Histones are basic structural proteins of chromosomes in eukaryotes, rich in positively charged basic amino acids (lysine and arginine), which can tightly bind to acidic DNA and are responsible for DNA packaging and regulation of gene expression.

There is no "universal loading control", only the most suitable loading control for your experimental conditions. The key is to make a reasonable selection based on your cell line/tissue source, treatment conditions, and the molecular weight of the target protein.

It is the first to identify a novel form of programmed necrosis characterized by sodium overload — NECSO(Necrosis by Sodium Overload). The research defines transient receptor potential cation channel TRPM4 as the core regulator of this process, elucidates its molecular mechanism, species specificity and disease association, and identifies the first inhibitor of NECSO, providing a novel target and strategy for cell death regulation and the treatment of related diseases.

In Western Blot (WB) experiments, selecting appropriate antibodies is key to ensuring experimental success.

Antibody purification is a process that relies on the biological characteristics of antibodies—such as the charge, size, and hydrophobicity of antibody molecules—to select appropriate methods and isolate target antibodies from complex mixtures through multi-step chromatographic techniques.

During the preparation of monoclonal antibodies, there are two screening processes. The first is to screen for hybridoma cells, and the second is to further screen for hybridoma cells that produce specific antibodies.

Antibodies, known as immunoglobulins, are typically "Y"-shaped. In most mammals, immunoglobulins consist of five types: IgG, IgM, IgA, IgD, and IgE, which differ from one another in size, charge, amino acid composition, and carbohydrate content. Meanwhile, each type of antibody has subclasses with heterogeneity among them; for instance, the four subtypes of IgG (IgG1, IgG2, IgG3, IgG4) in humans and mice do not share homology. Besides, IgY antibodies are also present in avian species.

Western Blot technology is a core technical method for the detection and quantitative analysis of specific proteins in the fields of molecular biology and biochemistry research, and its application is widespread and indispensable. In the experimental workflow of Western Blot, the selection of transfer membranes is directly related to the accuracy, repeatability, and reliability of experimental results, and it is one of the key links that affect the success or failure of the experiment. Currently, the most commonly used transfer membranes in scientific research practice mainly include two types: polyvinylidene fluoride membranes (PVDF membranes) and nitrocellulose membranes (NC membranes). These two types of transfer membranes have different focuses in terms of material properties, applicable scenarios, and other aspects, and there is no absolute distinction between advantages and disadvantages. This article will elaborate on the key properties and application points of these two types of transfer membranes in detail.

Loading control antibodies serve as the "benchmark" in experiments. They are used to calibrate differences in sample quantity and assess the stability of the experimental system. Selecting appropriate Loading control antibodies is a crucial step in ensuring data reliability, and is particularly vital for research on gene expression, protein quantification, and other related studies in university scientific research. How to correctly select Loading control antibodies? The following points can be used as a reference.

Compared with traditional antibody preparation methods, the antibodies produced by recombinant antibody technology exhibit more prominent application advantages due to their unique technical characteristics, providing strong support for research and practice in related fields.
