Procedure Day II
1.
Collect at least 2 mL of saliva.
2.
Place 1 mL of saliva in a tube labeled “Protein” and add 0.1 mL of 10X sample buffer. 3.
load 20
L of your sample into one of the wells in a protein electrophoresis gel.
4.
Place 1 mL of saliva in another tube labeled “Amylase” and make the following dilutions: 1/10 = 250
L saliva + 2.25 mL TBE buffer, 1/300 = 100
L 1/10 dilution + 2.9 mL TBE buffer 5.
add 900
L of the 1/300 dilution to another tube and mix with 0.1 mL of 10X sample buffer.
6.
load 10
L of your sample into one of the wells in another protein electrophoresis gel.
7.
Both gels will be treated differently for you to be able to answer the follow-up questions. Make sure you understand what each gel treatment involves and why it is done.
1.
Based on the “Protein” gel, how many different proteins can you identify in your saliva sample?
Based on the results from well 6, one protein was identified in the saliva sample
2.
Based on the “Amylase” gel, which band do you think contains the amylase protein?
The white band seen in lane 7, the only band, contains the amylase protein. This is because the total protein gel also contained only one band, indicating the presence of only one protein.

Case Study: Catalase Activity
Catalase

+ O2 (2)
Catalase is an enzyme that converts hydrogen peroxide
(H,O) to oxygen and water. An experiment investigated
the effect of temperature on the rate of the catalase
reaction Small (10 cm) test tubes were used for the
reactions, each containing 0.5 cm of enzyme and
4 cm of hydrogen peroxide. Reaction rates were
assessed at four temperatures (10°C, 20°C, 30'C. and
60 C). For each temperature, there were two reaction
tubes (e.g. tubes 1 and 2 were both kept at 10°C). The
height of oxygen bubbles present after one minute of

reaction was used as a measure of the reaction rate: a

experiment, involving eight tubes, was repeated on two
separate days.

Case Study Four
Case Study Assessing Dose Accuracy and Safety and Label Clarity
The Pharmacy Department of Miracle Hospital has ordered premixed solutions of cyclophosphamide 200 mg per 500 mL of NaCl 0.9%w/v injection from a specialty pharmacy compounding various parenteral products. The commercial 500 mL NS solution PVC bag has an overfill.
The specialty pharmacy prepared the cyclophosphamide admixture by adding 10 mL of a reconstituted solution of 20 mg/mL cyclophosphamide to the 500 mL of NaCl 0.9%w/v PVC bag and labelled the IV admixture as 200 mg of cyclophosphamide per 500 mL.
What is the concentration per millilitre of the cyclophosphamide admixture? (Napra 3.1)
What volume of this admixture would you draw-up in a syringe to deliver a 40 mg dose? (Napra 3.1)
What potential error could result if the premixed cytotoxic admixture is used? (Napra 6.1, 6.2, 9.2)

Procedure:
1.Take a clean sweet potato and peel the skin off.2.Weigh the peeled sweet potato and note the weight.3.The sweet potato is cut into small pieces and transferred into a mortar and pestle.4.The pieces are crushed and then transferred into a blender.5.Add 40 ml of cold 20mM sodium phosphate buffer saline.

Exercise 1: Standard Curve for Protein Measurements:
A standard curve for protein concentration is often created using known concentrations of bovine serum albumin (protein).
This process is called the Bradford Assay; it is a colorimetric assay. A special reagent turns blue when it binds to amino
acids present in protein. The intensity of the color is best measured with a spectrophotometer (a device for comparing two
light radiations, wavelength by wavelength). In the case of the Bradford Assay the greater the absorbance, the higher the
protein concentration.
A series of tests were performed on some samples and
spectrophotometer:
following measurements were obtained using a
