A cell seeding plate comprises a substrate and a photolysis layer formed on a surface of the substrate. The photolysis layer comprises a plurality of photolysis groups, and each of the plurality of photolysis groups has a chemical structural formula of

##STR00001##

R.sub.1 and R.sub.3 each represents alkane group, R.sub.2 comprises alkane group or olefin group, R.sub.5, R.sub.6 and R.sub.7 each represents hydrogen group or alkane group. Each of the plurality of photolysis groups is bonded to the surface by the amide group.

A fiber reaction process whereby reactive components contained in immiscible streams are brought into contact to effect chemical reactions and separations. The conduit reactor utilized contains wettable fibers onto which one stream is substantially constrained and a second stream is flowed over to continuously create a new interface there between to efficiently bring about contact of the reactive species and thus promote reactions thereof or extractions thereby. Co-solvents and phase transfer catalysts may be employed to facilitate the process.

A novel agent for introducing a protecting group for a hydroxy group and/or a mercapto group that can be introduced and removed under mild conditions is provided. The agent for introducing a protecting group for a hydroxy group and/or mercapto group of a substrate compound having the hydroxy group and/or mercapto group is represented by the following formula (I), wherein A represents a ring structure having 1 to 5 rings in which two carbon atoms of an adjacent benzene ring are included, the ring structure comprises a substituted or unsubstituted five-membered ring or six-membered ring and optionally include a heterocycle; each of R.sup.1, R.sup.2, R.sup.3, and R.sup.4 is independently a hydrogen atom or a linear or branched alkyl group having 1 to 5 carbon atoms; and X is a halogen atom or OSO.sub.2R.sup.5 (R.sup.5=an aryl group or an alkyl group).

An apparatus includes a conduit with two process fluid inlets at one end of the conduit, one process fluid outlet at an opposing end, a heat exchange medium inlet, and a heat exchange medium outlet. One of the fluid inlets includes a tube extending into the conduit and a perforated node at the end of the tube, and the other of the fluid inlets is arranged up stream of the perforated node. The apparatus further includes hollow tubes positioned longitudinally within the conduit between the two process fluid inlets, the process fluid outlet, the heat exchange medium inlet and the heat exchange medium outlet. In addition, the apparatus includes a collection vessel positioned proximate the fluid outlet and fibers extending through each of the hollow tubes, wherein one end of the fibers is secured to the perforated node and the other end of the fibers extends into the collection vessel.
