`of immobilization of high-molecular-weight
`The efficiency
`RNA on aminated
`silica carriers
`has been studied
`[ 449]. More
`than 90% of the RNA added was bound
`to the carrier
`in undegrad(cid:173)
`ed form. The procedure
`allows us to link as much as 2. 0 mg of
`RNA per gram of carrier.
`During nucleic acid hybridization
`( 65°C, 2 x SSC) in the presence
`of trace amounts of pronase,
`chipping
`off of RNA was observed
`only during
`the first 6 hr of
`incubation.
`More than half of the immobilized poly(A) RNA re(cid:173)
`mained
`tig·htly bound
`to the carrier.
`The immobilized messenger
`and ribosomal yeast RN As were hybridized
`with total yeast
`[ 1251]
`DNA. Several methods
`for the immobilization
`of polyribonucleo(cid:173)
`tides
`take advantage
`of the vicinal diol groups present
`or poten(cid:173)
`tially present
`in polyribonucleotides.

`mary amino groups of AE-cellulose
`( Scheme 16). The unstable
`Schiff bases can be converted
`to stable
`structures
`by reduction
`The binding
`using NaBH 4 [8,103-105],
`in these products
`is
`ring
`thought
`to arise from the formation of a substituted morpholine
`structure
`that
`includes
`the nitrogen
`of the AE-cellulose
`and the
`five atoms
`that orig·inally constituted
`the ribose
`ring of the ter(cid:173)
`minal nucleoside.
`The assignment
`of this
`linkage
`is based on the
`of the produ-ct obtained
`from the borohydride

`of the complex
`formed between periodate-oxidized

`a mixture of agar and poly(cid:173)
`acrylic
`acid hydrazide
`has been used
`in this way to immobilize
`tRNA [107].
`Periodate-oxidized
`mRNA has been coupled
`to a lin(cid:173)
`ear polymer of acrylic hydrazide
`entrapped
`in agar
`[ 108] . The
`reduction with NaBH 4 has also been used
`to stabilize
`the linkage
`in a similar complex obtained
`from periodate-oxidized
`tRNA and
`hydrazinyl-Sepharose

`As a result
`of attachment
`of periodate-oxidized
`coli tRNA to these
`Escherichia
`materials,
`preparations
`were obtained having as many as 100- 900
`Az60 units per gram of sorbent.
`To avoid nonspecific

`that might arise due to excess aminopropyl
`groups,
`the prepara(cid:173)
`tions of immobilized nucleic acids were treated with acetic anhy(cid:173)
`dride,
`The supports with immobilized
`tRNA thus obtained were
`shown
`to be almost completely
`inert with respect
`to heterological
`DNA [ 111].

`Similar complex form(cid:173)
`ation can be observed
`on dihydroxylboryl-substituted
`methacrylic
`acid-polymer
`(borate
`gel)
`[ 119].
`It should be pointed out that
`from its chemical constitution,
`the borate gel appears
`to be more
`resistant
`than
`the borate-substituted
`cellulose
`to degradation
`by
`heat or by microorganisms.
`Moreover,
`these gels are suitable
`for
`chromatography
`under pressure,
`which is advantageous
`for pre(cid:173)
`parative
`separations.
`The uses of boronic acids
`immobilized
`to
`insoluble
`supports
`include
`separating
`ribonucleotides
`from deoxy(cid:173)
`ribonucleotides
`[119,120],
`isolating
`3'-terminal
`polynucleotide
`fragments
`from large RN As [ 121], and separating
`3'-modified
`polynucleotides
`from unmodified ones
`[ 122] .
`Immobilized boronic
`acid can also be used
`to separate
`aminoacyl-tRNA
`from unacylated
`species
`[116,119,123-125].

`Using dihydroxyboryl
`cleotides of the in vitro T3 RNA polymerase
`transcript
`has been iso(cid:173)
`lated
`[ 126] . The advantages
`and disadvantages
`of several bor(cid:173)
`onate-containing
`supports
`have been
`investigated
`[ 127] , with the
`following
`results.
`Boronate
`cellulose binds macromolecular RNA
`but often
`is not useful
`for trace amounts of material because of
`nonspecific
`adsorption.
`It was found
`that boronate polyacryla(cid:173)
`mide and boronate
`agarose both display very
`low levels of non(cid:173)
`specific adsorption.
`Boronate polyacrylamide
`specifically
`binds
`cis-diol-containing
`mononucleotides
`or short oligonucleotides,
`but
`does not retain polyribonucleotides
`sufficiently
`tenaciously
`for
`preparative
`use. Boronate
`agarose proved
`to be suitable
`for the
`fractionization
`of trace amounts of macromolecular RNA, but not
`for mononucleotides.
