Real time pcr primers

Manufactured by Integrated DNA Technologies
Sourced in United States

Real-time PCR primers are short, synthetic DNA sequences designed for use in real-time polymerase chain reaction (PCR) experiments. These primers are used to amplify and detect specific DNA or RNA targets in a sample, allowing for quantitative analysis of gene expression or the presence of specific genetic sequences.

Total RNA was isolated from approximately 10 million LCLs (both LCL#1 and LCL#89) either left untreated (DMSO control) or treated with 1 μM MG132 for 12 h using TRIzol reagent according to the manufacturer’s instructions (Invitrogen, Thermo Fisher Scientific Inc., Waltham, MA, USA), followed by cDNA preparation using iScript cDNA synthesis kit (BIO-RAD, Hercules, CA, USA) as per manufacturer’s protocol. RNA and cDNA quality and quantity were checked using Synergy H1 Multimode Microplate Reader (BioTek Instruments, Inc., VT, USA). qPCR analysis was performed using iTaq Universal SYBR Green Supermix (BIO-RAD, Hercules, CA, USA) in CFX Connect Real-Time PCR detection System (BIO-RAD, Hercules, CA, USA) with the following thermal profile– 1 cycle: 95°C for 10 min; 40 cycles: 95°C for 15 sec followed by 60°C for 1 min; and finally the dissociation curve at– 95°C for 1 min, 55°C 30 min, and 95°C for 30 sec. Unless and otherwise stated, each sample was performed in duplicate and calculation was made using a 2−ΔΔCT method to quantify relative expression compared with housekeeping gene controls–B2M, GAPDH and RPLPO. The real time PCR primers used in this study were designed from Primer-BLAST (https://www.ncbi.nlm.nih.gov/tools/primer-blast/) and listed in S2 Table. Real-time PCR primers were obtained from Integrated DNA Technologies, Inc. (Coralville, IA, USA).

Total RNA was isolated from approximately 10 million cells using TRIzol reagent according to the manufacturer’s instructions (Invitrogen Inc., CA), followed by cDNA preparation using iScript cDNA synthesis kit (BIO-RAD, Hercules, CA) as per manufacturer’s protocol. RNA and cDNA quality and quantity was measured using Synergy™ H1 Multimode Microplate Reader (BioTek Instruments, Inc., VT, USA). qPCR analysis was performed using SsoFast EvaGreen Supermix (BIO-RAD, Hercules, CA) in CFX Connect™ real-time PCR detection system (BIO-RAD, Hercules, CA) with the following thermal profile—1 cycle: 95 °C for 10 min; 40 cycles: 95 °C for 15 s followed by 60 °C for 1 min; and finally the dissociation curve at – 95 °C for 1 min, 55 °C 30 min, and 95 °C for 30 s. Unless and otherwise stated, each sample was performed in duplicate and calculation was made using a 2−ΔΔCT method to quantify relative expression compared with housekeeping gene control. The relative change in the gene expression levels compared to control sample (untreated) was represented as heat map diagram. The primers used in this study were designed from qPrimerDepot (https://primerdepot.nci.nih.gov/) and listed in Tables S1 and S2. Real-time PCR primers were obtained from Integrated DNA Technologies, Inc. (Coralville, IA, USA).

Total RNA was extracted using Direct-zol RNA Miniprep Plus Kit according to manufacturer’s protocol. Total 1 μg/sample RNA was subjected to cDNA synthesis using the iScript™ cDNA Synthesis Kit (Biorad). The primers used were designed using primer 3 online tools (http://bioinfo.ut.ee/primer3-0.4.0/primer3/) and were obtained from Integrated DNA Technologies (Coralville, Iowa). Quantitative real-time polymerase chain reaction (qRT-PCR) was carried out using an iCycler (Biorad laboratories). All reactions were performed in triplicates. The fold expression was calculated and normalized to the average CT value of HPRT housekeeping gene. The real-time PCR primers were purchased from Integrated DNA Technologies (IDT, Coralville, IA). Primer sequences were as follows: APE1 (Forward: GCTTCGAGCCTGGATTAAGA; Reverse: TTGGTCTCTTGAAGGCACAGT), YAP1 (Forward: GATGAACTCGGCTTCAGGTC; Reverse: TTGGGTCTAGCCAAGAGGTG), CTGF (Forward: TGGAGATTTTGGGAGTACGG; Reverse: CAGGCTAGAGAAGCAGAGCC), CYR61 (Forward: CCCGTTTTGGTAGATTCTGG; Reverse: GCTGGAATGCAACTTCGG), ANKRD1 (Forward: AGCCCTCATGCTTGCTGTAT; Reverse: TTTGTTCATGAATGTGATGAAATC), HPRT (Forward: ACCCTTTCCAAATCCTCAGC; Reverse: GTTATGGCGACCCGCAG).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
