分子别名（Synonym）:AAA,ABETA,ABPP,AD1,APPI,CTFgamma,CVAP,PN-II,PN2

种属（Species）：Human

表达系统（Expressed Host）：E. coli

产品状态（Buffer）：Lyophilized from sterile 50mM Tris, 500mM NaCl, pH 7.5

分子量（Molecule Mass）：The recombinant human Beta-APP40/GST chimera consists of 278 amino acids and has a calculated molecular mass of 31.8 kDa. It migrates as an approximately 33 kDa band in SDS-PAGE under reducing conditions.

内毒素（Endotoxin）：＜1.0 EU per μg by the LAL method.

生物活性(Activity)：Measured by its ability to bind biotinylated recombinant human AGER (Cat:H2853-CCH) in a functional ELISA.

表达区间（Protein Construction）：A DNA sequence encoding the amino acids (Asp 672-Val 711) of human Amyloid beta A4 protein (APP770) (P05067-1), corresponding to the Beta-amyloid protein 40, was fused with the N-terminal polyhistidine-tagged GST tag at the N-terminus.

存储条件（Storage）： For long term storage, the product should be stored at lyophilized state at -20℃ or lower.Please avoid repeated freeze-thaw cycles. No activity loss is observed after storage at:4-8℃ for 12 months in lyophilized state;-70℃ for 3 months under sterile conditions after reconstitution.

运输条件： In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
