产品提供形式：

Liquid or Lyophilized powder

缓冲液：

If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.

储存条件：

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.

保质期：

The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20℃/-80℃. The shelf life of lyophilized form is 12 months at -20℃/-80℃.

货期：

13-23 business days

注意事项：

Repeated freezing and thawing is not recommended. Store working aliquots at 4℃ for up to one week.

功能1：

Chalkophore involved in scavenging, uptake and suppression of toxicity of copper. Each apo-methanobactin (apo-mb) complexes 1 Cu(2+) or Cu(1+) ion to form Cu(1+)-mb (Cu-mb) which is then taken up by the cell. Enhances growth rate in the presence of copper and reduces growth lag upon exposition to elevated levels of copper. Cu-mb contributes to the switchover from soluble methane monooxygenase (sMMO) to the membrane-bound particulate MMO (pMMO) by inducing transcription of pMMO subunit A. It also stimulates the enzymatic activity of pMMO. In the absence of copper, binds other metal ions, like Zn(2+), Ag(1+), Au(3+), Co(2+), Cd(2+), Fe(3+), Hg(2+), Mn(2+), Ni(2+), Pb(2+) or U(6+), but not Ba(2+), Ca(2+), La(2+), Mg(2+) or Sr(2+). Uptake is an active process, which may involve TonB-dependent transporters, and as such does not involve porins. Cu-Mb can be taken up by other methanotrophic bacteria but not by E.coli. Has Cu-dependent superoxide dismutase-like activity. Shows reductant-dependent oxidase and hydrogen peroxide reductase activities. Reduces copper-levels in liver in a rat model of Wilson disease.
