Question

sketch out how you will do the glucose oxidase test. how many vials, kind of samples and how much what goes in each tube.

Answer #1

glucose is first oxidized, catalyzed by glucose oxidase, to produce
gluconate and hydrogen peroxide. The hydrogen peroxide is then
oxidatively coupled with a chromogen to produce a colored compound
which may be measured spectroscopically.

Glucose oxidase catalyse the oxidation of Beta D-glucose present in
the plasma to D glucono -1 ,5 - lactone with the formation of
hydrogen peroxide; the lactone is then slowly hydrolysed to
D-gluconic acid. The hydrogen peroxide produced is then broken down
to oxygen and water .The acidification of blood samples using a
combination of citrate buffer, NaF, and EDTA was more
effective.

How many groups are you allowed to have in an independent
samples t-test? How many groups are you allowed to have in an
one-way ANOVA?

please show me how to do this problem, and write out each step
clearly and neatly. Thank you for your help! much appreciated.
A typical laboratory centrifuge rotates at 4200 rpm. Test tubes
have to be placed into a centrifuge very carefully because of the
very large accelerations.
i) What is the acceleration at the end of a test tube that is 10
cm from the axis of rotation?
ii) For comparison, what is the magnitude of the acceleration a...

You do a survey of business students and liberal arts school
students to find out how many times a week they read a daily
newspaper. In each group, you interview 100 students. You find the
following: Xb = 4.5 times per week Sb = 1.5 Xia = 5.6 times per
week Sia = 2.0 Test the hypothesis that there is no significant
difference between these two samples.

How do you figure out assumptions for a two-tailed z test?

Given 200ul of a 0.5mg/ml stock solution of BSA, how much do you
pipet into a test tube so that you are adding 10ug of BSA to the
test tube? 4ug?

A laboratory is interested in how many times they can use a
specific brand of test tube on a Bunsen burner before it cracks.
Assume that the population is normally distributed. They test 20
test tubes and finding it took reheating them 1111 times until they
cracked, with a standard deviation of 234. Compute the 98%
confidence interval to estimate the average number of times they
can use the tube. You DO need to check CLT here

4. You have been given 2 compounds, [Co(NH3)5(SO4)]Be and
[Co(NH3)5Br]SO4, in separate vials. However you do not know which
compound is in each vial. How would you determine qualitatively
which compounds are in each vial by using instrumental and chemical
techniques. (10)

1. You are presented with three vials each contains a white
fluffy powder. You label the vials A, B, and C, then measure the
melting point of each. The following is the data you collect for
your observations: A: 80-82°C B: 113-114°C C: 80-82°C a) Is it safe
to say A = C? What simple test can verify or refute this statement?
(The correct answer must include how you would interpret the
observations to conclude both the A = C...

Suppose that you carry out a urine culture for each of the
given samples. Calculate the CFU for each of the samples. If a CFU
can not be determined explain why this can not be determined. List
an additional test or media that can be used to further identify
the possible pathogenic organism. NOTE 56 µl was used for each
sample
You obtain a sample from a patient, the estimated concentration
of the bacteria is 108, after 24 hours the...

e. How many grams of HEPES (free acid) would you need to weigh
out to make 1 L of 50 mM HEPES?
f. How many mL of 1 M base (NaOH or KOH) would you need to add
to bring the pH to 7.4?
g. What components (and how much of each) would you add to a
beaker to make 1 L 50 mM HEPES, pH 7.4.
