Introduction
One of the most widely used analytical biochemical techniques is chromatography, which separates molecules based on their chemical and physical properties. High-performance liquid chromatography (HPLC) and gas chromatography (GC) are commonly used [1- 6] to separate and quantify small molecules such as amino acids, nucleotides, and metabolites. HPLC is also used for protein separation and purification. Another important analytical biochemical technique is electrophoresis, which separates molecules based on their size and charge. Gel electrophoresis is commonly used for separating proteins and nucleic acids. Polyacrylamide gel electrophoresis (PAGE) and sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDSPAGE) are used to separate proteins, while agarose gel electrophoresis is used for nucleic acid separation. Spectroscopy is another essential analytical biochemical technique that involves the interaction of light with matter. Ultraviolet-visible (UV-Vis) spectroscopy is used to measure the absorbance of molecules such as nucleic acids and proteins, while fluorescence spectroscopy is used to detect and quantify molecules such as fluorophores and proteins. Enzyme-linked immunosorbent assay (ELISA) is a powerful analytical biochemical technique used to detect and quantify proteins or antibodies. ELISA is widely used in diagnostics, drug discovery, and basic research. Mass spectrometry (MS) is a highly sensitive and versatile analytical biochemical technique used to identify and quantify molecules based on their mass-to-charge ratio. MS is used for protein identification, metabolomics, and lipidomics. Analytical biochemical techniques refer to a set of methods used to identify, quantify, and analyze the chemical and physical properties of biological molecules such as proteins, nucleic acids, and metabolites. These techniques are essential for understanding the molecular mechanisms that govern biological processes, as well as for the development of new diagnostic tools, therapies, and drugs. Analytical biochemical techniques are widely used in fields such as biochemistry, molecular biology, pharmacology, and biotechnology. The development of analytical biochemical techniques has been driven by the need to understand the complex and dynamic nature of biological systems at the molecular level. The biochemical molecules that make up these systems are highly diverse and complex; requiring sophisticated analytical methods to study them. The development of these techniques has been facilitated by advances in technology, such as the miniaturization of instruments, the development [1-4] of more sensitive detectors, and the advent of high-throughput methods. In this context, the field of analytical biochemical techniques is constantly evolving, with new techniques and technologies emerging regularly. These innovations have enabled researchers to study biological systems at an unprecedented level of detail, leading to new insights into the molecular mechanisms underlying diseases and the development of more effective diagnostic and therapeutic approaches. In this introduction, we will provide an overview of some of the most commonly used analytical biochemical techniques and their applications. We will also highlight some of the emerging trends and innovations in the field (Table 1).

Materials and Methods Analytical Biochemical Techniques
The choice of materials and methods used in analytical biochemical techniques depends on the specific research question and the biochemical molecules being studied. However, there are some common materials and methods [4-9] that are widely used in the field. Materials commonly used in analytical biochemical techniques include buffers, reagents, solvents, and standards. Buffers are used to maintain a constant pH and stabilize biochemical molecules during experiments. Reagents are used to detect, identify, and quantify specific biochemical molecules. Solvents are used to extract, purify, and analyze biochemical molecules. Standards are used to calibrate instruments and validate results. The methods used in analytical biochemical techniques can be broadly classified into separation, detection, and quantification methods. Separation methods are used to separate biochemical molecules based on their chemical and physical properties. Chromatography is a widely used separation method that involves the separation of molecules based on their affinity for a stationary phase (such as a column) and a mobile phase (such as a solvent). High-performance liquid chromatography (HPLC), gas chromatography (GC), and ion-exchange chromatoraphy (IEC) are commonly used in the field. Detection methods are used to detect the presence of biochemical molecules. Spectroscopy is a commonly used detection method that involves the interaction of light with matter. Ultraviolet-visible (UV-Vis) spectroscopy is used to measure the absorbance of molecules such as nucleic acids and proteins, while fluorescence spectroscopy is used to detect and quantify molecules such as fluorophores and proteins. Quantification methods are used to measure the concentration of biochemical molecules. Enzyme-linked immunosorbent assay (ELISA) is a commonly used quantification method that involves the use of antibodies to detect and quantify proteins or other biomolecules. Mass spectrometry (MS) is another commonly used quantification method that measures the mass-to-charge ratio of molecules and is used for protein identification, metabolomics, and lipidomics. In addition to these methods, there are emerging techniques and technologies in the field of analytical biochemical techniques, such as microfluidics, biosensors, and computational methods. These innovations are enabling researchers to study biochemical molecules with greater sensitivity, accuracy, and speed.
In summary, the choice of materials and methods in analytical biochemical techniques depends on the specific research question and the biochemical molecules being studied. Separation, detection, and quantification methods are commonly used in the field, with emerging techniques and technologies offering new possibilities for advancing our understanding of complex biological systems.

Specificity: Analytical biochemical techniques can be highly specific, but they may not be able to distinguish between closely related molecules. For example, mass spectrometry may not be able to distinguish between two molecules with similar mass-to-charge ratios.
Sample preparation: Analytical biochemical techniques often require extensive sample preparation, which can be time-consuming and costly. Sample preparation can also introduce artifacts or contaminants that can interfere with the accuracy of the results.
Equipment and expertise: Many analytical biochemical techniques require specialized equipment and expertise to perform and analyze the data. This can limit their accessibility to smaller laboratories or institutions with limited resources.
Interference: Analytical biochemical techniques can be subject to interference from other molecules or contaminants in the sample. For example, fluorescence-based assays can be affected by autofluorescence from the sample or background fluorescence from the environment.
Complexity: Biological samples are often complex mixtures of many different molecules, which can make it difficult to isolate and analyze specific biomolecules of interest. This can lead to false positive or false negative results. Overall, it is important to carefully consider the strengths and limitations of analytical biochemical techniques when selecting an appropriate method for a particular application. Researchers should also carefully validate their results and consider multiple lines of evidence to confirm their finding.
