Human Beta-amyloid 38 / Beta-APP38 Protein (aa 672-709, His & GST Tag)

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制剂（Buffer）：Lyophilized from sterile 50 mM Tris, 100 mM NaCl, 20% glycerol, 0.05% Tween 20, pH 9.5.分子量（Molecule Mass）：The recombinant human Beta-APP38/GST chimera consists of 277 amino acids and has a calculated molecular mass of 32.1 KDa. It migrates as an approximately 34 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)：表达区间（Protein Construction）：A DNA sequence encoding the amino acids (Asp672-Gly709) of human Amyloid beta A4 protein (APP770) (P05067-1), corresponding to the Beta-amyloid protein 38, 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.
