The phrase "as a weak background" is correct and usable in written English.
It can be used to describe a context or situation that lacks strength or support, often in discussions about arguments, evidence, or settings.
Example: "The author's argument was unconvincing, relying on as a weak background that failed to support the main thesis."
Alternatives: "as a flimsy foundation" or "as a poor basis".
As shown, 2.0% Karnovsky's fixative (2% paraformaldehyde plus 2% glutaraldehyde) applied for 90 min at 4°C, produced the highest positive fluorescence with a weak background staining as compared to the other fixatives.
This constitutes possibly the most prominent weakness of the available studies in PBC genetics, as the candidate genes were often chosen based on a weak background.
"I was called a right-winger, but I said we are letting children down who have a weak background".
Control animals treated with PBS that were stained equally showed a weak background staining for both treatment groups (Fig. 2 L and N), but the staining for 22C4 scFv was much stronger as compared to the negative control.
As it is seen from Fig. 3a, the behavior of the SiO2 C sample annealed at 800 °C is essentially different from that for other samples the PL appeared just as a very weak background and the D and G features typical of carbon were observed.
However, other possible mechanisms, such as weak background selection or chance alone, could also explain fast-running for some human SNPs.
The images clearly show the fluorescence outline around the embryos and a very weak background signal.
Two bands of 42 and 31 kDa were visualized over a very weak background (Fig. 5A).
Generally, a weak laser background contribution is not relevant for the acquisition of single molecule signals, since this simply adds a constant background, as long as laser power fluctuations are not too large.
Those who decide the world's economic fate typically have a weak scientific background or none at all.
