Exalpha 凋亡增殖、炎癥、免疫學(xué)傳染病學(xué)和細(xì)胞間結(jié)構(gòu)研究
Exalpha公司簡介
Exalpha有限公司于2000年在馬薩諸塞州雪莉(美國)成立。該公司主要通過開發(fā)和生產(chǎn)抗體來支持生命科學(xué)領(lǐng)域的研究人員和科學(xué)家。
Exalpha公司產(chǎn)品領(lǐng)域
Exalpha公司其領(lǐng)域涉及信號通路、凋亡、增殖、炎癥、免疫學(xué)、傳染病學(xué)和細(xì)胞間結(jié)構(gòu)研究等方面。Exalpha主要產(chǎn)品線包括Proliferation&apoptosis, Enzymes&Proteins, Clinical IHC Markers , GPCRs等多個產(chǎn)品線,可提供給全球的科研實(shí)驗(yàn)室,制藥企業(yè),生物技術(shù)和診斷公司,醫(yī)院等,目前旗下的代理公司遍布全球。
細(xì)胞增殖是生物體的重要生命特征,是生物體生長、發(fā)育、繁殖以及遺傳的基礎(chǔ)。監(jiān)測細(xì)胞群的生長對細(xì)胞的狀態(tài)研究很有必要??蒲泄ぷ髡邆兘?jīng)常需要檢測細(xì)胞增殖情況,比如驗(yàn)證抗腫瘤藥物的藥效時,監(jiān)測細(xì)胞增殖及存活情況;研究腫瘤侵襲與轉(zhuǎn)移模型時,分析細(xì)胞轉(zhuǎn)移或侵襲的路徑;分析創(chuàng)傷的修復(fù)或組織的重建時,檢測細(xì)胞生長情況等等。檢測細(xì)胞增殖及活性變化則可以很好的反映細(xì)胞的生長狀況。
細(xì)胞增殖的研究方法
細(xì)胞增殖的研究方法有很多種,根據(jù)檢測原理不同,主要分為DNA合成檢測法、代謝活性檢測法、細(xì)胞增殖標(biāo)志物檢測法等。本文重點(diǎn)介紹DNA合成檢測之Brdu檢測法,傳統(tǒng)DNA合成檢測方法使用胸腺嘧啶核苷(3H-TdR)摻入DNA,然后通過放射自顯影或閃爍計(jì)數(shù)對DNA進(jìn)行定量,該方法由于存在放射性物質(zhì)、實(shí)驗(yàn)周期長、操作繁瑣,且需要昂貴的設(shè)備,目前已被BrdU(5-Bromo-2-deoxyuridine,5-溴脫氧尿嘧啶核苷)檢測方法取代,BrdU作為一種胸苷類似物,可選擇性地?fù)饺朐鲋臣?xì)胞的DNA中,而且可穩(wěn)定存在,并帶到子代細(xì)胞中,細(xì)胞經(jīng)過固定和變性處理后,可用免疫學(xué)方法檢測DNA中BrdU的含量,從而判斷細(xì)胞的增殖能力。
Exalpha Biologicals品牌BrdU檢測試劑盒
因組織細(xì)胞內(nèi)無內(nèi)源性BrdU存在,可利用BrdU相關(guān)抗體來檢測和定位摻入活躍增殖細(xì)胞新合成DNA的BrdU,Exalpha Biologicals 品牌BrdU檢測試劑盒的優(yōu)勢在于使用細(xì)胞層作為固相,將BrdU試劑摻入微孔板中的細(xì)胞,除了對細(xì)胞增殖情況進(jìn)行評估外,還可以從單個培養(yǎng)物中分析細(xì)胞數(shù)量、形態(tài)和細(xì)胞抗原等信息。同時Exalpha Biologicals 品牌BrdU檢測試劑盒可通過試劑盒自帶的固定/變性溶液一步完成細(xì)胞固定、透化和DNA變性等實(shí)驗(yàn)流程,大大縮短了實(shí)驗(yàn)時間。Exalpha Biologicals 品牌BrdU檢測試劑盒中包含檢測細(xì)胞增殖活性所需的所有組分、操作簡便、無放射性、廣泛的樣本適用性,已得到眾多科研工作者的青睞。
