The phrase "assayed in media of" is correct and usable in written English.
It can be used in scientific or technical contexts, particularly in reference to testing or analyzing substances in specific media or environments.
Example: "The samples were assayed in media of varying pH levels to determine their stability."
Alternatives: "tested in environments of" or "analyzed in conditions of".
LDH release was assayed in media from each of the four indicated conditions at 4 and 24 h, relative to the amount of LDH released from cells induced to undergo necrotic death by three freeze/thaw cycles.
Protein levels of MMPs were assayed in conditioned media by gelatin and casein zymography.
On day 21, secreted hexosaminidase activity was assayed in 0.5 mL media by addition of 125 µL 5 X hexosaminidase substrate buffer (0.5 M sodium acetate pH 4.4, 0.5% Triton-X-100, 5 mM p-nitrophenyl N-acetyl-β-D-glucosaminide).
Eight hours after the addition of IGF-1, MMP activity was assayed in the conditioned media.
The sensitivity of biosensor assays in complex media such as plasma or serum is often limited by non-specific binding.
The growth of the qns1 strain is then assayed in a 1∶1 mixture of conditioned media and fresh 2x SDC such that the extent of qns1 growth is proportional to the extracellular concentration of NR.
Activity of the comK promoter was assayed in the two-step competence media.
Samples of media were collected at 24, 48, 72 and 96 h post-infection and assayed in triplicate for progeny virus by plaque assay using CK cells.
The effects of HB-EGF on cetuximab resistance were further examined by colony formation assays in serum-free media.
Assays with PHO5 -lacZ in media depleted of phosphate, and HIS4 -lacZ in media lacking histidine were performed as described in Mutiu et al. (2007), GAL10 -lacZ in media containing 2% galactose as the carbon source in Brandl et al. (1993), and for RPL35a-lacZ in YPD as described by Hoke et al. (2010).
