PLGA scaffold problem

... inside the scaffold. I will investigate in vitro and in vivo effect of this compound. Because it is water solule I could not use salt (particle) leaching method for the production of pores inside the scaffold. I do not have any computarized system so it should be manuel. As additional note this ...

Re: inactive enzyme after purification with Ni-TED

... resins and metalloproteins. First, the background buffer is typically phosphate which can form soluble and insoluble complexes with metals, leaching them off the protein in the process. Second, imidazole can also complex metal ions. You use high(er) concentrations of imidazole to compete ...

What part of a dead tree doesn't biodegrade

... then convert the carbon to new forms (granted, some of it will become gaseous). Ultimately, much of this carbon finds its way into the soil (acid leaching takes it beyond the a-horizon). Also, much of the carbon is drained off into streams and rivers, and ultimately is deposited in alluvials, ...
