"surface expression levels" is a correct and usable phrase in written English.
It is typically used in scientific or technical writing to describe the amount or intensity of a certain characteristic or marker on the surface of an object. Example: The researchers observed a significant decrease in surface expression levels of the cancer biomarker in the treated group compared to the control group.
S. aureus 8325.4-derived ΔfnbA/B expressing fnbA variants from a plasmid have been characterised previously [17] to establish equal surface expression levels between strains expressing each construct.
For example, 54 Nt_BRIL and 65 Iconstructsonstructs had surface expression levels >80%, yet only 22 receptors expressed at this level for both constructs (Tables S2 S4).
The cells were then washed and analysed by flow cytometry using 488-nm laser for detecting surface expression levels.
DnaK-treated Mo-DCs had lower HLA-DR (MHC II) surface expression levels (Fig. 7a), higher MARCH1 and IL-10 mRNA levels (Fig. 7b).
Interestingly, both Cav-1 and CHC knock-down slightly increased total and cell surface expression levels of PrPC (Fig. 1f, g).
After transfection, cells were stained for MHC I surface expression levels using PE-conjugated anti-MHC I mAb (W6/32, AbD Serotec) and sorted on a FACSAriaII (BD Biosciences).
In vitro functionality and surface expression levels of all three CARs was greater in BALB/c T cells than C57BL/6 T cells, indicating strain-specific differences.
The majority of Nt_BRIL constructs (424) had surface expression levels between 30%60%%, while most of ICL3_BRIL constructs (390) had surface expression levels between 10%40%%.
(A) Surface expression levels of CD29, CD45, CD54, and CD90 were analyzed by flow cytometry.
We characterized the differential cell surface expression levels of all common HLA-C allotypes and tested directly for effects of HLA-C expression on outcomes of HIV infection in 5243 individuals.
The surface expression levels of HLA-1 remained unchanged for the remaining experimental groups.
