General description

The Rac1/Cdc42 Activation Assay (Cat. No. 17-441) provides an effective method for detecting Rac and Cdc42 activity in cell lysates. This assay uses the downstream effector of Rac/Cdc42, p21-activated protein kinase (PAK1), to isolated the active GTP-bound form of Rac/Cdc42 from the sample. The p21 binding domain (PBD) of PAK1 is expressed as a GST-fusion protein and coupled to agarose beads. After precipitation, an immunoblot is performed and the activated Rac/Cdc42 is detected with specific monoclonal antibodies, followed by HRP-conjugated secondary antibody and ECL reagent.

Biochem/physiol Actions

Species Cross-reactivity: Human and mouse. Predicted to cross-react with all mammalian species.
Anti-Rac1, clone 23A8: Species Cross-reactivity: Human, mouse and rat. Other species cross-reactivity unknown.
Anti-cdc42 Species Cross-reactivity: Human, mouse, rat and dog. Other species cross-reactivity unknown.

Preparation Note

1 year at -20°C from date of shipment

Analysis Note

Routinely evaluated by precipitating Rac1-GTP and cdc42-GTP from 3T3/A31 and HeLa cell lysates that had been loaded with GTPγS(lysates were loaded in vitro with GTPγS for cdc42-GTP). The precipitated Rac1-GTP and cdc42-GTP was detected by immunoblot analysis using anti-Rac1 (1 μg/ml).

Shaping Epigenetics Discovery - Epigenetics Product Selection Brochure

"Epigenetics describes heritable changes in gene expression caused by non-genetic mechanisms instead of by alterations in DNA sequence. These changes can be cell- or tissue-specific, and can be passed on to multiple generations. Epigenetic regulation enriches DNAbased information, allowing a cell to vary its response across diverse biological and environmental contexts. Although epigenetic mechanisms are primarily centered in the nucleus, these mechanisms can be induced by environmental signals such as hormones, nutrients, stress, and cellular damage, pointing to the involvement of cytoplasmic and extracellular factors in epigenetic regulation."

Hallmarks of Aging

"Aging: getting older, exhibiting the signs of age, the decline in the physical (and mental) well-being over time, leading to death. Since the beginning of time, man has been obsessed with trying to slow down, stop, or even reverse the signs of aging. Many have gone as far as experimenting with nutritional regimens, eccentric exercises, fantastic rituals, and naturally occurring or synthetic wonder-elements to evade the signs of normal aging. Biologically speaking, what is aging? And what does the latest research tell us about the possibility of discovering the elusive “fountain of youth”? Many advances in our understanding of aging have come from systematic scientific research, and perhaps it holds the key to immortality. Scientifically, aging can be defined as a systems-wide decline in organismal function that occurs over time. This decline occurs as a result of numerous events in the organism, and these events can be classified into nine “hallmarks” of aging, as proposed by López-Otin et al. (2013). Several of the pathologies associated with aging are a direct result of these events going to extremes and may also involve aberrant activation of proliferation signals or hyperactivity. The hallmarks of aging have been defined based on their fulfillment of specific aging related criteria, such as manifestation during normal aging, acceleration of aging if experimentally induced or aggravated, and retardation of aging if prevented or blocked, resulting in increased lifespan. The nine hallmarks of aging are genomic instability, telomere attrition, epigenetic alterations, loss of proteostasis, deregulated nutrient sensing, mitochondrial dysfunction, cellular senescence, stem cell exhaustion, and altered intercellular communication. The biological processes underlying aging are complex. By understanding the hallmarks in greater detail, we can get closer to developing intervention strategies that can make the aging process less of a decline, and more of a recline."
