>95% by SDS-PAGE.
Biological Activity
Fully biologically active when compared to standard. One unit of enzyme activity is defined as the amount of enzyme which will hydrolyze 1.0μmol of benzyl penicillin in presence of EDTA at pH 7.0 and at 25℃.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation
Lyophilized from a 0.2μm filtered concentrated solution in 100mM Tris, pH7.0.
Endotoxin
N/A
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
Beta-lactamases are enzymes produced by some bacteria and are responsible for their resistance to beta-lactam antibiotics like penicillins, cephamycins, and carbapenems. The lactamase enzyme breaks the β-lactam ring open and deactivates the molecule's antibacterial properties because of a common element in these antibiotics molecular structure: a four-atom ring known as a betalactam. TEM-1 is the most commonly-encountered beta-lactamase in gram-negative bacteria. Up to 90% of ampicillin resistance in E. coli is due to the production of TEM-1. Also responsible for the ampicillin and penicillin resistance that is seen in H.influenzae and N.gonorrhoeae in increasing numbers. Based upon different combinations of changes, currently 140 TEM-type enzymes have been described. Recombinant beta-lactamase TEM-1 contains 264 amino acids residues.

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引起部分失活，所以**配制成相應(yīng)濃度的儲存液后(請根據(jù)產(chǎn)品簡介中Reconstitution一欄的信息配制儲存液)，須分裝后-20℃或更低溫度凍存，以避免反復(fù)凍融。 注意事項: 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，使細(xì)胞因子或重組蛋白不會粘附于管壁。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，請穿實驗服并戴一次性手套操作。
