产品概述
Human CD105 ELISA Kit (ab217773) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of CD105 protein in cell culture extracts, cell culture supernatant, cit plasma, edta plasma, hep plasma, serum, and tissue extracts. It uses our proprietary SimpleStep ELISA® technology. Quantitate Human CD105 with 11.1 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
CD105 is a major glycoprotein of vascular endothelium. CD105 is involved in the regulation of angiogenesis. It may play a critical role in the binding of endothelial cells to integrins and/or other RGD receptors. CD105 acts as TGF-beta co-receptor and is involved in the TGF-beta/BMP signaling cascade. It is required for GDF2/BMP9 signaling through SMAD1 in endothelial cells and it modulates TGF-beta1 signaling through SMAD3. CD105 is a homodimer that forms a heteromeric complex with the signaling receptors for transforming growth factor-beta: TGFBR1 and/or TGFBR2. It is able to bind TGF-beta 1, and 3 efficiently and TGF-beta 2 less efficiently. Circulating soluble form of CD105 is elevated in patients with preeclampsia, atherosclerosis and certain cancers including breast, colorectal, and myeloid malignancies.

疾病相关
Defects in ENG are the cause of hereditary hemorrhagic telangiectasia type 1 (HHT1) [MIM:187300, 108010]; also known as Osler-Rendu-Weber syndrome 1 (ORW1). HHT1 is an autosomal dominant multisystemic vascular dysplasia, characterized by recurrent epistaxis, muco-cutaneous telangiectases, gastro-intestinal hemorrhage, and pulmonary (PAVM), cerebral (CAVM) and hepatic arteriovenous malformations; all secondary manifestations of the underlying vascular dysplasia. Although the first symptom of HHT1 in children is generally nose bleed, there is an important clinical heterogeneity. -

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 CD105 were measured in duplicates, interpolated from the CD105 standard curves and corrected for sample dilution. Undiluted samples are as follows: serum 2.225%, plasma (citrate) 2.225%, plasma (heparin) 2.225% and plasma (EDTA) 2.225%. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean CD105 concentration was determined to be 94,646 pg/mL in neat serum, 71,971 pg/mL in neat plasma (citrate), 75,408 pg/mL in neat plasma (heparin), and 76,842 pg/mL in neat plasma (EDTA).

Interpolated concentrations of native CD105 in HUVEC cell extract based on a 40 µg/mL extract load, human placenta tissue extract based on a 90 µg/mL extract load, and human heart tissue extract based on a 60 µg/mL extract load. The concentrations of CD105 were measured in duplicate and interpolated from the CD105 standard curve and corrected for sample dilution. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean CD105 concentration was determined to be 2548 pg/mL in HUVEC cell extract, 542.9 pg/mL in placenta tissue extract, and 528.1 pg/mL in heart tissue extract.

Interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean CD105 concentration was determined to be 61,333 pg/mL with a range of 30,103 – 91,256 pg/mL.

Serum from 10 healthy (not pregnant) female individuals, 5 healthy females in the third trimester of pregnancy (pooled), and 1 individual female in the third trimester showing signs of mild pre-eclampsia were tested for levels of CD105. The concentrations of CD105 were measured from serum in samples in 3 different dilutions in duplicates and interpolated from the CD105 standard curve. The interpolated values are plotted (mean +/- SD, n=3). The mean CD105 concentration was determined to be 61,333 pg/mL in healthy female donor serum, 30,8945 pg/mL in healthy pregnant donor serum, and 703,119 pg/mL in pre-eclampsia patient serum.
