表達區(qū)間及表達系統(tǒng)(Source)
Human ITGA4&ITGB7 Heterodimer Protein, His Tag&Tag Free (IT7-H52W4) is expressed from human 293 cells (HEK293). It contains AA Tyr 34 - Thr 977 (ITGA4) & Glu 20 - His 723 (ITGB7) (Accession # P13612-1 (ITGA4) & P26010-1 (ITGB7)).
Predicted N-terminus: Tyr 34 (ITGA4) & Glu 20 (ITGB7)
蛋白結(jié)構(gòu)(Molecular Characterization)
Human ITGA4&ITGB7 Heterodimer Protein, His Tag&Tag Free, produced by co-expression of ITGA4 and ITGB7, has a calculated MW of 111.4 kDa (ITGA4) & 83.7 kDa (ITGB7). The protein migrates as 55 kDa, 80 kDa, 100-120 kDa and 130-150 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under non-reducing (NR) condition (SDS-PAGE) due to glycosylation.
內(nèi)毒素(Endotoxin)
Less than 1.0 EU per μg by the LAL method.
純度(Purity)
>90% as determined by SDS-PAGE.
制劑(Formulation)
Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 150 mM NaCl, pH7.5 with trehalose as protectant.

背景(Background)
整合素α4β7是一種整合素家族粘附受體,與α4β1(VLA4)和E-鈣粘蛋白受體αEβ7共享亞基。整合素α4β7,對歸巢腸粘膜至關(guān)重要,在Peyer斑塊或腸系膜淋巴結(jié)的T細胞活化過程中被誘導。它的表達需要來自局部樹突和基質(zhì)細胞的信號,包括分泌的視黃酸。HIV-1包膜蛋白gp120與整合素α4β7的活性形式結(jié)合,這可以解釋也可以不解釋HIV-1病毒在腸道相關(guān)淋巴組織(GALT)中的濃度。整合素α4β7也可能參與急性腸移植物抗宿主?。?/span>GVHD)中的淋巴細胞運輸。
