Following binding of an EGF ligand, the rate of endocytosis of HER1 is increased about tenfold, and only a fraction of the internalized receptors return to the plasma membrane; the rest are degraded in lysosomes.

The probe must span the sequence where the transcript starts or ends. After hybridizing the probe to the transcript, one applies S1 nuclease, which degrades only single-stranded DNA and RNA.

In resting state,  the activation loop is not phosphorylated and assumes a conformation that blocks kinase activity.

In insulin receptor, it prevents binding of ATP. 

In FGF receptor, it prevents binding of substrate.

The time of sedimentation (in seconds) for a spherical particle is (Please see the picture below)
where t is the sedimentation time, is the viscosity of medium, R hydro is the
hydrodynamic radius of the particle, r b is the radial distance from the centre of rotation
to bottom of tube, r t is the radial distance from the centre of rotation to liquid meniscus,
ρ is the density of the particle, m is the density of the medium and is the angular velocity
of the rotor.
