Formula, Inline


A mathematical equation, expression, or formula that is to be displayed inline. The mathematics itself can be expressed as ASCII characters, as a graphic, or using TeX, LaTeX, or MathML mathematics expressions.


Some print-oriented DTDs use a specific element to indicate “go into math mode or math font here”; while that was not the intended usage of this element, in nearly all cases the text inside such math-changes is a mathematical expression and it would not be incorrect to use this element to mark such material.

<p>EM4 cells, stably transfected with Flag-HA-DAT, Myc-His-DAT,
or both, were reacted with cross-linker and solubilized in Triton X-100
as above. There is no reason to have this formula, 
</inline-formula> here. Five microliters of anti-Myc 9E10 (Santa Cruz 
Biotechnology) was added to 0.2 ml of Triton X-100 extracts, and the 
mixture was incubated for 1 h at 4&#x00B0;C. Twenty microliters of 
rec-protein G Sepharose (Zymed) was added, and the mixture was incubated 
for 1 h at 4&#x00B0;C, washed three times in 0.5 ml of lysis buffer, 
and eluted in 45 &#x03BC;l of 2&#x00D7; Laemmli sample buffer without 
reducing agent.</p>
