分子別名(Synonym)
EGF,URG,HOMG4
表達(dá)區(qū)間及表達(dá)系統(tǒng)(Source)
Human EGF, Mouse IgG2a Fc Tag (EGF-H525b) is expressed from human 293 cells (HEK293). It contains AA Asn 971 - Arg 1023 (Accession # P01133-1).
Predicted N-terminus: Glu
蛋白結(jié)構(gòu)(Molecular Characterization)
This protein carries a mouse IgG2a Fc tag at the N-terminus.
The protein has a calculated MW of 33.1 kDa. The protein migrates as 35 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.
純度(Purity)
>95% as determined by SDS-PAGE.
制劑(Formulation)
Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5 with trehalose as protectant.

背景(Background)
人表皮生長(zhǎng)因子(EGF)也稱(chēng)為HOMG4和URG,是一種通過(guò)與其受體EGFR結(jié)合在調(diào)節(jié)細(xì)胞生長(zhǎng)、增殖和分化中起重要作用的生長(zhǎng)因子。表皮生長(zhǎng)因子存在于人類(lèi)血小板、巨噬細(xì)胞、尿液、唾液、乳汁和血漿中。EGF是EGF蛋白家族的創(chuàng)始成員。這個(gè)蛋白質(zhì)家族的成員具有高度相似的結(jié)構(gòu)和功能特征。所有家族成員都包含一個(gè)或多個(gè)保守氨基酸序列的重復(fù)。唾液EGF的生物學(xué)效應(yīng)包括口腔和胃食管潰瘍的愈合、胃酸分泌的抑制、DNA合成的刺激以及粘膜對(duì)胃酸、膽汁酸、胃蛋白酶和胰蛋白酶等管腔內(nèi)損傷因素以及物理、化學(xué)和細(xì)菌因子的保護(hù)。由于EGF增加了患癌癥的風(fēng)險(xiǎn),抑制它可以降低癌癥的風(fēng)險(xiǎn)。
