Product Name: HCG-beta Antibody [HCGb/459]
Species Reactivity: Human
Tested Applications: ELISA, IHC
Applications: ELISA: use BSA-free format (2)IHC (FFPE): 0.5-1 ug/ml for 30 min at RT (1)Prediluted format : incubate for 30 min at RT (3)The concentration stated for each application is a general starting point. Variations in protocols, secondaries and substrates may require the HCG-beta antibody to be titered up or down for optimal performance.1. Staining of formalin-fixed tissues REQUIRES boiling tissue sections in 10mM citrate buffer, pH 6.0, for 10-20 min followed by cooling at RT for 20 minutes.2. Clone HCGb/459 (recommended capture) will pair with clones HCGb/211 and HCGb/54 (recommended detect) by ELISA.3. The prediluted format is supplied in a dropper bottle and is optimized for use in IHC. After epitope retrieval step (if required), drip mAb solution onto the tissue section and incubate at RT for 30 min.
User Note: Optimal dilutions for each application to be determined by the researcher

Background: This antibody reacts with a protein of 22kDa, identified as beta subunit of HCG. It does not cross react with the alpha subunit. HCG is a glycoprotein which 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 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-beta antibody detects cells and tumors of trophoblastic origin such as choriocarcinoma. Large cell carcinoma and adenocarcinoma of the lung demonstrate antibody 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.
