Summer Internship Bench Research Training

The interns will observe and practice the following techniques prior to the actual start of their original research projects.

Laboratory safety:

• Explain the dress code that needs to be observed (lab coats, closed shoes, etc.), designated workareas, and the basic safety procedures to be followed.

Pipetting:

• Explain the different types of pipettes (transfer pipette, micropipette, pipettor), when theyshould be used and how they should be operated.

• Exercise - Pipette 3 volumes (1000µL, 100µL and 10µL) x 15 repeats

Microscopy:

• Explain the various types of microscopes, the function of different components as well as theproper operating and cleaning procedures (Tutorial)

General handling of a semen sample:

• Explain and demonstrate the basics to be performed when a semen sample was received:Incubation, Recording of information, Liquifaction, transfer, volume, pH, Viscosity, Color

Microbeads:

• Explain the loading of a microcell, setting up of the microscope (x20 phase contrast), countingtechnique and calculations

• Exercise – Count 2 concentrations x 3 each

Sperm count and Concentration:

• Explain the loading of a microcell, setting up of the microscope (x20 phase contrast), countingtechnique and calculations

• Exercise – Analyse 10 x samples

Vitality

• Explain the principles of employing a dye exclusion staining technique for viabilitymeasurement, preparing the sample, making of the smear, coverslip slide, and evaluating thesample

• Exercise – Prepare and score x 5 slides

Morphology:

• Explain the principles of morphology, the preparation, staining and evaluating of slides

• Demonstrate – Slide preparation, staining, scoring

• Exercise – Only identified students will receive further training
