Biochemical and physiochemical characteristics of a pre-B cell stimulating factor produced by the plasmacytoma cell line LICR LON HMY2

We have characterized the pre-B cell colony stimulating activity (pre-B cell CSA) from LICR LON HMY2 conditioned medium (CM) by a variety of biochemical techniques. Pre-B cell CSA was found to be associated with a heat stable glycoprotein which has an isoelectric point of 8.3 and a mol. wt, as determined by polyacrylamide gel electrophoresis, of 28-32 kD. The relationship of this activity to previously described factors acting on cells of the B cell lineage is discussed.

Chan ceist duit a bhás go bráth: 'An Lon Dubh Báite'

This article discusses an enigmatic poem by the 18th century Gaelic poet Séamas Mac Cuarta, and three subsequent translations into English. The poem is written in the 'Trí Rann agus Amhrán' form, reminiscent of the English sonnet.
