The phrase "assays for the quantification" is correct and usable in written English.
It can be used in scientific or technical contexts where you are discussing methods or tests used to measure or quantify a specific substance or characteristic.
Example: "The laboratory conducted several assays for the quantification of protein levels in the samples."
Alternatives: "tests for measurement" or "analyses for quantification".
The HPLC assays for the quantification of ertapenem in biological matrices reported so far are based on columns of 4.6 mm I.D. and involve pre-concentration by use of column-switching.
Specific qPCR assays for the quantification of DNA viruses have been proposed as specific and sensitive assays to quantify human, porcine, bovine polyomavirus, poultry, and ovine fecal contamination in environmental samples.
Our group recently developed quantitative PCR (qPCR) assays for the quantification of chicken/turkey parvoviruses and ovine polyomaviruses which, together with those previously proposed for human, bovine and porcine fecal contamination, might constitute a tool box for studying the presence and origin of fecal contamination in environmental samples (Table 1).
Consequently, we designed NASBA-based assays for the quantification of the mRNA encoding two members of the CC-chemokine family: RANTES and MIP-1β.
There is a growing list of commercially available, ready-to-use, multiplexed bead-based assays for the quantification of cytokines and cell-signaling molecules and the analysis of kinase activity (www.biochipnet.de, Biochipnet).
Using published PCR primers for F. verticillioides [ 25] and F. proliferatum [ 26], we developed qPCR assays for the quantification of the DNA of these species in maize kernels.
Here we describe the development of rapid, sensitive, and specific real-time PCR assays for the detection and quantification of MmmSC and Mccp DNA.
Although the functionality of these factors resides in their protein forms, assays for the detection and quantification of these protein factors in clinical samples are not readily available.
Gene expression assays for the detection and quantification of FOXP3 (Hs00174114_m1) and the housekeeping gene glyceraldehyde 3-phosphate dehydrogenase (GAPDH) were purchased from Applied Biosystems and used according to the manufacturer's protocol.
Samples were then subjected to taxon-directed 16S rRNA gene qPCR assays for the detection and quantification of L. crispatus and L. jensenii.
An additional important outcome of this study is the provision of a standard reference serum that can be used in a variety of serologic assays for the detection and quantification of anti-PA antibodies.
