hCG beta (CGB3) Mouse Monoclonal Antibody [Clone ID: H6]

Specifications

Product Data
Clone Name	H6
Applications	ELISA, IHC
Recommend Dilution	Immunohistochemistry on Frozen Sections: Does not react on routinely processed frozen sections. Immunohistochemistry on Paraffin Sections: 2 µg/ml (1/200). Proteinase K pretreatment for antigen retrieval is recommended. It works also in ELISA. Suggested Positive Control: Human placenta.
Reactivity	Human
Host	Mouse
Clonality	Monoclonal
Specificity	This Monoclonal antibody Clone h6 recognizes β-HCG, a well defined oncofetal protein of 36.7 kDa m.w. associated with pregnancy and some cancers. Raised serum levels for HCG are found in teratogenic carcinomas and trophoblastic tumors and occasionally in gastrointestinal, urogenital, bronchial or mammary carcinomas, and in lymphomas.
Formulation	PBS, pH 7.2 with 10 mg/ml BSA as a stabilizer and 0.01% Thimerosal as a preservative State: Purified State: Lyophilized purified Ig fraction
Reconstitution Method	Restore with 0.5 ml distilled water.
Concentration	0.4 mg/ml (after reconstitution)
Purification	Affinity Chromatography
Conjugation	Unconjugated
Storage Condition	Prior to reconstitution store at 2-8°C. Following reconstitution store undiluted at 2-8°C for one month or (in aliquots) at -20°C for longer. Avoid repeated freezing and thawing.
Gene Name	chorionic gonadotropin beta subunit 3
Database Link	Entrez Gene 1082 Human UniProt ID P0DN86
Background	Human gonadothropin is a glycoprotein of 36.7kDa consisting of two subunits. The α-chain (MW 14.5 kD) is common to three other glycoprotein hormones (TSH, FSH, LH) whereas the β-chain (22.2kD) is more different. The β-chain of HCG and LH (lutrophin) have sequence homology in the first 112 amino acids and differ at the C-terminal end consisting of 24 amino acids.
Synonyms	Choriogonadotropin subunit beta, CGB, CGB3, beta hCG, hCG-beta
