- IMMUNOGEN: Recombinant protein was used as the immunogen for this HCG-beta antibody.
- CONJUGATE: Unconjugated
- TESTED APPLICATIONS: ELISA, IHC
- APPLICATION NOTE: ELISA: use BSA-free format (1)
IHC (FFPE): 0.5-1 ug/ml for 30 min at RT (2)
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. Clone HCGb/54 (recommended detect) will pair with clones HCGb/211 (recommended capture) and HCGb/459 by ELISA.
2. 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.
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.

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.
