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(jiǎn)介

Exalpha有限公司于2000年在馬薩諸塞州雪莉（美國(guó)）成立。該公司主要通過(guò)開(kāi)發(fā)和生產(chǎn)抗體來(lái)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(hào)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(gè)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(zhǎng)、發(fā)育、繁殖以及遺傳的基礎(chǔ)。監(jiān)測(cè)細(xì)胞群的生長(zhǎng)對(duì)細(xì)胞的狀態(tài)研究很有必要。科研工作者們經(jīng)常需要檢測(cè)細(xì)胞增殖情況，比如驗(yàn)證抗腫瘤藥物的藥效時(shí)，監(jiān)測(cè)細(xì)胞增殖及存活情況；研究腫瘤侵襲與轉(zhuǎn)移模型時(shí)，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(shí)，檢測(cè)細(xì)胞生長(zhǎng)情況等等。檢測(cè)細(xì)胞增殖及活性變化則可以很好的反映細(xì)胞的生長(zhǎng)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(cè)原理不同，主要分為DNA合成檢測(cè)法、代謝活性檢測(cè)法、細(xì)胞增殖標(biāo)志物檢測(cè)法等。本文重點(diǎn)介紹DNA合成檢測(cè)之Brdu檢測(cè)法，傳統(tǒng)DNA合成檢測(cè)方法使用胸腺嘧啶核苷（3H-TdR）摻入DNA，然后通過(guò)放射自顯影或閃爍計(jì)數(shù)對(duì)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(zhǎng)、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(cè)方法取代，BrdU作為一種胸苷類(lèi)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(guò)固定和變性處理后，可用免疫學(xué)方法檢測(cè)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(cè)試劑盒

因組織細(xì)胞內(nèi)無(wú)內(nèi)源性BrdU存在，可利用BrdU相關(guān)抗體來(lái)檢測(cè)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(cè)試劑盒的優(yōu)勢(shì)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(duì)細(xì)胞增殖情況進(jìn)行評(píng)估外，還可以從單個(gè)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(shí)Exalpha Biologicals 品牌BrdU檢測(cè)試劑盒可通過(guò)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(shí)間。Exalpha Biologicals 品牌BrdU檢測(cè)試劑盒中包含檢測(cè)細(xì)胞增殖活性所需的所有組分、操作簡(jiǎn)便、無(wú)放射性、廣泛的樣本適用性，已得到眾多科研工作者的青睞。
