S mg), dimer (peak I) and monomer (peak 2), ovalbumin (S mg) (peak 3), and cytochrome c (3 mg) (peak 4) was loaded onto a Fractogel EMD BioSEC column (600 X 16 mm) with a bed height of 600 mm. PBS (pH 7.2) was used as the eluent at a flow rate of I ml/min the sample volume was O.S ml. (B) The same protein sample as in A was injected onto a column of identical dimensions packed with unmodified Fractogel HW 6S. Without the tentacle modification the base matrix displays only a poor resolution of the test mixture.

Compared with conventional type, the tentacle type exhibits a marked increase in selectivity. The results observed for preparative ion exchangers of tentacle type prompted the author to test this structural arrangement of the binding groups also for analytical materials based on porous silica. Figure 12 reveals that the tentacle-specific selectivity is fully preserved when the matrix is changed.

The symmetric series provides functional cyclohexadienes, whereas the non-symmetric one serves to build deuterated and/or functional arenes and tentacled compounds. In both series, several oxidation states can be used as precursors and provide different types of activation. The complexes bearing a number of valence, electrons over 18 react primarily by electron-transfer (ET). The ability of the sandwich structure to stabilize several oxidation states [21] also allows us to use them as ET reagents in stoichiometric and catalytic ET processes [18, 21, 22]. The last well-developed type of reactions is the nucleophilic substitution of one or two chlorine atoms in the FeCp+ complexes of mono- and o-dichlorobenzene. This chemistry is at least as rich as with the Cr(CO)3 activating group and more facile since FeCp+ activator is stronger than Cr(CO) 3. 

Actinia cari. When an extract of the tentacles of this species was subjected to gel nitration, a single protein peak having hemolytic and lethal activities was obtained. Further fractionation by CM-cellulose ion-exchange chromatography yielded three well separated peaks (CTl, Cmi, Cmil) which appeared to be similar in biological activity (14). 

Pain production is the most common injury inflicted on man. This noxious stimulus is perceived almost instantly after skin - tentacle contact.

Drosera rotundifolia L., or round leaf sundew, is a little perennial herb that can reach 35 cm in height. The plant is found in temperate bogs and swampy areas. The leaves are simple, fleshy, broadly ovate and arranged into rosettes. The leaves are covered with sticky, shiney, red tentacles. The flowers are pink (Fig. 23). 

The cyclopentadienes la-e can be deprotonated by potassium in toluene to give the potassium cyclopentadienides 2a-e [2]. These compounds are very soluble in THF and also in hot benzene or toluene, which is indicative of the presence of essentially monomeric units in solution this is due to an intramolecular donor stabilization by the tentacle function [6]. 

Zinc normally aids wound healing in terrestrial invertebrates. Wounding of the optic tentacle, foot tissue, and partial shell removal in Helix aspersa, a terrestrial gastropod, resulted in deposition of zinc in the wound area after 2 to 5 days. Increased zinc in Helix wound areas may be necessary to promote protein synthesis, collagen formation, and mitotic cell division (Ireland 1986).
