Detection principle: ELISA: Use enzyme-labeled antibodies or antigens to produce chromogenic products through enzyme catalysis, and then quantitatively analyze target molecules by measuring the optical density of the chromogenic products. CLIA: Directly detects the light produced by a chemiluminescent reaction, without the need for enzyme catalysis, and uses a chemiluminescent substr...
Chemiluminescence is a chemical reaction that produces light without heating. It is widely used to detect and analyze various substances, such as environmental pollutants, food additives, etc. CLIA (Chemiluminescence Immunoassay) is a highly sensitive analytical technology that combines the principles of immunoassay and chemiluminescence to detect specific molecules, such as disease ...
Cytokines are a type of small molecule proteins with broad biological activities that are synthesized and secreted by immune cells (such as monocytes, macrophages, T cells, B cells, NK cells, etc.) and certain non-immune cells (endothelial cells, epithelial cells, fibroblasts, etc.) upon stimulation. 1. Gram-negative (G-) and Gram-positive (G+) bacterial infections can be differentiated Cytokines ...
1. How can vitamin D deficiency impact overall well-being? ♣ Vitamin D deficiency rickets (nutritional rickets) Vitamin D deficiency during childhood can lead to rickets in children, causing growth delays and skeletal deformities. Essentially, Vitamin D deficiency rickets is a form of osteomalacia. The onset of this condition is gradual, often occurring in infants between the ages of 3 month...
♣ Vitamin B12, also known as adenosylcobalamin or cyanocobalamin, is an essential water-soluble vitamin. It plays a key role in the body, including maintaining the normal function of the nervous system, promoting the production of red blood cells, and supporting DNA synthesis. The main difference between active B12 and B12 lies in their chemical forms and bioavailability. 1. Chemical form: B...
1. The necessity of developing cytokines in the Department of Hematology In the treatment of some diseases, such as bloodstream infection, hemophagocytic syndrome (HLH), leukemia, sepsis, etc., the inflammatory response status of patients is mostly detected, so cytokine detection plays an important role in the selection, adjustment and prognosis evaluation of treatment regimens. ⇔Hemophagocyt...
Cytokines are a general term for a class of small molecule polypeptides or glycoproteins with extensive biological activity synthesized and secreted by immune cells or some non-immune cells, which have the functions of regulating the body's immune function, mediating inflammatory responses, participating in tissue repair, and promoting wound healing. In the development of tumor diseases, cytokines...
In vitro diagnostics (IVD), refers to products and services that obtain clinical diagnostic information by testing human samples (various body fluids, cells, tissue samples, etc.) outside the human body, and then judge diseases or body functions. In vitro diagnostics is known as the "doctor's eye" in the medical field, and is an important part of modern laboratory medicine, and its clinical ...
