The phrase "a much greater affinity" is correct and usable in written English.
It can be used when comparing the strength of a connection or relationship between two entities, indicating that one has a significantly stronger bond than the other.
Example: "The study revealed that participants had a much greater affinity for visual learning compared to auditory learning."
Alternatives: "a significantly stronger connection" or "a far deeper bond".
Hemoglobin, the oxygen-carrying substance in blood, has a much greater affinity for carbon monoxide than it has for oxygen, and together they form a stable compound, carboxyhemoglobin, that decreases the amount of uncombined hemoglobin available for oxygen transport.
Dr. Bill Chambers, a Senior Vice President of ACS, said in a press release, "We suspect that some millennials...may feel a much greater affinity for supporting researchers from their ranks.
It is noteworthy that BSF and HSA that had been trapped by precipitating minerals gave similar intensities when analyzed by SDS-PAGE in spite of a 10-fold difference in their concentrations used, indicating again a much greater affinity of these mineral complexes for fetuin-A as compared to albumin (see Fig. 21 of ref. [2]).
However, other studies indicate that cancer cells have a much greater affinity for the peritoneal ECM, which is consistent with the clinical pattern of metastatic spread.
The P509S variant exhibited a much greater affinity for J-proteins when compared with wild-type, further validating the observed excessive stimulation of the ATPase activity (Figs 1B and 2A).
PseB binds UDP-GlcNAc with a much greater affinity (140-fold lower Km) with respect to the diNAcBac biosynthesis enzyme, PglF, resulting in a higher catalytic efficiency (31-fold).
A target sequence that perfectly matches the sequence of a probe binds with much greater affinity than one with a mismatch sequence.
Biochemically, the two isoforms appear to operate in a similar manner; they have indistinguishable activities in an in vitro translation system, but eEF1A2 shows much greater affinity for GDP than GTP, whereas eEF1A1 has a greater affinity for GTP [ 4].
CysLT1 binds LTD4 with much greater affinity than either LTC4 or LTE4 [ 11]; in contrast, CysLT2 binds LTC4=LTD4>LTE4.
Because of the much greater affinity of the C4F6 antibody for the G93A protein, we cannot be sure whether the immunoreactivity detected in these mice is indicative of conformational change.
A much greater adsorption affinity of PAA chains to the SA-96 surface is mainly due to the favorable attractive interactions which are present in the system at the pH range below pHpzc (namely at pH <7.6).
