Ilex Life Sciences Human Chorionic Gonadotropin (hCG) Native Protein (Urine) Bioactive 10 mg Our hCG is produced from a sterile preparation of placental glucoprotein urine of pregnant women It has total Mw of 36 7 kDa and consists of 237 amino acids 92 a a a-chain and 145 a a b-chain Lyophilized with no additives Free of HbsAg and antibodies to HIV and HCV Bioactivity Each lot is tested and the IU/mg is stated on a lot-specific datasheet Generally bioactivity ranges between 4000-6000 IU/mg Application Our hCG is commonly used in combination with our Pregnant Mare Serum Gonadotropin (PMSG eCG) in superovulation protocols for production of genetically modified laboratory animals such as GEMM by pronuclear microinjection (transgenic mouse) targeted mutations through CRISPR-Cas9 methods and ES-cell-based gene targeting to produce knockout mice Our hCG can be used in the generation of Xenopus laevis and X tropicalis eggs or embryos for use in experimental models
