Exosomes are membrane-wrapped extracellular vesicles (EVs) with a diameter of approximately 40-160 nm, possessing a lipid bilayer structure. They are naturally present in blood, urine, cerebrospinal fluid, and the supernatant of cultured cells in vitro, and almost all types of cells can produce and release exosomes.
There are different opinions on the detection and classification of ELISA, and different literatures have different classification opinions in terms of principle or operation. Here we divide ELISA into the following four categories, and then explain each category in detail: (1) direct ELISA; (2) indirect ELISA; (3) Sandwich ELISA; (4) Competition inhibits ELISA. Other ELISA are affiliated with, or derived from, a combination of these four types of ELISA.
Endoplasmic Reticulum Stress Secretory and transmembrane proteins are synthesized on polysomes and translocate into the endoplasmic reticulum (ER) where they are often modified by the formation of disulfide bonds, amino-linked glycosylation and folding. The ER contains a pool of molecular chaperone proteins including calnexin, BiP and protein disulfide isomerase (PDI).
Estrogen receptor α (ERα), a member of the steroid receptor superfamily, contains highly conserved DNA binding and ligand binding domains. Through its estrogen-independent and estrogen-dependent activation domains (Estrogen receptor αAF-1 and AF-2, respectively), ERα regulates transcription by recruiting coactivator proteins and interacting with general transcriptional machinery. Phosphorylation at multiple sites provides an important mechanism to regulate ERα activity.
Selecting the appropriate secondary antibody is the core link to ensure the accuracy of experimental results, focusing on the characteristics of the primary antibody, experimental methods and detection needs, mainly considering the following factors: 1. Match the source species of the primary antibody; 2. Match the antibody subtype of the primary antibody; 3. Select markers according to the experimental method; 4. Pay attention to specificity and purification methods; 5. Avoid species cross-reactivity
The top 100 antibodies in the 2024 antibody market dataset are ranked based on antibody citation analysis. They provide a unique and quantified panoramic view of the antibody market and serve as an important reference in the field of antibody research and application.
Epithelial-mesenchymal transition (EMT) is an essential process during development whereby epithelial cells acquire mesenchymal, fibroblast-like properties and display reduced intracellular adhesion and increased motility. This is a critical feature of normal embryonic development, which is also utilized by malignant epithelial tumors to spread beyond their origin.

Mitochondria are the main site for ATP production in animal and plant cells, and are important organelles that promote cellular energy conversion and participate in cell apoptosis. Mitochondria store the energy generated during respiratory oxidation in the inner membrane of mitochondria as electrochemical potential energy, causing asymmetric distribution of proton and other ion concentrations on both sides of the inner membrane and forming the mitochondrial membrane potential (MMP, Δ PSI m). Normal MMP is a prerequisite for maintaining mitochondrial oxidative phosphorylation and producing adenosine triphosphate. The stability of MMP is beneficial for maintaining normal physiological functions of cells.
