分子別名(Synonym)
GM-CSF,CSF2,MGC131935
表達(dá)區(qū)間及表達(dá)系統(tǒng)(Source)
Mouse GM-CSF Protein, Tag Free (GMF-M5211) is expressed from human 293 cells (HEK293). It contains AA Ala 18 - Lys 141 (Accession # P01587).
Predicted N-terminus: Ala 18
蛋白結(jié)構(gòu)(Molecular Characterization)
This protein carries no "tag".
The protein has a calculated MW of 14.1 kDa. The protein migrates as 17-23 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
內(nèi)毒素(Endotoxin)
Less than 0.1 EU per μg by the LAL method.
無(wú)菌(Sterility)
Negative
純度(Purity)
>90% as determined by SDS-PAGE.
制劑(Formulation)
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

背景(Background)
粒細(xì)胞巨噬細(xì)胞集落刺激因子(GM-CSF)也稱(chēng)為集落刺激因素2(粒細(xì)胞-巨噬細(xì)胞),是一種細(xì)胞因子,最初的特征是能夠誘導(dǎo)粒細(xì)胞和巨噬細(xì)胞從髓系祖細(xì)胞集落,由巨噬細(xì)胞、T細(xì)胞、肥大細(xì)胞、內(nèi)皮細(xì)胞和成纖維細(xì)胞分泌。GM-CSF是一種細(xì)胞因子,具有白細(xì)胞生長(zhǎng)因子的功能。GM-CSF刺激干細(xì)胞產(chǎn)生粒細(xì)胞(中性粒細(xì)胞、嗜酸性粒細(xì)胞和嗜堿性粒細(xì)胞)和單核細(xì)胞。單核細(xì)胞退出循環(huán)并遷移到組織中,然后成熟為巨噬細(xì)胞和樹(shù)突狀細(xì)胞。因此,它是免疫/炎癥級(jí)聯(lián)反應(yīng)的一部分,通過(guò)該級(jí)聯(lián)反應(yīng),少量巨噬細(xì)胞的激活可以迅速導(dǎo)致其數(shù)量的增加,這是對(duì)抗感染的關(guān)鍵過(guò)程。該蛋白質(zhì)的活性形式在細(xì)胞外以同二聚體的形式存在。成熟形式的人GM-CSF糖基化。作為免疫/炎癥級(jí)聯(lián)反應(yīng)的一部分,GM-CSF促進(jìn)Th1偏向的免疫反應(yīng)、血管生成、過(guò)敏性炎癥和自身免疫的發(fā)展,因此值得考慮作為治療靶點(diǎn)。GM-CSF最近也在臨床試驗(yàn)中被評(píng)估為HIV感染患者的疫苗佐劑。初步結(jié)果很有希望。GM-CSF也被用作化療后刺激白細(xì)胞生成的藥物。
