Native Proteins and Derivatives
ATCC NCI-H23; Lung Adenocarcinoma; Human (Homo sapiens)
NCI-H23 [H23] is an epithelial-like cell that was isolated from the lung of a Black, 51-year-old, male patient with adenocarcinoma. This cell line was deposited by AF Gazdar and JD Minna and can be used in toxicology and cancer research.
ILEX LIFE SCIENCES LLC BOVINE THROMBIN PROTEIN 10 KU
Ilex Life Sciences Thrombin Bovine, Purified Protein (10,000 U). DESCRIPTION: Thrombin Bovine, purified native enzyme, lyophilized. CAS REGISTRY NO.: 9002-04-4. BIOLOGICAL ACTIVITY: 164 US units/mg protein (may vary with each lot number, please refer to enclosed datasheet). FORMULATION: Sterile filtered beige lyophilized powder; formulated with glycine, CaCl2 and sodium chloride, PH 6.8. APPLICATION: As a result of its high proteolytic specificity, thrombin has become an important biochemical protein. The thrombin cleavage site (Leu-Val-Pro-Arg-Gly-Ser) is widely used in linker regions of recombinant fusion protein constructs. After the purification of the fusion protein, thrombin is used to cleave between the Arginine and Glycine residues of the cleavage site, efficiently removing the purification tag from the protein of interest with a high degree of specificity. SYNONYMS: Activated Factor IIa, Factor 2A, F2, PT, RPRGL2, THPH1, coagulation factor II, EC 3.4.21.5, UniProtKB# P00735.
ILEX LIFE SCIENCES LLC Human Chorionic Gonadotropin (hCG), Native Protein (Urine), Bioactive, 2.5 mg
Our Human Chorionic Gonadotropin (hCG) is a native protein produced from a sterile preparation of placental glucoprotein urine of pregnant women and has a total Mw of 36.7 kDa. The hCG 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. BIOLOGICAL ACTIVITY: Each lot is bioactivity tested and the IU/mg is stated on a lot-specific datasheet and vial label. Generally speaking, 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.

BioVendor, LLC Human Chorionic Gonadotropin (hCG), Native Protein (10 mg)
Human Chorionic Gonadotropin (hCG) Native Protein, 10 mg. Research use only. Bioactivity approx. 5000-6000 IU/mg. Each lot is tested for biological activity which may vary with each lot. Produced from a sterile preparation of placental glucoprotein urine of pregnant women. Total MW of 36,700 Dalton. Consists of 237 amino acids, a chain-92 a.a. and b chain-145 a.a. Sterile filtered white powder, lyophilized w/ no additives. hCG is a peptide hormone used in superovulation techniques to increase the number of ovulated oocytes in lab animals. Mice are typically injected with PMSG to stimulate follicle growth and later injected with hCG to induce ovulation. hCG is made by the embryo soon after conception and later by the syncytiotrophoblast. hCG prevents the disintegration of the corpus luteum and thereby maintains progesterone production, critical for human pregnancy. hCG may affect immune tolerance of the pregnancy. Early pregnancy testing is usually based on hCG detection/measurement.
