1A: The Extraction and Purification of Wheat Germ Acid Phosphatase INTRODUCTION Protein Isolation Proteins play such a variety of important roles in the living cell that it should be no surprise that an enormous amount time and effort has been spent in elucidating the structure and function of these versatile macromolecules. An absolute prerequisite to meaningful progress in the study of any protein is an ample supply of highly purified material. Unfortunately, few if any proteins exist in nature at the desired concentration or at the degree of purity required for such detailed analysis. Consequently, it has been necessary that laboratory procedures be developed for the extraction, concentration, and purification of cellular proteins. The development of these procedures, which has taken a considerable period of time, has been hampered by the fact that the concentration of any given protein in a cell is usually extremely low (less than 0.01% of the total mass of the cell) and further complicated by the presence of many other macromolecules (nucleic acids, carbohydrates, etc.) which must be eliminated. The task of a biochemist who chooses to develop an isolation technique for large amounts of purified protein is a difficult one and would typically include the following considerations: The development or selection of a simple assay procedure that specifically demonstrates the presence and concentration of the protein in question. The choice of materiel from which the protein can be isolated. The overriding factors in this choice typically are the absolute concentration of the protein in a given natural source and the cost and availability of the material.
