The wood chips were milled and sieved to yield a suitable substrate for the acid hydrolysis (chips of 2.2 to 10 mm in size).
It could have citric acid, oak chips, concentrated grape juice and chemical preservatives above and beyond sulfur.
After adding sinapinic acid, the chip-bound proteins were profiled using a PCS4000 mass spectrometer (Ciphergen).
Micromachining technology was used to fabricate the anodic molds of integrated nucleic acid extraction microfluidic chip.
Since the pitch of AAM is proportional to the applied anodization potential, high anodization voltage need to be applied to get large-pitch AAM; as a result, the anodization electrolyte should be weak acid to avoid chip burning from occurring.
The metal chips are funneled into a vat of nitric acid where the chips are dissolved into a lethal broth containing about 96percentt uranium and one percent plutonium, plus dozens of other highly radioactive elements.
Prior to pretreatment, that is dilute acid hydrolysis, the chips were impregnated with 3% SO2 (w/w based on the water content of the wood chips).
The cells were immobilized on a dithiodibutyric acid-coated sensor chip, after activation with carbodiimide (16 mM) and N-hydroxysuccinimide (13 mM).
Histone samples, from both ChIP input and ChIP elutions, were prepared as described previously [ 27], with the exception that the acid extraction step was simply replaced by a boiling step for the ChIP elutions.
Additionally, the final detection was performed using a nucleic acid paper-based detection chip, and the results were automatically analyzed by software.
