Hydroxyproline Colorimetric Assay Kit 羥脯氨酸呈色分析套組

K555-100 羥脯氨酸分析試劑組 Hydroxyproline Colorimetric Assay Kit

http://www.biovision.com/hydroxyproline-colorimetric-assay-kit-4386.html

主要用來測定組織蛋白質/多肽水解物中的脯氨酸, 亦可用再測定其他生物樣品,如血清尿液中的羥脯氨酸含量.

 羥脯氨酸是膠原蛋白的組成成分,占其氨基酸總量的13%,膠原蛋白是構成結締組織的主要成分,也是人體內含量最多的蛋白質,當體內結締組織較大量增生或破壞時,如嚴重骨折、燒傷、重癥肺結核和肝硬變、Hodgkin’s病、甲狀腺功能亢進、羥脯氨酸血癥均可造成血、尿中羥脯氨酸含量的增加。


Kit Summary:
• Detection method- Absorbance (560 nm)
• Sample type- Cell and Tissue  culture supernatants, urine, plasma and serum, as well as many other biological fluids
• Species reactivity- Mammalian
• Applications-  The assay is useful over the range of 0.1-2 μg.

Features & Benefits:
• Simple  procedure; takes less than ~100 minutes
• Convenient and easy to use

Kit components:
• Oxidation Buffer
• Chloramine T Concentrate
• Perchloric acid/Isopropanol Solution
• DMAB Concentrate (in DMSO)
• Hydroxyproline Standard (1 mg/ml)

Description:
Hydroxyproline (4-hydroxyproline) is a common nonproteinogenic amino acid. It is found only in collagen and elastin in mammals but exists in a number of other proteins in plants. Hydroxyproline is formed only as a post-translational modification in the peptide chain and proline hydroxylase does not hydroxylate free proline. Hydroxyproline in tissue hydrolysates is a direct measure of the amount of collagen or gelatin present. A variety of disease states are believed to affect collagen turnover and can cause elevated serum or urine hydroxyproline. Such conditions range from neoplastic, inflammatory, renal or bone disease to endocrine and autoimmune disorders. BioVision’s Hydroxyproline Assay Kit is designed to measure hydroxyproline in tissue or protein/peptide hydrolysates. It can be used to measure hydroxyproline from other biological samples such as serum or urine if they have undergone a prior purification process. It is an easy, convenient method which results in a chromogen with an absorbance maximum at 560 nm. The assay is useful over the range of 0.1-2 μg.

Storage Conditions:
+4°C

BioVision 提供多種生化分析套組 Urea尿素分析套組

BioVision提供多種生化分析套組 (Alanine assay Kit K652-100, Asparaginase Activity Assay Kit K754-100, Aspartate Assay Kit K552-100, Branched Chain Amino Acid(Leu/Ile/Val) Assay Kit K564-100, Glutamate Assay Kit K629-100, Hydroxyproline Assay Kit K555-100, L-Amino Acid Quantitation Kit K639-100, Phenylalanine Assay Kit K572-100)

Urea Assay Kit 尿素分析套組
K375-100

說明:
Urea is a waste product which produced in the liver, dissolved in blood (in a concentration of 2.5
- 7.5 mM), and secreted by the kidneys. Urea also plays a very important role in protein
catabolism, removal of toxic ammonia from the body, and the countercurrent system which
allows for reabsorption of water and critical ions in the nephrons. Urea determination is very
useful for the medical clinician to assess kidney and other organs function of patients.
BioVision’s Urea Assay Kit provides a rapid, simple, sensitive, and reliable for measurement of
Urea level in a variety of samples such as serum, plasma, and urine, etc. In the assay, Urea
reacts as substrate with compounds in the presence of enzymes to form a product that reacts
with the OxiRed probe to generate color (λmax=570nm). The optical density of produced color has
a direct relationship with Urea concentration in the solution. The kit can detect as low as 0.5
nmol per well or 10 μM of Urea. The assay is also suitable for high throughput studies.

測定方式: Absorbance 吸收光 570nm
偵測樣品: Cell and Tissue lysates, culture media, urine, plasma and serum, as well as many other biological fluids
偵測優勢:快速(約一小時),高靈敏度(0.5nmol per well or 10uM of Urea)
