About this protein
Name
Recombinant HBsAg-preS2 (Recombinant Hepatitis B Surface Antigen preS2; rHBsAg-preS2)；重組乙型肝炎表面抗原preS2
Synonyms
Middle surface antigen; PreS2
Purity
>95% by SDS-PAGE and HPLC analyses.
Biological Activity
N/A
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation
Lyophilized from a 0.2μm filtered concentrated solution in 20mM PB, pH7.4, 50mM NaCl.
Endotoxin
Less than 1EU/μg of rHBsAg-preS2 as determined by LAL method.
Reconstitution
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0mg/ml. Stock solutions should be apportioned into working aliquots and stored at <-20℃. Further dilutions should be made in appropriate buffered solutions.

Background
Hepatitis B virus (HBV) is a human pathogen, causing serious liver disease. The HBV surface protein antigens (HBsAg) are comprised of three carboxyl co terminal HBs proteins termed large (LHBs), middle (MHBs) and small (SHBs, also called major) protein. LHBs and MHBs also share the highly hydrophobic, repetitive, membrane spanning S domain. In addition, MHBs has a 55 amino acid region called preS2.

保存條件: -20℃或更低溫度保存，至少一年有效。由于蛋白的每次凍融均會(huì)引起部分失活，所以**配制成相應(yīng)濃度的儲(chǔ)存液后(請根據(jù)產(chǎn)品簡介中Reconstitution一欄的信息配制儲(chǔ)存液)，須分裝后-20℃或更低溫度凍存，以避免反復(fù)凍融。 注意事項(xiàng): 由于有些塑料管壁對某些蛋白有較強(qiáng)的吸附作用，溶液中的蛋白很容易粘附在管壁上，并且粘附后的蛋白很難與管壁分離。而載體蛋白(Carrier protein，如0.1% BSA等)的主要作用是預(yù)先封閉塑料管壁上的蛋白結(jié)合位點(diǎn)，使細(xì)胞因子或重組蛋白不會(huì)粘附于管壁。所以一定要使用產(chǎn)品簡介中Reconstitution一欄的信息配制儲(chǔ)存液。 本產(chǎn)品**于專業(yè)人員的科學(xué)研究用，不得用于臨床診斷或**，不得用于食品或藥品，不得存放于普通住宅內(nèi)。 為了您的**和健康，請穿實(shí)驗(yàn)服并戴一次性手套操作。
