Specific antibodies that block homophilic N-CAM binding labeled the distal ends of the branches of the ld/sd rosettes and the ends of the longer arm of both the ssd chain and the Fr2 fragment.
For example, exposure of certain colon cancer cell lines (e.g. Caco-2) to the most avidly binding labeled peptide, MA5, for a two-hour period resulted in the transfer of a radioactive dose of over 29 counts per minute per cell after a two hour incubation, wash, and immediate determination of the retained radioactivity.
cNonfluorescent quencher dye (MGB™; minor groove binding) labeled nucleotide.
Although as one with no binding label or group associations, her status teeters on a free agent in the industry.
Further suggesting that Meis/Hoxa2 synergistic binding labels IIBA long-range enhancers, insertions of a reporter gene in topologically associated domains (Chen et al., 2013; Dixon et al., 2012), which contain Hoxa2/Meis synergistic binding, highlighted the presence of regulatory domains of IIBA-specific expression.
However, specificity concerns may also be compounded if sense probes used as negative controls for antisense probe binding label the tissue of interest (one definition of 'non-specific' hybridization), which is not implausible since over 50% of the mammalian genome can produce transcripts from both DNA strands [155].
For this, cells were treated with the indicated concentrations of aspirin or curcumin for 4 h, the nuclear extracts were prepared, and the extracts examined for binding to labeled oligonucleotides containing specific binding sites for Oct-1 by EMSA.
A large excess (200-fold) of non-specific DNA (pGEM®-T DNA) was unable to compete with PhilD for Fur·Mn2+ binding, whereas an excess of non-labeled PhilD DNA fully competed for binding with labeled PhilD DNA (Figure 1D).
Dye-NHS modification of streptavidin severely damaged ligand binding, necessitating development of a new streptavidin-retaining ultrastable binding after labeling.
This study found that the hybridization kinetics for specific and non-specific binding of labeled cRNA to surface-bound oligodeoxyribonucleotides were significantly different, with specific binding requiring longer to reach hybridization equilibrium than non-specific binding.
The TCII-OLEO transfected cells had a dramatically higher binding with labeled B12 in the membrane fraction, compared with other transfected cells, when 57Co-labeled Cobalamin was incorporated into culture medium for three days (Fig. 1C).
