产品概述
Human Angiogenin ELISA Kit (ab219629) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of Angiogenin protein in cell culture extracts, cell culture supernatant, cit plasma, edta plasma, hep plasma, serum, and cell culture media. It uses our proprietary SimpleStep ELISA® technology. Quantitate Human Angiogenin with 1.06 pg/ml sensitivity.
SimpleStep ELISA® technology employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details. Our SimpleStep ELISA® technology provides several benefits:
- Single-wash protocol reduces assay time to 90 minutes or less
- High sensitivity, specificity and reproducibility from superior antibodies
- Fully validated in biological samples
- 96-wells plate breakable into 12 x 8 wells strips
A 384-well SimpleStep ELISA® microplate (ab203359) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.

说明
Angiogenin is a member of the ribonuclease superfamily with approximately 35% amino acid sequence homology with pancreatic RNase. Angiogenin can act to inhibit protein synthesis by functioning as a cytotoxic tRNA-specific RNase.
Cells expressing Angiogenin include vascular endothelial and smooth muscle cells, fibroblasts, colonic epithelium, peripheral blood lymphocytes, lung cell lines, and primary gastrointestinal adenocarcinomas. Basal levels of Angiogenin are also present in normal human serum and plasma. Angiogenin has been reported to serve as protection for motor neurons and it follows that Angiogenin is associated with neurological diseases, specifically, mutations to this gene are linked to Amyotrophic Lateral Sclerosis (ALS). Human and mouse Angiogenin share 74% homology in amino acid sequence.

功能
May function as a tRNA-specific ribonuclease that abolishes protein synthesis by specifically hydrolyzing cellular tRNAs. Binds to actin on the surface of endothelial cells; once bound, angiogenin is endocytosed and translocated to the nucleus. Angiogenin induces vascularization of normal and malignant tissues. Angiogenic activity is regulated by interaction with RNH1 in vivo. -
组织特异性
Expressed predominantly in the liver. Also detected in endothelial cells and spinal cord neurons. -
疾病相关
Defects in ANG are the cause of susceptibility to amyotrophic lateral sclerosis type 9 (ALS9) [MIM:611895]. ALS is a degenerative disorder of motor neurons in the cortex, brain stem and spinal cord. ALS is characterized by muscular weakness and atrophy. -
序列相似性
Belongs to the pancreatic ribonuclease family. -
发展阶段
Low level expression in the developing fetus, increased in the neonate, and maximal in the adult. -

SimpleStep ELISA technology allows the formation of the antibody-antigen complex in one single step, reducing assay time to 90 minutes. Add samples or standards and antibody mix to wells all at once, incubate, wash, and add your final substrate. See protocol for a detailed step-by-step guide.

The concentrations of Angiogenin were measured in duplicates, interpolated from the Angiogenin standard curves and corrected for sample dilution. Undiluted samples are as follows: serum 1:1,000, plasma (citrate) 1:1,000, plasma (EDTA) 1:1,000, and plasma (heparin) 1:1,000. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean Angiogenin concentration was determined to be 342.53 ng/mL in neat serum, 310.16 ng/mL in neat plasma (citrate), 249.90 ng/mL in neat plasma (EDTA), and 329.36 ng/mL in neat plasma (heparin).

The concentrations of Angiogenin were measured in duplicates, interpolated from the Angiogenin standard curves and corrected for sample dilution. Undiluted samples are as follows: RPMI culture media 50% and HepG2 supernatant 25%. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean Angiogenin concentration was determined to be 527.60 pg/mL in neat, spiked RPMI culture media. The mean Angiogenin concentration was determined to be 945.93 pg/mL in neat, native HepG2 supernatant.
