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 recombinant rat FCGR2B comprises 192 amino acids and predicts a molecular mass of 21.9 kDa. The apparent molecular mass of the rat FCGR2B is approximately 35-40 kDa in SDS-PAGE under reducing conditions due to glycosylation.
内毒素（Endotoxin）：＜1.0 EU per μg by the LAL method.
生物活性(Activity)：Measured by its binding ability in a functional ELISA.
表达区间（Protein Construction）：A DNA sequence encoding the rat FCGR2B (Q63203-1) extracellular domain (Ser 2-Pro 212) 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
