The secondary parameters with regards to construct stability are visible fusion or lack thereof and signs of implant loosening, implant migration or pseudarthrosis on plain and functional radiographs.
Mouse resting Treg cells and CD4+ T cells were isolated from phosphate-buffered saline (PBS -treated FoxPBS -treatedice using Foxp3sorting based on the expression of GFP-DTR (diphtheria toxin (DT) receptor) fusion protein or lack thereof, respectively.
For transient monobody expression, 1 × 10 K562 cells were transfected with 5 μg of expression vectors encoding GFP fusion constructs of HA4-7c12 and mutants thereof using the Nucleofector Kit V (Amaxa), applying program T-016.
It's pretty much impossible, given the cold air outside, the humid, heat-producing mammals inside, and that pesky ball of fusion in the sky (or the lack thereof, depending on the time and weather).
Some of these techniques, such as FRAP (fluorescence recovery after photobleaching), TimeStamp, or derivatives thereof, make use of fluorescent fusion proteins to follow the movement or stability and synthesis of proteins in single cells (Lin and Tsien 2010; Butko et al. 2012).
Many of the lysosome-related organelles contain bulky cargoes and release thereof is often regulated during the post-fusion phase including regulation of fusion pore expansion.
As discussed in the Introduction, none of the simple models – single cue based estimation (Fig. 3a, red lines), mandatory fusion (Fig. 3b, green lines) or combination thereof – explain these particular observations.
We have observed this fusion defect in late stage 15-early stage 16 embryos to ensure that our observations and interpretation thereof are not due to a delay in fusion.
We propose that this capacitation driven membrane docking and stability thereof is a preparative step prior to the multipoint membrane fusions characteristic for the acrosome reaction induced by sperm-zona binding.
Naturally, the use of Fc-fusions as research tools when studying immune cells or extracellular proteins thereof is complicated by the ability of the Fc-domain itself to bind FcRs, as this would cause unwanted positive binding signals or biological effects.
