The degree of internalization should amount to 100%.
At 37°C, a temperature that allows energy-dependent TTR internalization, the total amount of T119M TTR interacting with the cells increases compared with the incubations performed at 4°C.
Internalization of large amount of PHLG-TEP was observed for incubation as short as 30 min, demonstrating its potent membrane permeability.
Notably, although internalization of total β1 integrin was not significantly impaired in either si hR-Ras or si hRIN2 ECs, knockdown of either R-Ras or RIN2 selectively reduced the amount of active (9EG7-positive) β1 integrin endocytosed by ECs.
The subcellular distribution was assessed to determine the internalization pathway and the amount of radioactivity stored in the nuclei after 2, 4, and 24 h of continuous incubation of pancreatic tumor cells with [Lys40(Ahx-DTPA-111In NH2]-exendin-4.
Fluorescence microscopy study shows the higher amount of internalization of the noncomplex by KB cells, which clearly demonstrated that cells overexpressing the human folate receptor internalized a higher level of these nanoparticles folate conjugates than folate receptor-negative control cells.
Over expression of exogenous wide-type p85α did not increase spore internalization, possibly because the amount of endogenous adaptors was sufficient to mediate spore internalization (Fig. 2, E and Fig. S1, D).
In addition, proheparanase and heparanase activity accelerate syndecan internalization, possibly enhancing the amount of endosomal syndecan (Supplementary information, Figure S6).
The amount and internalization of NK-1 receptors on SCDH neuron densities increased after peripheral inflammation [ 33], and induced mechanical allodynia in several inflammatory pain models [ 34, 35].
