總膠原含量測定試劑盒(無高氯酸鹽)|貨號K406-100 (abcam ab222942)
Total Collagen Assay Kit (Perchlorate-Free) 0.5μg膠原蛋白
膠原蛋白(Collagen )是哺乳動物中含量最豐富的蛋白質,佔體內蛋白質含量的近30%。膠原蛋白是在皮膚(skin),肌腱(tendons),骨( bone),軟骨( cartilage),韌帶( ligaments )和肌肉( muscles)等組織中發現的細胞外支架蛋白(extracellular scaffolding protein )。有超過20種不同的特徵類型的膠原蛋白,但是纖維類型I( fibrilous types I),II( fibrilous types II)和III( fibrilous types III)佔哺乳動物總膠原的90%以上。膠原蛋白具有三螺旋結構(triple helical structure),由三個具有重複Gly-X-Hyp三肽序列的’前原膠原'(preprocollagen) 鏈組成,其中X是任何氨基酸,Hyp是羥脯氨酸(hydroxyproline),翻譯後修飾的氨基酸由脯氨酸 (proline) 通過脯氨酰-4-羥化酶 (prolyl-4- hydroxylase)。在動物中,羥脯氨酸 (hydroxyproline )幾乎全部存在於膠原蛋白(其質量含有大約12-14%的羥脯氨酸)並且有助於其結構剛性和高拉伸強度。羥脯氨酸(Hydroxyproline)因此是組織中存在的膠原量的直接測量指標。據信許多疾病影響膠原蛋白的周轉(collagen turnover),包括腫瘤侵襲(tumor invasion)和轉移(metastasis),類風濕性關節炎(rheumatoid arthritis),心肺纖維化(cardiopulmonary fibrosis )和肌營養不良(muscular dystrophy)。

BioVision的Total Collagen Assay Kit II, K406(Perchlorate-Free, 不含高氯酸鹽)是一種用於檢測各種生物樣品中少量膠原蛋白的快捷方便程序。該測定基於樣品的水解( hydrolysis )以產生游離的Hyp,其被氧化並反應以產生在560nm處具有吸收峰的亮色髮色團。該檢測方法採用專有的酸性顯影液 (acidic developer solution) ,無需使用有害的高氯酸(perchloric acid)即可精確測量水解液中的膠原蛋白,無需任何特殊處理和廢物處理方案。該測定法可以檢測96孔格式中每孔最少0.5μg膠原蛋白,並產生與傳統基於高氯酸的方法實際上相同的比色結果。測試的樣品來源,可以為組織均質液 (Tissue homogenates, i.e. muscle, liver, lung, etc.) 人類或動物生物液體 (biological fluids , serum, urine) 此產品需由儀器進行定量 ELISA儀器設備請按此

產品使用注意事項: 針對樣品水解( hydrolysis )步驟,建議使用聚丙烯樣品瓶可獲得最佳結果 Polypropylene Vials聚丙烯小瓶 (BV Cat. No. M1352) and Screw Caps (BV Cat. No. M1353)。非常堅韌的樣品(含有骨骼或外骨骼組織)在120度C水解步驟,可能需要加熱超過1小時才能完全水解。某些樣品(例如脂肪組織)的水解產物可能含有難以通過離心沉澱的脂質碎片。移取水解樣品以避免將這些不溶性小球轉移到樣品孔中。對於未知樣品,我們建議進行試驗性實驗,以確保讀數在標準曲線範圍內相應地調節樣品水解產物的體積(可以使用2-20μl水解產物)或必要時稀釋水解產物。產品無提供 Clear 96-well plates with flat bottom 、 10N sodium hydroxide (NaOH) 、10N hydrochloric acid (HCl) 、Polypropylene Vials (BV Cat. No. M1352) 、 Screw Caps (BV Cat. No. M1353)
