cyclicAMP ELISA Kit (OKEH02525)

OKEH02525 96 Wells
EUR 727
Description: Description of target: cAMP is a second messenger, used for intracellular signal transduction, such as transferring into cells the effects of hormones like glucagon and adrenaline, which cannot pass through the cell membrane. It is involved in the activation of protein kinases and regulates the effects of adrenaline and glucagon. cAMP also binds to and regulates the function of ion channels such as the HCN channels and a few other cyclic nucleotide-binding proteins such as Epac1. cAMP is synthesised from ATP by adenylyl cyclase located on the inner side of the plasma membrane. Adenylyl cyclase is activated by a range of signaling molecules through the activation of adenylyl cyclase stimulatory G (Gs)-protein-coupled receptors and inhibited by agonists of adenylyl cyclase inhibitory G (Gi)-protein-coupled receptors. Liver adenylyl cyclase responds more strongly to glucagon, and muscle adenylyl cyclase responds more strongly to adrenaline. cAMP decomposition into AMP is catalyzed by the enzyme phosphodiesterase.;Species reactivity: All;Application: ;Assay info: Assay Methodology: Quantitative Competitive ELISA;Sensitivity: 0.096nmol/L

Cholylglycine ELISA Kit (OKEH02529)

96 Wells
EUR 727
Description: Description of target: erum Cholygllycine (Cholygllycine, CG) is a combination of secondary bile acids with glycine conjugated bile acids, in liver cells, cholesterol, after its complex enzymatic reaction, turn into the primary bile acid. Cholic acid (CA) and chenodeoxycholic acid (the CD-CA). Bile acid steroid nucleus three hydroxyl groups (C3, C7, C12), the side chain hydroxyl at the end of the peptide bond and glycine combined with a molecular weight of 462u. CG normal metabolic pathways of the intestine - liver circulation, CG synthesized by hepatocytes, bile canaliculi, bile duct discharged into the gall bladder, along with the bile into the duodenum to help digestion of food. 95% of bile acid reabsorption in the distal ileum, come back to the liver via the portal vein, and uptake by the liver cells to re-use. Exist in the form of protein binding in serum, the total amount of overflow into the systemic circulation is less than 1%. Under normal circumstances, bile acid content in the peripheral blood, leaving little room for normal adults, whether fasting or postprandial serum CG concentration stabilized at a low level. When liver cells are damaged, the liver cell uptake CG capacity decreased, resulting in increased CG content in the blood; cholestasis, liver excretion of bile acids that barriers to reflux of blood circulation increased CG content, but also to the blood CG levels increased. Therefore, the determination of serum glycocholic acid (SCG) by ELISA method is a sensitive indicator to evaluate the function of liver cells and their hepatobiliary material circulation. Normal serum Cholygllycine: 1.3 ± 0.8mg / L, range 0.4 to 2.98mg / L, and the low limit of the hepatitis diagnosis <3.18mg / L ;Species reactivity: All;Application: ;Assay info: Assay Methodology: Quantitative Competitive ELISA;Sensitivity: 0.5 ng/mL

DHEA ELISA Kit (OKEH02530)

96 Wells
EUR 662
Description: Description of target: 5-Dehydroepiandrosterone (5-DHEA) is a 19-carbon endogenous steroid hormone. It is the major secretory steroidal product of the adrenal glands and is also produced by the gonads and the brain. DHEA is the most abundant circulating steroid in humans. DHEA has been implicated in a broad range of biological effects in humans and other mammals. It acts on the androgen receptor both directly and through its metabolites, which include androstenediol and androstenedione, which can undergo further conversion to produce the androgen testosterone and the estrogens, including estrone, estradiol, and estriol. DHEA is also a potent sigma-1 agonist. It is considered a neurosteroid. ;Species reactivity: All;Application: ;Assay info: Assay Methodology: Quantitative Competitive ELISA;Sensitivity: 0.091 ng/mL

Dihydrotestosterone ELISA Kit (OKEH02531)

96 Wells
EUR 727
Description: Description of target: Dihydrotestosterone (5alpha-Dihydrotestosterone, commonly abbreviated to DHT) is an androgen or male sex hormone. The enzyme 5alpha-reductase synthesises DHT in the prostate, testes, hair follicles, and adrenal glands. This enzyme reduces the 4,5 double-bond of the hormone testosterone. ;Species reactivity: All;Application: ;Assay info: Assay Methodology: Quantitative Competitive ELISA;Sensitivity: 0.058 ng/mL

Thyroxine ELISA Kit (OKEH02532)

96 Wells
EUR 361
Description: Description of target: Thyroxine, or 3,5,3',5'-tetraiodothyronine (often abbreviated as T4), a form of thyroid hormones, is the major hormone secreted by the follicular cells of the thyroid gland. Thyroxine is synthesized via the iodination and covalent bonding of the phenyl portions of tyrosine residues found in an initial peptide, thyroglobulin, which is secreted into thyroid granules. These iodinated diphenyl compounds are cleaved from their peptide backbone upon being stimulated by thyroid-stimulating hormone.;Species reactivity: All;Application: ;Assay info: Assay Methodology: Quantitative Competitive ELISA;Sensitivity: 0.0975 ng/mL

Triiodothyronine ELISA Kit (OKEH02533)

96 Wells
EUR 492
Description: Description of target: The L-triiodothyronine (T3, liothyronine) thyroid hormone is normally synthesized and secreted by the thyroid gland in much smaller quantities than L-tetraiodothyronine (T4, levothyroxine, L-thyroxine). Most T3 is derived from peripheral monodeiodination of T4 at the 5 position of the outer ring of the iodothyronine nucleus. The hormone finally delivered and used by the tissues is mainly T3.;Species reactivity: All;Application: ;Assay info: Assay Methodology: Quantitative Competitive ELISA;Sensitivity: 35 pg/mL

Estriol ELISA Kit (OKEH02535)

96 Wells
EUR 727
Description: Description of target: Estriol (also oestriol) is one of the three main estrogens produced by the human body. Estriol (E3) is only produced in significant amounts during pregnancy as it is made by the placenta from 16-Hydroxydehydroepiandrosterone sulfate (16-OH DHEAS), an androgen steroid made in the fetal liver and adrenal glands. The human placenta produces pregnenolone and progesterone from circulating cholesterol. Pregnenolone is converted in the fetal adrenal gland into dehydroepiandrosterone (DHEA), a C19 steroid, then subsequently sulfonated to dehydroepiandrosterone sulfate (DHEAS). DHEAS is converted to 16-OH DHEAS in the fetal liver. The placenta converts 16-OH DHEAS to estriol, and is the predominant site of estriol synthesis.;Species reactivity: All;Application: ;Assay info: Assay Methodology: Quantitative Competitive ELISA;Sensitivity: 1.34 ng/mL

Androstenedione ELISA Kit (OKEH02536)

96 Wells
EUR 727
Description: Description of target: Androstenedione (also known as 4-androstenedione and 17-ketoestosterone) is a 19-carbon steroid hormone produced in the adrenal glands and the gonads as an intermediate step in the biochemical pathway that produces the androgen testosterone and the estrogens estrone and estradiol. Androstenedione is the common precursor of male and female sex hormones. Some androstenedione is also secreted into the plasma, and may be converted in peripheral tissues to testosterone and estrogens. ;Species reactivity: All;Application: ;Assay info: Assay Methodology: Quantitative Competitive ELISA;Sensitivity: 0.078 ng/mL
