分子别名(Synonym):FLT,FLT-1,VEGFR-1,VEGFR1
种属(Species):Human
表达系统(Expressed Host):HEK293 Cells
产品状态(Buffer):Lyophilized from sterile PBS, pH 7.4
分子量(Molecule Mass):The secreted recombinant human VEGFR1 consists of 741 amino acids with the predicted molecular mass of 83.7 kDa. As a result of glycosylation, rhVEGFR1 migrates as an approximately 110-120 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 inhibit the VEGF-dependent proliferation of human umbilical vein endothelial cells (HUVEC) (Conn, G. et al.,1990 , Proc. Natl. Acad. Sci. USA 87:1323.). The ED50 for this effect is typically 10-40 ng/mL in the presence of 10 ng/mL human VEGF165.
表达区间(Protein Construction):A DNA sequence encoding the human VEGFR1 (P17948-1) extracellular domain (Ser 2-Asn 756) was expressed, fused with a polyhistidine tag at the C-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.
Store it under sterile conditions at -20℃ to -80℃ upon receiving. Recommend to aliquot the protein into smaller quanti ϻ ϻ ϻ ϻ ϼ ϼ ↓_xFFFF_ Ɛ Ā䀀܀Microsoft New Tai Lue 耈ᨘ↓_xFFFF_ Ɛ 蘀䀀✀宋体 ⨠ቻ↓_xFFFF_ Ɛ 脀䀀܀Malgun Gothic 樀᧤↓_xFFFF_ Ɛ 蘀䀀܀Ebrima ᨓ 쭹싘헨̧
