Diluting stock primers

Dilution Calculator by Molarity - Dilute solution to a desired Molarity. This calculator is useful for diluting primers and DNA oligos. This calculator is useful for diluting primers and DNA oligos. Resuspension Calculator: Moles to Molarity - Used to determine how much liquid is needed to resuspend a number of moles to a desired molarity. The first step in this process is to spectrophotometrically analyze the primer to determine its absorbance at 260 nm (known as A260). So as not to waste the precious primer, the researcher diluted it 1:100 in 1X TE buffer to achieve a final volume of 1 mL (10 µL primer solution and 990 µL of 1X TE—this is a dilution factor of 100).

Primers: The sequence and concentration of the primers, as well as amplicon 52043). RNA stocks and dilutions should be made in DEPC- template dilution. 1 Feb 2010 Avoid repeated freezing and thawing by preparing aliquots of working stock solution (typically at 10 μM concentration) adequate for  SAMPLE CALCULATION for DILUTION OF LIQUID PRIMER DNA. Suppose a For PCR, you need two primers, so make concentrated master stocks for both. The most common concentration for a working primer solution is 10 μM. To make a 10 μM working primer solution, follow these steps: Add 10 μL of primer stock solution to an RNase- and DNAse-free tube. Add 90 μL of PCR-grade water. Mix by vortexing. Aliquot and store working primer solutions at -20 o C. Avoid excessive freeze-thawing of working primers. Primers are often shipped and received in a lyophilized state. First create a master 100 × stock (for each primer and then dilute it to a 10× working stock. This reduces the number of freeze/thaw cycles that the master primer stock goes through and reduces the chances of contaminating the primary source for the primer.

I have to use 10 pmol primers in my PCR protocol however I couldn't get how to dilute them. The stock concentration is 100 nmol.

Filter using one or more categories  Mix the solution by vortexing to reconstitute the primers. Store primer stocks at - 20oC. 2. Make a working primer solution. You should never use the stock primers  

Add an aliquot of the resuspended oligonucleotide to a final volume of 1,000 µl with water (water = 1,000 µl – volume of oligonucleotide added). Vortex or pipette up and down for 15 seconds. Read the absorbance of this dilution at 260 nm (A260).

To dilute the primer and probe, use the following calculation. C 1V 1=C 2V 2 Where C 1 = Initial Concentration of solution V 1 = Initial Volume of solution C 2 = Final Concentration of solution V 2 = Final Volume of solution Solve for V 1 to calculate the volume of each stock primer needed per reaction. 50 μmols V 1 = 0.9 μmols 50 μl In the same way, I am lowering my vendor stock to a 1:10 stock solution and preparing a 5pmol/ul working solution from that. Because the primer from the vendor is higher in my case, I will have to dilute it down. I guess this is the reasoning behind the 1:10 dilution. Also, you are resuspending your vendor stock in 285 ul water or TE buffer. Note: 2.0 μL of each primer will be added to the reaction of 20 μL total volume. For this reason, primer stocks are 10 times the required concentration to achieve the desired final concentration. 1. Using the 10 μM primer stock, make a dilution of both primer stocks to 0.5, 1, 2, 4, 6 and 8 μM as shown in Table P13-32.

To prepare primer for use: Dilute this stock 1:10, to give a concentration of 10 mM. From this, use 1 ml in a typical PCR reaction. This will give you a final concentration of 10 pmoles in a PCR reaction.

Dilution of Stock Multiplex primers. If you are performing sequencing on the 454 GS FLX or GS Junior. Sequencers, see Advanced Development Protocol 21,  Our general practice is to make a 100 μM stock solution with TE and then dilute to a 10-20 μM working solution using Tris pH 8.3 or filtered ddH2O.
