The phrase "attachment required" is correct and usable in written English.
It is typically used in contexts such as emails or documents to indicate that a file or document must be included with the message.
Example: "Please submit your application form by the deadline; attachment required."
Alternatives: "file needed" or "document necessary".
We have previously reported that primary Schwann cells expressing the SV40 Large T antigen (LT) are not fully transformed in that they maintain a strict requirement for attachment, requiring a further genetic change, such as oncogenic Ras, to gain anchorage-independence.
Full understanding of the mechanism of initial attachment requires further study, but may be related to QD charging (electrostatic attraction to induced charges); however, once contact is made, Van-der-Waals forces and insolubility of the QDs in the electrolyte are likely to be the primary reasons for their robust and prolonged attachment to the mp-TiO2.
More detailed information on the separation of the primary energy minimum from the secondary energy minimum and the reversible portion of bacterial attachment requires a careful design of breakthrough experiment for a given bacterium and porous medium.
This attachment requires pyruvylation of the cell wall by the protein CsaB [ 19], which is encoded on the chromosome (ATCC9714_28031).
This combination has been used to explore whether fibroblast attachment requires a minimum number of RGD peptides per cluster (minimum local concentration) and whether spacing within and between clusters can also affect adhesion [ 53].
Another advantage of this approach is that the display indicates any additional forms and attachments required by the announcement.
At the equator PEFs become critical to stabilize end-on kinetochore-microtubule attachments required for chromosome bi-orientation (Barisic et al., 2014, Magidson et al., 2011, Wandke et al., 2012).
After chromosome bi-orientation, the opposing spindle forces generate tension on centromeres that is important for the stabilization of correct kinetochore microtubule attachments required for error-free chromosome segregation (Nicklas and Koch, 1969, Nicklas and Ward, 1994).
Photo attachments require huge gobs of bandwidth compared with ordinary e-mail.
