St John's Laboratory 是一家成立于2013年的英國生物科技公司，總部位于倫敦，專注于抗體試劑、試劑盒及相關(guān)生物試劑的研發(fā)與生產(chǎn)。公司以技術(shù)創(chuàng)新和數(shù)據(jù)驅(qū)動為核心發(fā)展理念，致力于為全球科研、醫(yī)療及工業(yè)客戶提供高精度、高穩(wěn)定性的實(shí)驗(yàn)工具。
作為早期推動抗體驗(yàn)證計劃（Antibody Validation Project, AVP）的企業(yè)之一，St John's Laboratory通過建立去中心化的質(zhì)量標(biāo)準(zhǔn)體系，與全球科研用戶共同制定驗(yàn)證標(biāo)準(zhǔn)，顯著提升了產(chǎn)品的透明度和可靠性。其AVP項(xiàng)目不僅獲得《自然》雜志的認(rèn)可，還通過用戶共享驗(yàn)證數(shù)據(jù)，形成全球科研社區(qū)的知識共享網(wǎng)絡(luò)。
公司堅持“少而精"的產(chǎn)品策略，早期聚焦抗體試劑單一品類，嚴(yán)格把控質(zhì)量，逐步擴(kuò)展至免疫組化（IHC）和體外診斷（IVD）領(lǐng)域。截至2024年，其產(chǎn)品線已覆蓋科研用抗體、ELISA試劑盒、蛋白質(zhì)分析工具等，廣泛應(yīng)用于癌癥研究、神經(jīng)科學(xué)、傳染病檢測等方向。
St John's Laboratory注重用戶體驗(yàn)，設(shè)計以簡潔高效為原則，提供精準(zhǔn)搜索功能與在線客服支持，同時采用黑色主色調(diào)保護(hù)用戶視力。此外，公司通過原生內(nèi)容SEO策略積累了大量抗體驗(yàn)證數(shù)據(jù)，提升產(chǎn)品在搜索引擎的可見性。

簡短描述：本15d-PGJ2競爭性ELISA是一種體外酶聯(lián)免疫吸附試驗(yàn)，用于檢測所有血清、血漿及其他生物流體中的樣本。
背景：本ELISA試劑盒采用競爭性酶聯(lián)免疫吸附試驗(yàn)（ELISA）原理。本試劑盒提供的微量酶標(biāo)板已預(yù)先包被15d-PGJ2。反應(yīng)過程中，樣本或標(biāo)準(zhǔn)品中的15d-PGJ2與固相載體上固定量的15d-PGJ2競爭結(jié)合針對15d-PGJ2的生物素標(biāo)記檢測抗體的結(jié)合位點(diǎn)。過量的結(jié)合物及未結(jié)合的樣本或標(biāo)準(zhǔn)品從酶標(biāo)板上洗去，隨后向每個微孔中加入抗生物素蛋白-辣根過氧化物酶（HRP）偶聯(lián)物并孵育。隨后向每個孔中加入TMB底物溶液。通過加入終止液終止酶-底物反應(yīng)，并在450 nm±2 nm波長下通過分光光度法測定顏色變化。通過與標(biāo)準(zhǔn)曲線比較樣品的光密度值（OD），即可測定樣品中15d-PGJ2的濃度。
宿主細(xì)胞：CHO細(xì)胞
注：僅限進(jìn)一步研究使用（RUO）。嚴(yán)禁用于診斷或治療用途。
簡短描述：重組人4-1BB（CD137）蛋白由CHO細(xì)胞開發(fā)，適用于研究應(yīng)用。
組織特異性 ：在活化的T細(xì)胞表面表達(dá)。
功能 ：TNFSF9/4-1BBL的受體。傳遞一種信號，可增強(qiáng)CD8(+) T細(xì)胞的存活能力、細(xì)胞毒性和線粒體活性，從而促進(jìn)抗病毒及抗腫瘤免疫（可能）。
蛋白名稱 ：腫瘤壞死因子受體超家族成員9 、4-1bb配體受體 、Cdw137 、T細(xì)胞抗原4-1bb同源物 、T細(xì)胞抗原Ila 、CD抗原Cd137
細(xì)胞定位 ：細(xì)胞膜
蛋白胨是一種噴霧干燥粉末，通過動物組織的可控酶解制成。酶包括胃蛋白酶、木瓜蛋白酶和胰酶（后者含胰蛋白酶）。
胃蛋白酶會在含有苯丙氨酸或亮氨酸鍵的任意位置切割肽鏈。
木瓜蛋白酶會在鄰近精氨酸、賴氨酸、苯丙氨酸和甘氨酸的位置切割肽鏈；胰酶則在精氨酸、賴氨酸、酪氨酸、色氨酸、苯丙氨酸和亮氨酸鍵處發(fā)揮作用。
通過水解組織可制得稻草色的蛋白胨，其營養(yǎng)豐富且易溶于水。蛋白胨含有肽類、游離氨基酸和生長因子的混合物。
由于氯化鈉濃度較低，F(xiàn)ormedium™蛋白胨非常適合酵母細(xì)胞培養(yǎng)。
室溫下干燥儲存。
組織特異性 ：在骨中高度表達(dá)。在關(guān)節(jié)軟骨和軟骨細(xì)胞中大量表達(dá)，且在骨關(guān)節(jié)炎（OA）中表達(dá)升高。在關(guān)節(jié)軟骨OA病變的軟骨細(xì)胞中與ASPN共定位。
翻譯后修飾 ：轉(zhuǎn)化生長因子β1前體蛋白：該前體蛋白在高爾基體內(nèi)被弗林蛋白酶（FURIN）切割，形成轉(zhuǎn)化生長因子β1（TGF-β-1）和潛伏相關(guān)肽（LAP）鏈，二者通過非共價鍵連接，使TGF-β-1處于失活狀態(tài)。潛伏相關(guān)肽：經(jīng)N-糖基化修飾。去糖基化可激活轉(zhuǎn)化生長因子β1（TGF-β-1）。然而，觸發(fā)TGF-β-1去糖基化激活的機(jī)制尚不清楚。
功能 ：轉(zhuǎn)化生長因子β1前體蛋白：是潛伏相關(guān)肽（LAP）和轉(zhuǎn)化生長因子β1（TGF-β-1）鏈的前體，二者分別構(gòu)成TGF-β-1的調(diào)節(jié)亞基和活性亞基。潛伏相關(guān)肽：在TGF-β-1儲存于細(xì)胞外基質(zhì)期間，維持其活性亞基處于潛伏狀態(tài)。通過與TGF-β-1非共價結(jié)合，并與LTBP1、LRRC32/GARP和LRRC33/NRROS等“微環(huán)境分子"相互作用調(diào)控其激活（這些分子控制TGF-β-1的激活）。與LRRC33/NRROS的相互作用可能調(diào)控巨噬細(xì)胞和小膠質(zhì)細(xì)胞中TGF-β-1的激活。與LRRC32/GARP的相互作用控制活化調(diào)節(jié)性T細(xì)胞（Tregs）表面TGF-β-1的激活。與整合素（ITGAV:ITGB6或ITGAV:ITGB8）結(jié)合會導(dǎo)致潛伏相關(guān)肽鏈構(gòu)象改變，進(jìn)而釋放活性TGF-β-1。
轉(zhuǎn)化生長因子β1：一種多功能蛋白，調(diào)控多種細(xì)胞類型的生長與分化，并參與正常發(fā)育、免疫功能、小膠質(zhì)細(xì)胞功能及神經(jīng)退行性疾病應(yīng)答等多種過程。其激活為成熟形式需經(jīng)歷多個步驟：前體蛋白在高爾基體內(nèi)切割后，潛伏相關(guān)肽（LAP）和轉(zhuǎn)化生長因子β1（TGF-β-1）鏈仍通過非共價鍵連接，使TGF-β-1在儲存于細(xì)胞外基質(zhì)期間保持失活狀態(tài)。同時，LAP鏈與LTBP1、LRRC32/GARP和LRRC33/NRROS等“微環(huán)境分子"相互作用，這些分子控制TGF-β-1的激活并使其在細(xì)胞外環(huán)境中儲存時維持潛伏狀態(tài)。TGF-β-1通過整合素（ITGAV:ITGB6或ITGAV:ITGB8）從LAP上釋放：整合素與LAP結(jié)合可穩(wěn)定LAP“蝴蝶結(jié)尾"結(jié)構(gòu)的另一種構(gòu)象，導(dǎo)致LAP鏈構(gòu)象改變并釋放活性TGF-β-1。釋放LAP后激活的TGF-β-1通過與TGF-β受體（TGFBR1和TGFBR2）結(jié)合發(fā)揮作用（受體介導(dǎo)信號轉(zhuǎn)導(dǎo)）。盡管多種細(xì)胞類型均可表達(dá)TGF-β-1，但其活性僅局限于細(xì)胞微環(huán)境內(nèi)，這得益于LAP鏈和“微環(huán)境分子"對其激活的精細(xì)調(diào)控。在骨重塑中起重要作用：作為成骨細(xì)胞骨形成的強(qiáng)效刺激因子，可誘導(dǎo)定向成骨細(xì)胞的趨化、增殖和分化。其濃度依賴性可促進(jìn)輔助性T細(xì)胞17（Th17）或調(diào)節(jié)性T細(xì)胞（Treg）譜系分化：高濃度時，通過FOXP3介導(dǎo)抑制RORC并下調(diào)IL-17表達(dá)，促進(jìn)Treg細(xì)胞發(fā)育；低濃度時，與IL-6和IL-21協(xié)同作用，誘導(dǎo)IL-17和IL-23受體表達(dá)，促進(jìn)向Th17細(xì)胞分化。通過調(diào)控性膜內(nèi)蛋白水解（RIP）激活CREB3L1，刺激膠原蛋白持續(xù)產(chǎn)生。通過誘導(dǎo)SMAD2/3磷酸化并隨后轉(zhuǎn)位至細(xì)胞核，介導(dǎo)SMAD2/3激活。通過促進(jìn)IPO7介導(dǎo)的磷酸化SMAD2核轉(zhuǎn)位及后續(xù)靶基因轉(zhuǎn)錄，正向調(diào)控牙乳頭細(xì)胞中的成牙本質(zhì)細(xì)胞分化。可在多種細(xì)胞類型中誘導(dǎo)上皮間質(zhì)轉(zhuǎn)化（EMT）和細(xì)胞遷移。
