The phrase "alter the reactivity" is correct and usable in written English.
It can be used in contexts related to chemistry, biology, or any field where the reactivity of substances or systems is being modified or changed.
Example: "The researchers aimed to alter the reactivity of the catalyst to improve the efficiency of the chemical reaction."
Alternatives: "change the reactivity" or "modify the reactivity".
Replacement of heme in an enzyme with a nonnatural metalloporphyrinoid can significantly alter the reactivity of the enzyme.
These results are interesting with respect to recent research showing that changes in neurotransmitter signalling may alter the reactivity of brain-controlled immunoregulatory systems controlling pathogenic microorganisms colonizing mucosal surfaces.
We have shown that fusions to different CBMs can alter the reactivity with four different polysaccharides.
It is also possible to alter the reactivity of the glycosyl donor by varying the size of the anomeric protecting group.
To test the hypothesis that reduced λ5 expression was sufficient to alter the reactivity of new B cells with PC, bone marrow B cells from young adult λ5 KO mice were cultured with LPS and anti-PC ASC determined.
To assess this, ovine PrP secondary structural changes induced by Cu2+ treatment were analysed by ELISA using anti-PrP monoclonal antibodies as shown in Figure 4. Treatment with either 0.2 or 2 mM Cu2+, reduced the reactivity of ALRQ PrP with the N-terminal specific anti-PrP monoclonal antibody FH11 by >50%) but did not alter the reactivity of ALHQ).
Work leading up to this proposed mechanism4 involved site-directed mutagenesis in tobacco, which had the aim of destabilizing the enzyme active site and altering the reactivity of the enediol intermediate.
The EDIII substitutions examined primarily altered the reactivity of DENV complex MAbs (Table 2).
The electrostatic properties of helix macrodipoles have previously been implicated in altering the reactivity (significantly reducing the pKa) of cysteine residues positioned at the N-termini of α-helices [30].
Regarding this hypothesis it is worthwhile of note that the binding of substrates to affinity sites located inside AcrB in Haemophilus influenzae induces noticeable conformational change altering the reactivity of specific residues [25].
It is proposed that CRP mediates protection from nephritis in SLE by the induction of anti-inflammatory cytokines and altering the reactivity of macrophages to inflammatory stimuli.
