CYP3A4 is an important member of the cytochrome P45 enzyme superfamily, with 33 alleles. Human cytochrome P45 3A4 (CYP3A4) is an important drug metabolism enzyme involved in many drug-drug and food-drug interactions. Systemic inflammation is associated with inhibition of CYP3A4 activity.

Animal A (mg/kg) = Animal B (mg/kg) multiplied by | Animal B Km |

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.

Recombinant Human Tau-F Protein (E.coli)
Tau proteins are proteins which contain four Tau/MAP repeats. They promote microtubule assembly and stability, and might be involved in the establishment and maintenance of neuronal polarity. |
Recombinant Human Tau Protein (E. coli, His Tag)
Tau proteins are proteins that stabilize microtubules. Tau protein is a highly soluble microtubule-associated protein (MAP). In humans, these proteins are mostly found in neurons compared to non-neuronal cells. One of tau's main functions is to modulate the stability of axonal microtubules. |
