SBI EXO-FBS-250A-1 無外泌體血清
Exo-FBS Overview: When You're Not Studying Bovine Exosomes
Do you study bovine exosomes? If not, and you use fetal bovine serum (FBS) in your cell or tissue culture media, you may be isolating more bovine exosomes than you realize. Serum is a rich source of exosomes, FBS included. In order to help scientists study only the exosomes they want, SBI provides Exo-FBS™ exosome-depleted FBS.
- Exosome-sized vesicles removed
- Very low levels of CD63 positive cow exosome
- Undetectable levels of cow microRNAs
- Comparable growth rates as standard FBS
- Identical use as standard FBS (add 10% in DMEM or RPMI)
SBI EXO-FBS-250A-1 無外泌體血清
Background
Standard growth media for most cells in culture require FBS as a growth supplement to DMEM. FBS is derived from bovine (cow) serum and contains a high abundance of cow exosome vesicles. These exosomes can interfere or cause significant background issues when studying the exosomes secreted from your cells of interest in standard culture conditions.
SBI has developed an exosome-depleted FBS growth supplement called Exo-FBS that has been stripped of bovine exosomes. Exo-FBS supports equivalent growth of many types of cells in culture, is devoid of cow CD63-positive exosomes, and does not have any measurable bovine microRNAs. Cell growth in Exo-FBS is comparable to standard FBS. The process of manufacturing of Exo-FBS is a patented method in Patent No.: US 9,005,888 B2.
Conclusions
Perform your studies of cellular secreted exosomes in culture without the worry of contaminating cow exosomes in your experiments, and with no ultracentrifugation required when you use ExoQuick-TC. Available as standard FBS supplement or heat inactivated FBS media supplement (treated at 65°C for 15 minutes before bovine exosome removal).

SBI無外泌體血清|SBI*|無外泌體血清說明書介紹:外泌體特指直徑在30-100nm的盤狀囊泡,其內(nèi)部包裹了多種蛋白質(zhì)、mRNA、non-coding RNA等分子。外泌體主要來源于細(xì)胞內(nèi)多囊泡體,經(jīng)多囊泡體外膜與細(xì)胞膜融合后釋放到胞外基質(zhì)中。目前大量文獻(xiàn)報(bào)道,幾乎所有類型的細(xì)胞都可以產(chǎn)生并釋放外泌體,不同的生物體液(血液、尿液、腦脊液、唾液、乳汁、腹水)中都發(fā)現(xiàn)有大量外泌體存在,外泌體由細(xì)胞分泌釋放后,通過個(gè)種體液在體內(nèi)傳播,被靶細(xì)胞攝入后,釋放內(nèi)部的生物分子,參與細(xì)胞間的通訊,調(diào)節(jié)細(xì)胞功能。
對于大多數(shù)細(xì)胞來說,體外培養(yǎng)時(shí)所用的標(biāo)準(zhǔn)培養(yǎng)基都必須在基礎(chǔ)培養(yǎng)基的基礎(chǔ)上外加FBS作為生長添加物。常用的FBS通常來至牛血清,其中含有大量的牛外泌體。這些外泌體含牛的相關(guān)蛋白質(zhì)或miRNA等分子,當(dāng)你想要研究相關(guān)細(xì)胞自身分泌外泌體時(shí),牛血清中的外泌體可能會(huì)造成嚴(yán)重的背景問題,從而影響或干擾結(jié)果的判斷。

SBI無外泌體血清|SBI*|無外泌體血清說明書
胎牛血清(FBS)已在真核細(xì)胞培養(yǎng)中使用了幾十年了。然而,很少有人關(guān)注FBS的RNA對培養(yǎng)的細(xì)胞會(huì)產(chǎn)生什么樣的生物學(xué)效應(yīng)。來自哈佛醫(yī)學(xué)院的研究人員用RNA測序,證明了FBS含有蛋白質(zhì)編碼和調(diào)控的多種RNA,包括mRNA、miRNA、rRNA和snoRNA等。它們中的大多數(shù)(>70%)仍然存在于細(xì)胞外囊泡(EV)和細(xì)胞間通訊研究中常使用的長時(shí)間超速離心得到的無囊泡FBS(vesicle-depleted FBS, vdFBS)中。FBS相關(guān)的RNA會(huì)在分離細(xì)胞外膜泡RNA(exRNA)時(shí)一同被分離出來,這會(huì)對下游RNA分析造成干擾。許多進(jìn)化上保守的FBS源的RNA種類會(huì)被錯(cuò)誤地認(rèn)為是人或小鼠細(xì)胞的轉(zhuǎn)錄本。值得注意的是,在FBS中含量豐富的一些miRNAs,如miR-122、miR-451A和miR-1246,先前已被報(bào)道為在培養(yǎng)細(xì)胞來源的細(xì)胞外膜泡中富含的miRNAs,這可能是胎牛血清中miRNAs造成的假象。對公開可用的exRNA數(shù)據(jù)庫的分析支持FBS污染的概念。此外,F(xiàn)BS轉(zhuǎn)錄本可被培養(yǎng)的細(xì)胞吸收,并影響高度敏感的基因表達(dá)譜技術(shù)的結(jié)果。因此,實(shí)驗(yàn)設(shè)計(jì)過程中采取減少FBS源RNA干擾的預(yù)防措施是非常有必要的。
