TAG-72 腫瘤相關(guān)糖蛋白

廣州健侖生物科技有限公司

B72.3抗體可以識別一種名為TAG-72的高分子量糖蛋白，該蛋白主要在腺癌中表達(dá)而間皮瘤是陰性，研究表明在肺腺癌有80%的敏感性和超過90%的特異性。當(dāng)然，在用該抗體研究間皮瘤和腺癌時，注意假陽性反應(yīng)，可與其它抗體結(jié)合使用。

在我們的太陽系中，水可以說是無處不在。不只地球上有水，那些冰質(zhì)彗星和衛(wèi)星上也有水，甚至連水星上永遠(yuǎn)曬不到陽光的陰影盆地中也有水冰的存在。水還存在于來自隕石、月球和火星的礦物樣本之中。尤其是彗星和小行星，由于本身就較為原始，它們?yōu)槲覀兲栂翟缙诘沫h(huán)境提供了天然的“時間膠囊”。
在太陽尚處在幼年時，它被一個原行星盤所包圍，也就是所謂的“太陽星云”(solar nebula)，行星便在其中誕生。但是，科學(xué)家此前一直不太清楚，太陽星云中的冰，到底來源于太陽形成之前的星際分子云，還是在太陽形成的過程中全部被破壞然后又通過化學(xué)反應(yīng)重新形成的。
“為什么這個問題很重要?如果早期太陽系里的水是從星際空間直接繼承過來的原始物質(zhì)，那么類似的水冰，以及它們所包含的前生命有機物質(zhì)，就很有可能大量存在于大多數(shù)甚至全部正在形成的恒星周圍的原行星盤中。”美國卡內(nèi)基學(xué)院參與了這項研究的科內(nèi)爾·亞歷山大(Conel Alexander)解釋說，“然而，如果早期太陽系里的水主要來自于太陽誕生時發(fā)生的化學(xué)反應(yīng)，那么在不同的正在行成的行星系統(tǒng)中，水的含量就可能千差萬別，這顯然會對太陽系外其他地方涌現(xiàn)出生命的可能性產(chǎn)生影響。”

Water can be ubiquitous in our solar system. Not only is there water on Earth, there are also water on ice-bound comets and salites, and there is ice in the shaded basins that never reach the sunshine on Mercury. Water is also present in mineral samples from meteorites, the moon and Mars. In particular, comets and asteroids, by their very nature, provide natural "time capsules" for the early environment of our solar system.
When the sun is still in its infancy, it is surrounded by a primitive planet plate, the so-called solar nebula, in which planets are born. However, scientists have been less clear about whether the ice in the solar nebula, in the end, originated from the interslar cloud of clouds before the sun was formed or compley destroyed by the sun's formation and then re-formed by chemical reactions.
"Why is this important? If the water in the early solar system was directly derived from interslar space, then similar water ice and the pre-life organic matter they contained were most likely to exist in large quantities even in most All of the protoplanets that are forming around the stars. "Explained Conel Alexander, who participated in the study at the Carnegie Institution of the United States." However, if the water in the early solar system came mainly from the birth of the sun The chemical reactions that take place can have very different levels of water in different planetary systems that are going on and that will obviously have an impact on the likelihood of life in other places outside the solar system.
