2. Cytology (now chiefly Historical). [ < German linin (F. Schwarz 1887, in Beitr. z. Biol. d. Pflanzen V. 9), < Greek λίνον (= Latin līnum) thread.] A substance which composes the fine threads seen in interphase nuclei; a thread or network composed of this substance (see quot. 1932).

1887 Jrnl. Royal Microsc. Soc. 7 979 As components of the nucleus, Schwartz [sic] distinguishes the following substances:—..(3) linin and paralinin, the substance respectively of the nuclear threads, the ‘nucleo-hyaloplasm’ of Strasburger, and of the intermediate matrix or ‘nuclear sap’.
1901 Trans. Royal Irish Acad. 1896–1901 30 665 The nucleo-hyalo-plasma, which, for brevity, we may call by Schwartz's term adopted by Strasburger, linin.
1905 Rep. Brit. Assoc. Advancem. Sci. 567 The nucleus contains an achromatic network—the linin—in which the chromatin granules are embedded.
1910 Encycl. Brit. VII. 716/2 The chromatin, becoming metabolically active, flows out on to the linin reticulum.
1923 F. O. Bower Bot. Living Plant 531 The resting nucleus of a vegetative cell has a reticulate structure. The network is recognised chiefly by the punctuated appearance of the anastomizing threads. These threads consist of a substance called linin, which bears minute granules of chromatin.
1925 E. B. Wilson Cell (ed. 3) i. 88 The [nuclear] framework itself appears to consist of two constituents, namely, a continuous ‘achromatic’ basis, and of more or less discontinuous granules or clumps of ‘chromatin’ suspended in it... The first of these was found to be oxyphilic and was accordingly designated by Strasburger as nucleohyaloplasm, by Carnoy as the plasmatic network (composed of ‘plastin’) and later by Schwarz ('87) as linin, a term still in common use.
1932 C. D. Darlington Rec. Adv. in Cytol. 498 Linin, a structural component of the nucleus. The term has been applied to the descriptions of various artefacts and has no definite meaning.
1948 W. Andrew tr. E. D. P. de Robertis Gen. Cytol. vii. 137 A fine lightly staining reticulum, the linin.
1969 W. V. Brown & E. M. Bertke Textbk. Cytol. 574/1 Linin, achromatic material connecting chromioles in the interphase nucleus, in contrast to only one substance, karyotin, composing the reticulum.
