The phrase "are required for generation" is correct and usable in written English.
It can be used in contexts where you need to indicate that certain elements or conditions are necessary for the process of generation, such as in scientific, technical, or instructional writing.
Example: "The following materials are required for generation of the energy needed to power the device."
Alternatives: "are necessary for creation" or "are essential for production".
The TNF family member B cell activating factor (BAFF, also known as BLyS) and its cognate receptor BAFF-R are required for generation and maintenance of the mature B cell pool [20], [21], [22].
In the well-accepted mechanism for dioxygen activation in P450 monooxygenases, two protons (and two electrons from NADPH) are required for generation of Compound I [ 27].
Th1-like responses include IL-2, TNF- α, and IFN- γ secretion and are required for generation of cytotoxic T lymphocytes and NK cell activation during the host antiviral immune response.
However, it has recently been shown that DNA-PKcs and ATM, a major upstream activator of p53, are required for generation of a bystander signal, but not for response to that signal [ 4].
Although low levels of endogenous mouse HoxB4 expression were detected in c-Kit+CD41+ cells, higher expression levels might be required for generation of HSCs.
Each of the serine phosphoacceptor sites is required for generation of rcDNA, although serine 162 is the most important and serine 155 is the least important of the three.
Based on their ability to visualize particles, Liu et. al. concluded that only N and the envelope glycoproteins were required for generation of particles, however efficiency of release could not be determined using their methods [38].
Our findings demonstrate that LGP2, though not essential, is required for generation of optimal cytokine responses to intracellular dsDNA, infection with the bacterium Listeria monocytogenes (LM) and the pox virus, modified vaccinia virus Ankara (MVA).
Thus, given that the redistribution pattern of Vav was reminiscent of other signaling molecules implicated in microcluster formation [4], and that Vav colocalized with SLP-76, these data suggest that Vav could be involved at the sites of initial TCR-induced actin polymerization, which is consistent with our finding that Vav is required for generation of F-actin and cell spreading (Fig. 1).
These results indicate that Pak2 is required for generation or homeostasis of peripheral T cells.
NWASP-syndapin interaction may be required for generation of ROBO4-labeled vesicles and endocytosis [ 66].
