表達區(qū)間及表達系統(tǒng)(Source)
Human / Mouse FGF-8b Protein, His Tag (FGB-H52H1) is expressed from human 293 cells (HEK293). It contains AA Gln 23 - Arg 215 (Accession # P55075-3).
Predicted N-terminus: Gln 23
蛋白結構(Molecular Characterization)

This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 24.3 kDa. The protein migrates as 35-45 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
內毒素(Endotoxin)
Less than 0.1 EU per μg by the LAL method.
無菌(Sterility)
Negative
支原體(Mycoplasma)
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)
FGF8被鑒定為一種雄激素誘導的生長因子,由乳腺癌細胞系分泌,在胚胎發(fā)育過程中廣泛表達。它已被證明介導胚胎上皮-間充質轉化,并在原腸胚形成和中腦/后腦、咽、心臟、泌尿生殖和肢體結構的早期組織和分化中起著關鍵作用。在成年期,FGF8的表達受到更多限制,但在激素性癌癥中,它經常被激活。FGF8亞家族,包括FGF8、FGF17和FGF18,不僅在前列腺、乳腺癌癥中檢測到,而且在肝細胞癌(HCC)中也檢測到。FGF8、FGF17和FGF18參與HCC中的自分泌和旁分泌信號傳導,并增強腫瘤細胞在應激條件下的存活率、惡性行為和新生血管生成。脊椎動物FGF8基因通過選擇性剪接產生多種蛋白質亞型。兩種進化上保守的剪接形式FGF8a和FGF8b表現出不同的生物活性,其中FGF8b由于對FGF受體具有更高的親和力而具有更強的誘導活性。
