活性GLP-1(7-36)特異性酶免試劑盒
美國*
【型號】KT-871
【預期用途】
該高靈敏度ELISA(酶聯(lián)免疫吸附測定)試劑盒是專門用來定量檢測血清樣本中的胰高血糖素樣肽-1(7-36)[GLP-1(7-36)]的濃度。哺乳動物中的GLP-1肽鏈的基本氨基酸序列*相同,如:小鼠、大鼠、豬、狗、猴、人等。該試劑盒僅適用于科學研究。
【實驗原理】
這個ELISA的設計,研發(fā)和生產(chǎn)的目的是對血漿樣品中的活性GLP-1(7-36)進行定量檢測。該試劑盒是基于運用兩個GLP-1(7-36)特異性抗體分別與兩個位點結合的“雙位點夾心”技術。
將標準品、質控品、和待測樣品加入鏈霉親和素包被的微孔板中。隨后,將生物素偶聯(lián)的的GLP-1(7-36)特異抗體和HRP標記的GLP-1(7-36)特異抗體混合物添加到各個孔中。經(jīng)過*個保溫孵育期后,形成了“鏈霉親和素-生物素抗體- GLP-1(7-36)-HRP標記抗體”的“雙位點夾心”結構,該復合體被微孔板的內(nèi)壁吸附住。游離的HRP標記抗體和緩沖基質則在洗滌過程中被沖走。微孔板加入過氧化物酶基質(3,3',5,5'-四甲基聯(lián)苯胺,TMB)并經(jīng)過一段時間的反應后,用酶標儀測量吸光度。微孔板內(nèi)壁的免疫復合體的酶活性與樣本中的GLP-1(7-36)濃度成正比。

Active GLP-1 (7-36) Specific ELISA Kit
Catalog Number: KT-871
INTENDED USE
This high sensitive ELISA (enzyme-linked immunosorbent assay) kit is produced for the exclusively quantitative determination of bioactive glucagon-like peptide-1 (7-36) [GLP-1 (7-36)] level in plasma samples. The primary amino acid sequence of GLP-1 peptide is identical among mammalian species, i.e. rat, mouse, pig, human, etc. This kit is for research purpose only.
ASSAY PRINCIPLE
This ELISA is designed, developed and produced for the quantitative measurement of bioactive GLP-1 (7-36) in plasma sample. The assay utilizes the two-site “sandwich” technique with two selected GLP-1 (7-36) specific antibodies.
Assay standards, controls and test samples are directly added to wells of a microplate that is coated with streptavidin. Subsequently, a mixture of biotinylated GLP-1 (7-36) specific antibody and a horseradish peroxidate (HRP) conjugated GLP-1 (7-36) specific antibody is added to each well. After the first incubation period, a “sandwich” immunocomplex of “Streptavidin – Biotin-Antibody – GLP-1(7-36) – HRP conjugated antibody” is formed and attached to the wall of the plate. The unbound HRP conjugated antibody is removed in a subsequent washing step. For the detection of this immunocomplex, each well is then incubated with a substrate solution in a timed reaction and then measured in a spectrophotometric microplate reader. The enzymatic activity of the immunocomplex bound to GLP-1 (7-36) on the wall of the microtiter well is directly proportional to the amount of GLP-1 (7-36) in the sample.
