Biotium HCG-intact(HCGab/52), CF594 conjugate, 0.1mg/mL
This MAb is a very special because it reacts ONLY with the intact-HCG and not with either free alpha- or free beta-chain of HCG. HCG is a glycoprotein and is composed of two non-identical, non-covalently linked polypeptide chains designated as the alpha and beta subunits. The alpha subunit is identical to that of thyroid stimulating hormone (TSH), follicle stimulating hormone (FSH), and luteinizing hormone (LH). HCG is secreted in large quantities by normal trophoblasts. It is present only in trace amounts in non-pregnant urine and sera but rises sharply during pregnancy. HCG MAb detects cells and tumors of trophoblastic origin such as choriocarcinoma. Large cell carcinoma and adenocarcinoma of the lung demonstrate anti-hCG positivity in 90% and 60% of cases respectively. 20% of lung squamous cell carcinomas are positive. HCG expression by non-trophoblastic tumors may indicate aggressive behavior.Primary antibodies are available purified, or with a selection of fluorescent CF

Gold Biotechnology Inc Bicine 500 g
Bicine is a buffering agent used in biochemistry and molecular biology that was selected and described by Good et al. It is a zwitterionic, bis(2-hydroxyethyl)amine buffer that is useful for a pH range of 7.6 – 9.0. It is commonly used in protein crystallization, in the study of enzymatic reactions, and for electrophoresis. It is used in thin layer ion exchange chromatography for protein resolution, as well as a multiphasic buffer system for SDS-PAGE of proteins. It is soluble in water at 0°C up to 1.1 M. Bicine forms a complex with most common metals so stability constants and concentrations should be taken into consideration when choosing this buffer.
