The phrase "we further required" is grammatically correct and can be used in written English.

At these positions, we further required that the derived alleles have frequencies between 5 and 15% in the human populations to minimize the influence of variants potentially under positive selection or balancing selection.
We further required the presence of 250 base pairs on either side of the putative SNP in FV-1 to avoid potential poor quality SNPs at contig ends.
To retroactively measure the progress of human genome annotation, we further required a gene annotation source providing access to releases over a multi-year period.
We further required that 250 base pairs on either side of the putative SNP in the FV-1 sequence be present (to avoid SNPs at the ends of contigs where sequence quality tends to be poor).
We further required compatible chest imaging documenting an infiltrate(s).
We further require that the BMP receptor diffuses about 100-fold more slowly than the BMP protein.
We further require that students register their travel plans in the Cornell Travel Registry and print out a UnitedHealthcare Global (UHG IDD insurance card.
We further require that biochar be manufactured using modern technology that eliminates soot, CH4 and N2O emissions while recovering some of the energy released during the pyrolysis process for subsequent use.
We further require a briefing on all investigative findings, as these matters directly impact the core factors in our deliberations of whether Mr. Trump is fit to serve as president of the United States.
We further require that BMP diffuses about 2.7-fold faster than FGF which brings the BMP diffusion constant close to the diffusion constant D ~ 100 μm2 s−1 that is typically measured for soluble proteins87 unless diffusion is impeded by adsorption to the surface86.
