Four-phase Streaking method

Researcher: Leng Yi-Yan, Chang Chun-chieh, Lee Ming-Jhen
Place: Fu Jen University Food Science Department
Date: August 31th, 2015

Purpose

Plate streaking is an important and essential technique in molecular biology. Streaking allows the selection of a single colony from an original mixture of colonies. It also allows for the selection of one single colony from an original plate to be grown up as many colonies on a new plate.

Material

E.coli(DH5α)
Solid medium(LB agar)
Inoculating loop
Alcohol Burner

Procedure

Step1: Sterilize the inoculating loop on an alcohol burner flame and allow it to cool for a few seconds.

Step2: Using the loop, streak the first section of the plate using tight sweeping lines that stay within that section.

Step3: Sterilize the loop and allow it to cool in the air for 15 seconds. Touch the loop to an unused edge of the agar surface to cool it completely before continuing.

Step4: Pull the loop through the previous streak one or two times to re-inoculate the loop with cells.

Step5: Streak section 2 of the plate, avoiding section 1 after the first 1-2 streaks and trying not to overlap the streaks.

Step6: Repeat Step3,4,5 for two more times.

Preparing Samples

Homogenizing samples

Determine your sample type, and perform homogenization at room temperature according to the table below. The sample volume should not exceed 10% of the volume of TRIzol Reagent used for homogenization. Be sure to use the indicated amount of TRIzol Reagent, because an insufficient volume can result in DNA contamination of isolated RNA.

Sample Type

Action

Tissues

Add 1mL TRIzol Reagent per 50-100 mg of tissue sample.
Homogenize sample using a glass-Teflon or power homogenizer.

Note: Process or freeze tissue samples immediately upon collection.

RNA Isolation Procedurec

Always use the appropriate precautions to avoid RNase contamination when preparing and handling RNA.

RNA precipitation

(Optional) When precipitating RNA from small sample quantities (<10⁶ cells or < 10 mg tissue), add 5-10μg of RNase-free glycogen as a carrier to the aqueous phase.
- Note: Glycogen is co-precipitated with the RNA,but does not inhibit first-strand synthesis at concentrations ≤4mg/mL,and does not inhibit PCR.
Add 0.5mL of 100% isopropanol to the aqueous phase, per 1mL of TRIzol Reagent used for homogenization.
Incubate at room temperature for 10 minutes.
Centrifuge at 12,000 × g for 10 minutes at 4℃.
- Note: The RNA is often invisible prior to centrifugation, and forms a gel-like pellet on the side and bottom of the tube.
Proceed to RNA wash.

Proceed to RNA wash.

Remove the supernatant from the tube,leaving only the RNA pellet.
Wash the pellet,with 1mL of 75% ethanol per 1mL of TRIzol Reagent used in the initial homogenization.
- Note: The RNA can be stored in 75% ethanol at least 1 year at-20℃, or at least 1 week at 4℃.
Vortex the sample briefly,then centrifuge the tube at 7500 × g for 5 minutes at 4℃.Discard the wash.
Vacuum or air dry the RNA pellet for 5-10 minutes. Do not dry the pellet by vacuum centrifuge. <ul class="note-unordered-list"
Note: Do not allow the RNA to dry completely,because the pellet can lose solubility.Partially dissolved RNA samples have an A_260/280 ratio<1.6.

</ul>

Proceed to RNA resuspension.

</ol>

RNA resuspension

Resuspend the RNA pellet in RNase-free water or 0.5% SDS solution(20-50㎕) by passing the solution up and down several times through a pipette tip.
- Note: Do not dissolve the RNA in 0.5% SDS if it is to be used in subsequent enzymatic reactions.
Incubate in a water bath or heat block set at 55-60℃ for 10-15 minutes.
Proceed to downstream application, or store at -70℃.

Date: April 2nd, 2015

Procedure

Harvesting

Transfer 1.5ml of cultured bacterial cells to a 1.5ml microcentrifuge tube. Centrifuge at 13000 x g for 1 minute at room temperature.

Resuspension

Add 200μl of PD1 Buffer to a new 1.5ml microcentrifuge tube. Add 2μl of TrueBlue Lysis Buffer to the same 1.5ml microcentrifuge tube then mix by shaking gently.

Cell Lysis

Add 200μl of PD2 to the resuspended sample then mix genlly by inverting the tube 10 times. Let stand at room temperature for at least 2 minutes to ensure the lysate is homogeneous. Do not exceed 5 minutes.

Neutralization

Add 300 μl of PD3 Buffer then mix immediately by inverting the tube 10 times. Centrifuge at 13000 x g for 3 minutes at room temperature.

DNA Binding

Transfer all of the supernatant to thePDH Columg. Centrifuge at 13000 x g for 30 seconds at room temperature then discard th flow-through. Place the PDH Column back in the 2 ml Collection Tube.

Wash

For Improved Downstream Sequencing Reactions

Add 400 μl of W1 Buffer into the PDH Column. Centrifuge at 13000 x g for 30 seconds. Discard the flow-through then place the PDH Column back in the 2 ml Collection Tube. Proceed with Wash Buffer addition.

For Standard Plasmid DNA Purification

Add 600 μl of Wash Buffer into the PDH column. Centrifuge at 13000 x g for 30 seconds at room temperature. Discard the flow through then place the PDH Column back in the 2 ml Collection Tube. Centrifuge at 13000 x g for 3 minutes at room temperature to dry the column matrix.
