included with the kit. The replaceable penetration blade allows the user to measure not only the surface, but also the internal pH of the meat. Calibration is automatic at 1 or 2 points, selectable between 2 memorized buffer sets. Battery life is more than 1500 hours and...
CSGALNACT2 ΔCC at a concentration of 4 mg/mL was injected onto a Superdex 200 Increase 10/300 column (Cytiva) connected to an Agilent 1260 Infinity system. The running buffer was 25 mM Na-HEPES pH 7.5, 150 mM NaCl and the flow rate was 0.5 mL/min. Light scattering and ...
[76]. The catholyte was a 50 mM phosphate buffer. Both the anolyte, after mixing, and the catholyte pH were 6.9. The anolyte feed bottles were constantly flushed with N2gas and the solutions were fed at a 1:1 ratio into the recirculation volume at 0.084 and 1.8 mL/min (fixed resp....
Deconvolution (reversing the inherent image distortion specific to a given microscope or other imaging instrument) is usually done by image-processing software as part of image generation. Schaffer collaterals Axon collaterals derived from CA3 pyramidal cells that project to hippocampal area CA1. Schaffer...
"A Field Effect Transistor as a Solid State Reference Electrode", Anal. Chim. Acta. 101, 247 (1978). They laboriously pasted individual capillary tips over the gate region of CHEMFETs, epoxied them in place and then filled them with a pH buffer solution, entirely by hand, to create a re...
Cells were incubated with the activated mPEG for 60 min at room temperature in isotonic alkaline phosphate buffer (50 mM K2HPO4 and 105 mM NaCl; pH 8.0), then washed twice with 25 mM HEPES/RPMI 1640 containing 0.01% human albumin. Murine splenocytes used for in vivo studies were ...
possible to form highly sharp and bright images without giving defects to an image part by incorporating an ethylene oxide adduct having specific groups into the above liquid and specifying the potassium ion content to the total content of alkaline metal cation and ammonium ions to a specific ...
At that time, a rapid pH change in the indicator solution to the acid range occurs, resulting in a very sharp visual color change in a pH-sensitive dye. In preferred embodiments, the specific reaction pairs are enzyme/substrate pairs, preferably urease/urea and yeast/triacetin. A preferred ...
*100% is the specific activity (units/mg protein) of polymerase purified and assayed using Tween 20 and NP-40 EXAMPLE 2 Enzyme Activity Assays DNA polymerase activity was measured by running reactions of 50 μL containing 25 mM TAPS (tris-hydroxymethyl-methylaminopropane sulfonic acid) buffer, ...
In still a further embodiment, the solvent is a buffer. In still a further embodiment, the solvent is a potassium phosphate buffer having a pH of about 7. In one aspect, the invention provides a process for the preparation of Compound 28 comprising reacting Compound 34 with a biological ...
