What are Dyed Polystyrene Latex Particles? Polystyrene particles (PSP) are commercially available in different sizes, ranging from 15 nanometers to several micrometers, with narrow size distributions and various surface chemistries. Additionally, polystyrene is generally considered inert and nontoxic, making it safe for use in a variety of biological assays. Dyed polystyrene latex particles or ...
For decades, the medical field has seen incredible advances in technology – from new diagnostic capabilities to improved treatments that have saved countless lives. One of these impressive solutions is radiopaque markers – small devices used to diagnose and treat a variety of conditions, ranging from cardiovascular problems to cancer. Not only do they help doctors better understand ...
With the deepening of the research on the three-dimensional structure, binding characteristics and stability of biotin and avidin, the application of BAS and its related technologies in a variety of automated immunoassay techniques has further promoted the development of sensitive, rapid and accurate determination techniques for some trace substances in plasma and body fluids such as small ...
Fluorescent Microspheres for Protein Detection Multi-color quantum dot-bound microspheres have been widely proven to be used for the simultaneous detection of multiple antigens, including IgG, tumor markers, and pathogenic markers. Two different antigens can be detected simultaneously using upconverting nanoparticles and magnetic ...
Early detection and treatment are of significant importance in tumor screening. VEGF is produced in large quantities during the transition of tumor cell clusters into solid tumors, which often occurs in the Tis and T1 stages of the tumor. ...
For example, the enzyme lactate dehydrogenase (LDH) is often used as a marker for cancer progression, as increased levels of LDH in the blood can indicate tumor growth. ...
Glycosylation of immune system molecules has been explored for disease marker research. Glycosylation can regulate tumor proliferation, invasion, metastasis, and angiogenesis. Abnormal glycosylation is often considered a sign of cancer. Most tumor markers approved by the FDA are glycoprotein or glycan antigens. ...
However, given the surgical site often lies in soft tissue, exact identification of the native tumor bed can present some difficulty for radiation planning. The surgical and radiation oncology team at Providence Mission Hospital (Mission Viejo, Ca) elected to use a novel tumor bed marker called VeraForm for a sarcomatoid carcinoma. ...
Despite years of study focused on the tumor suppressor p53, little is understood about its functions in normal, differentiated cells. We found that p53 directly interacts with lysine-specific demethylase 1 (LSD1) to alter chromatin structure and confer developmental repression of the tumor marker alpha-fetoprotein (AFP). Chromatin ...
