Quantifying BMP4 Expression in HUVECs and Mouse Tissues

Check if the same lab product or an alternative is used in the 5 most similar protocols
Total RNA from cultured HUVECs or previously homogenized mouse tissues was isolated and purified using the SpeedTools kit (Biotools), or the RNeasy kit (170-8891; iScript cDNA Synthesis kit; BioRad). One μg of total RNA from each sample was retrotranscribed into cDNA with the iScript cDNA Synthesis kit (BioRad) in a final volume of 20 μL, following the manufacturer’s instructions. The resulting cDNA was used as a template for subsequent quantitative real-time PCR. For qRT-PCR assays of human BMP4, specific oligonucleotides labeled with FAM (Hs03676628_s1; TaqMan Gene Expression Assays, Applied Biosystems), and Roche’s FastStart Essential DNA Probes Master Mix containing Taq DNA Polymerase (Life Science). Amplification experiments were performed with the iQ5 thermal cycler (Bio-Rad). The qRT-PCR of murine Bmp4 was carried out using the iQTM SYBR® Green Supermix (170-8880; BioRad), and mouse Bmp4 specific oligonucleotides (Forward, CGTTACCTCAAGGGAGTGGA; Reverse, ATGCTTGGGACTACGTTTGG). DNA amplification was performed with the Roche LightCycler 96 thermal cycler, using human or murine 18S ribosomal RNA as an internal control. Samples were analyzed in triplicate, and each experiment was repeated at least three times. Results were normalized with respect to the expression levels of the 18S ribosomal RNA by the 2−ΔΔCt method.

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.
