Simply so, how much kanamycin do you put on a LB plate?
LB plates plus antibiotics 2. Kanamycin – add 1 ml kanamycin stock (50mg/ml) per liter of agar so the final concentration is 50µg/ml. Mark the plate with “K” on the side.
How long do kanamycin plates last?
Our experience in effectiveness of kanamycin plates is: if properly stored plates can be used for 8-10 days, thereafter plates start to loss their function. After inoculation one should not wait for more than 48 h for selection or Kan-R colonies.

Pour a thin layer (5mm) of LB Agar (~10mL) into each plate being careful to not lift the cover off excessively (you should be able to just open up enough to pour).How many Agar are in a pound plate?
Agar plates with LB medium and ampicillin (50 μg/mL) Dissolve 15 g of Bacto agar in 1.0 L of LB medium and sterilize by autoclaving. Cool to 50°C in a temperature-controlled water bath. Add 0.50 mL of 100 mg/mL ampicillin.At what temperature does kanamycin degrade?
Kanamycin sulfate can be added into agar (agar plate), and the plate should be then be sealed to prevent any evaporation of moisture from the agar. The sealed plate can be stored at 2-8 °C for about one month. If the plate is not sealed to prevent evaporation of moisture, the kanamycin can degrade.What is kanamycin target?
Kanamycin is an aminoglycoside antibiotic. Aminoglycosides work by binding to the bacterial 30S ribosomal subunit, causing misreading of t-RNA, leaving the bacterium unable to synthesize proteins vital to its growth.How do you calculate antibiotic concentration?
Make sure units match!- C1V1 = C2V.
- C = concentration; V = volume.
- Example: You have a stock solution of A at 100mg/ml. You want 150 ml at 100ug/ml.
- (100ug/ml)(150ml) = (100000ug/ml)(x)
- 15000 = 100000x.
- x = 0.15ml, or 150ul.
- Remember that you have to convert mg/ml to ug/ml, which you can do by multiplying by 1000.
