This article is devoted to the use in concrete of polymeric reagent POLY-ANS, developed based on production waste polyacrylonitrile fibers. The results effect capillary absorption concrete, which contributes provision high resistance cement saline environments, are given.

Here we report a modified peptide reagent useful for the rapid, native elution of protein complexes containing a Protein-A-tagged component. We tested this reagent for the elution of tagged endogenous protein complexes from yeast (Nup53p/Nup170p dimer; Nup1p/Kap95p/Kap60p trimer; pentameric GINS complex) and bacteria (RNAP holoenzyme). The majority of the affinity-isolated material is released ...

A modified toluidine blue O (TBO) stain for Pneumocystis carinii cysts was evaluated with regard to the influence of (i) the age and extent of use of the sulfation reagent, (ii) the source of TBO, (iii) the TBO content of the staining solution, and (iv) the amount of TBO present in the alcohol wash solutions. All TBOs evaluated, except for a new TBO obtained from Roboz Surgical Instrument Co., ...
