• • What Does the Protein Sequencing Result Graph Look Like?

  Protein sequencing is a fundamental step in biological research, the main goal of which is to determine the amino acid sequence, that is, the primary structure of the protein. The sequencing results are usually presented graphically to help researchers better understand the structure and function of the protein.   General Style Generally speaking, the graphical representation of protein sequencing results mainly includes two parts: the amino acid sequence and a pairing diagram.

• • N-Terminal Closed Sequencing

  In the field of biological research, sequencing is a technique used to determine the exact sequence of biomolecules such as DNA, RNA, or proteins. While there are various forms of sequencing, an important distinction lies in whether all sequences are determined or only specific parts are targeted. N-terminal sequencing is a unique form of sequencing that primarily focuses on one specific endpoint of the sequence—the N-terminus.

• • Bokes AB Antibody Sequencing

  Boxcab Antibody Sequencing is an important experimental method commonly used in studying cellular and protein responses. In biomedical research, antibodies are a powerful tool used in the detection and quantification of target antigens. However, a comprehensive understanding of the antibody requires knowledge of its amino acid sequence, which can be achieved through antibody sequencing.

• • Protein Content Determination by Lowry Method Standard Curve

  The Lowry method, also known as the Lowry method, is a commonly used biochemical analytical method for determining total protein content. The method was proposed by Oliver H. Lowry et al. in 1951. It is based on the absorbance of the complex produced by the reaction of protein with phenol and copper ions at a specific wavelength, thereby calculating the concentration of the protein.

• • Mitochondrial Protein Sequencing

  Mitochondria are a unique type of organelle present within cells, serving as the primary source of energy within living organisms. They are responsible for several life-sustaining processes, including energy production, reducing free radicals, and maintaining cellular signaling. Proteins within the mitochondria play a key role in these processes.

• • Collagen Protein Detection Service Mass Spectrometry

  Collagen is the most abundant protein in animal tissues, accounting for one-third of the total protein content. Due to its crucial role in many biological processes, such as the structure and stability of the extracellular matrix, the analysis and detection of collagen have become an important area of research in the scientific field. In recent years, mass spectrometry has played a significant role in the detection and identification of collagen.

• • Protein-Protein Interaction Sequencing

  In-depth research on protein interaction plays a crucial role in life science research. Proteins are the main bearers of life activities, and their interactions form a complex molecular network within biological cells. Protein-Protein Interaction Sequencing (PPI-Seq) is an emerging technology. Based on high-throughput sequencing, it allows researchers to explore protein interactions at the whole genome level.

• • Nano Antibody Sequencing

  When we talk about antibody sequencing, we often think of issues related to disease treatment and improving human health. Nanobody sequencing provides us with a more precise and efficient solution. Nanobodies, also known as single-domain antibodies, are antibodies composed of a single functional domain.

• • How to Interpret De Novo Sequencing in Protein Mass Spectrometry?

  Protein sequencing by mass spectrometry is an effective way to analyze protein sequences. It is widely used in biological research, including disease research, drug discovery, and other areas. This article will focus on de novo protein sequencing by mass spectrometry and its spectrum resolution technology.   De novo protein sequencing is a method to directly obtain the amino acid sequence of a protein or peptide without relying on known protein sequence databases, using mass spectrometry techniques.

• • How Much Protein Is Needed for Edman Sequencing?

  In Edman protein sequencing, the amount of protein typically needed depends on various factors, such as the sensitivity of the sequencing equipment, the purity of the protein, and the complexity of the sequence. Traditionally, the Edman degradation method is used to determine the amino acid sequence of proteins or polypeptides, usually requiring about 1 to 100 picomoles (pmol) of protein sample.
