膠原蛋白雜交肽是3-Hisperson Inc.的產(chǎn)品。膠原蛋白雜交肽(CHP)是一種新型獨(dú)特的肽,可在體外和體內(nèi)特異性結(jié)合未折疊的膠原蛋白鏈[1 2 3]。通過共享天然膠原蛋白的Gly-X-Y重復(fù)序列,CHP具有通過以類似于退火至互補(bǔ)DNA鏈的DNA片段的方式重新形成三螺旋結(jié)構(gòu)而與變性膠原蛋白鏈雜交的強(qiáng)能力。CHP非常具體:由于缺乏結(jié)合位點(diǎn),它對(duì)完整的膠原蛋白分子具有可忽略的親和力,并且由于其中性和親水性,它對(duì)非特異性結(jié)合是惰性的。CHP是一種強(qiáng)大的組織病理學(xué)工具,能夠直接檢測(cè)由多種疾病引起的炎癥和組織損傷以及發(fā)育和衰老期間的組織重塑[3]。CHP可在不使用合成熒光基質(zhì)或遺傳修飾細(xì)胞的情況下,在3D膠原蛋白培養(yǎng)物中通過癌細(xì)胞的蛋白水解遷移而穩(wěn)健地可視化細(xì)胞周基質(zhì)周轉(zhuǎn)[4]。CHP可以在分子水平上測(cè)量和定位膠原組織的機(jī)械損傷[5]。它還能夠評(píng)估脫細(xì)胞細(xì)胞外基質(zhì)中的膠原蛋白變性[6]。此外,CHP可用于在SDS-PAGE凝膠中特異性地顯示膠原蛋白條帶,而不需要蛋白質(zhì)印跡[7]。(目錄號(hào):BIO)用于抗生物素蛋白/鏈霉抗生物素蛋白介導(dǎo)的方法,包括HRP-酶法5-FAM(目錄號(hào):FLU),用于綠色熒光檢測(cè)和Cy 3(Catalog #:RED)用于紅色熒光檢測(cè)。應(yīng)用:免疫熒光免疫組化SDS-PAGE(凝膠內(nèi)蛋白質(zhì)印跡)運(yùn)輸條件室溫下以粉末形式快速運(yùn)輸。儲(chǔ)存-20 ° C作為粉末; 4 °C在水中重構(gòu)后無需等分和冷凍。參考文獻(xiàn)1)"Targeting and mimicking collagens via triple helical peptide hybridization“ Curr Opin Chem Biol 2013 17 968- 975. 2)”Targeting collagen strand by photo-triggered triple-helix hybridization“Proceedings of the National Academy of Sciences of the United States of America 2012 109 14767-14772.?DOI:10.1073/pnas.1209721109.3)“用膠原雜交肽進(jìn)行組織重塑的原位成像。ACS Nano 2017 11 9825。DOI:10.1021/acsnano.7b031504)“通過肽雜交可視化膠原蛋白水解:從3D細(xì)胞培養(yǎng)到體內(nèi)成像。“Biomaterials 2018 DOI:10.1016/j.biomerials.2018.08.0395)“膠原雜交肽實(shí)現(xiàn)膠原中機(jī)械損傷的分子水平檢測(cè)和定位。《國(guó)家通訊》 2017 8 14913 DOI:10.1038/ncomms14913.6)“使用膠原雜交肽對(duì)脫細(xì)胞組織中的膠原變性進(jìn)行分子評(píng)估。生物材料學(xué)報(bào) 2017. 53 268-278 DOI:10.1016/j.actbio.2017.01.0797)“Direct detection of collagenous proteins by fluorescently labeled collagen mimetic peptides” Bioconjugate Chemistry 2013 24 9-16.

產(chǎn)品描述
The Collagen Hybridizing Peptides are products of 3-Helix Inc.The collagen hybridizing peptide (CHP) is a novel and unique peptide that specifically binds unfolded collagen chains both in vitro and in vivo [1 2 3]. By sharing the Gly-X-Y repeating sequence of natural collagen CHP has a strong capability to hybridize with denatured collagen chains by reforming the triple helical structure in a fashion similar to DNA fragments annealing to complementary DNA strands. CHP is extremely specific: it has negligible affinity to intact collagen molecules due to lack of binding sites and it is inert towards non-specific binding because of its neutral and hydrophilic nature.CHP is a powerful histopathology tool which enables straightforward detection of inflammation and tissue damage caused by a large variety of diseases as well as tissue remodeling during development and aging [3]. CHP robustly visualizes the pericellular matrix turnover caused by proteolytic migration of cancer cells within 3D collagen culture without the use of synthetic fluorogenic matrices or genetically modified cells [4]. CHP can measure and localize mechanical injury to collagenous tissue at the molecular level [5]. It also enables assessment of collagen denaturation in decellularized extracellular matrix [6]. In addition CHP can be used to specifically visualize collagen bands in SDS-PAGE gels without the need for western blot [7].CHP come in three varieties: labeled with biotin (Catalog #: BIO) for avidin/streptavidin-mediated including HRP-enzyme methods 5-FAM (Catalog #: FLU) for green fluorescence detection and Cy3 (Catalog #: RED) for red fluorescence detection.Applications: immunofluorescence immunohistochemistry SDS-PAGE (in-gel Western blot)Shipping ConditionsExpress shipping as powder at ambient temperature.
