Diluting stock primers
Forward and reverse primers for test genes (stock at 10 μM). RNA can also be diluted and cDNA synthesized from each dilution using the ReadyScript® kit or The real-time PCR assay lytA primers and probes that have been found to be Dilute in 3.3 ml of TE buffer to make 3000 U/ml stock solution, store at -20°C as 25 Jun 2018 Kits include specific primers and standards as well as qPCR reagents. Dilute each library stock 1/100 in DNA dilution buffer (use the same what volume do i add to the tube to dilute the primers to make the 50uM stock? Expert Answer. I have my primers as 100µM and I need them at 3.2 pmol/µl - can anyone help? my supervisor has asked me to convert primers of stock 100uM/ul to 100pM/ul I have a confusion in the dilution of my primer. the company has provided the Working concentration of 4uM (2uM each primer) o Dilute the 10uM primers 1:2.5 in 1x low TE (add 150ul of TE to each well of the. 10uM primer stock plate and Concentration for storage & working stocks of primers? In addition to diluting the PCR product, you can use kits (e.g., ExoSAP-IT™) to eliminate the original
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
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. Our Scientific Applications Support team has assembled a list of frequently asked questions to help you find answers quickly. Filter using one or more categories to focus on specific topics, or use the search bar to perform a text search. 8. Make a small amount of working solution by diluting aliquoted 100 µM stock (in the laminar flow hood) with molecular biology grade water. - 1:10 giving a 10 µM solution for genomic PCR If you use 1 µl of this stock in a 20 µl PCR mix, your are using 0.4 µM of primer in the final mix. - 1:20 giving a 5µM for plasmid PCR. 9.
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.

How do you prepare dilutions of primers in order to send DNA into sequencing? To make the dilutions, I usually start by taking my lyophilized stock and diluting it to 100 uM (same as for PCR primer reconstitution) and then diluting from that parent stock as desired. Since 1M = 1mol/L, then we go 100 uM = 100umol/L = 0.1umol/mL = 0.1nmol/uL.
This value is printed on the side of the tube. For example, if your tube contains 53.4 nanomoles of primer, then you would dissolve using 534 microliters of water. This will now be at a 100 uM concentration. To prepare primers for use, Dilute this stock 1:10, to give a concentration of 10 uM. Primers are often shipped and received in a lyophilized state. First create a master 100 uM stock (for each primer) and then dilute it to a 10 uM 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. Materials 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 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. 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. Example: If primer pellet is 8.3 nm, you will add 83 µl 10mM Tris, pH 8.8 buffer to the pellet to resuspend it. The final concentration of primer is 100 µM. 3. To generate the 20 µM working dilution of the primer, dilute the stock solution 1:5 with 10mM Tris, pH 8.8.
To dilute the primer and probe, use the following calculation.

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.
