Cardiac Hypertrophy and Fibrosis Induction

Check if the same lab product or an alternative is used in the 5 most similar protocols
Adult mice >20.0 g were infused with AngII/PE to induce cardiac hypertrophy and fibrosis. Mice were anesthetized with 1–2% isoflurane and mini-osmotic pumps (Alzet, 2001, 2002, or 2004) were implanted subcutaneously. A combination of 1.5 μg/g/day angiotensin II (Calbiochem, 05-23-0101) and 50 μg/g/day phenylephrine hydrochloride (Sigma, P6126) or saline, was infused for 7, 14, or 28 days.

Purified CD4 T cells were stimulated with 10μg/ml plate bound anti-CD3ε (clone 145-2C11) and 2μg/ml soluble anti-CD28 (37.51) in RPMI 1640 as before in flat bottom 96 well plates. For Th1 polarisation, cells were also treated with 15ng/ml recombinant mouse IL-12 and 5μg/ml anti-IL-4 (11B11), or for Th2 polarisation, 30ng/ml recombinant mouse IL-4 and 5μg/ml anti-IFNγ (XMG1.2). Phenylephrine hydrochloride (Sigma) was used at 10μM and added during both anti-CD3 dependent activation (4 days) and also during rest in 10U/ml recombinant human IL-2 (2 days). All antibodies were from Biolegend and were low endotoxin / azide free, and recombinant cytokines were from Peprotech.

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.
