    摘要: Lymphotoxin (LT) mutein (genetically-altered LT) is disclosed that has the following amino acid sequence, or a portion of an active portion of said protein, where 10 to 21 amino acids of LT being deleted from N-terminus and which has Pro or Phe at the N-terminus: ##STR1## Wherein R.sub.1 is Pro or Phe, R.sub.2 is a peptide chain represented by the following sequence:Ala-Gln-Thr-Ala-Arg-Gln-His-Pro-Lys-Met-His-Leu,or a portion thereof and n is 0 or 1.The LT mutein can be recovered in a higher yield and purified more efficiently under mild conditions which does not harm the LT's biological activity, than the whole LT.

    摘要: When an optical waveguide is formed by focused femtosecond laser pulses in a pure silica glass to induce a refractive index increase region, a pulse width of femtosecond laser pulses are changed, a peak power of femtosecond laser pulses at the focal point is changed, or both the pulse width and the peak power are changed simultaneously. Under conditions where a pulse width of the femtosecond laser pulses is in a range of 210 to 420 fs and a peak power at the focal point is not greater than 8.7×1011 W/cm2, an optical waveguide having a mode field of 10 to 14 μm such that an aspect ratio is 1 (one) can be obtained. By doing this, it is possible to control a mode field diameter of an optical waveguide and an aspect ratio of the mode field diameter.
