Thermo Scientific Pierce Sulfo-SMPB is a water-soluble amine-to-sulfhydryl crosslinker that contains NHS-ester and maleimide reactive groups at opposite ends of a medium-length aromatic spacer arm (11.6 angstroms).

Features of Sulfo-SMPB:

• Reactive groups: sulfo-NHS ester and maleimide
• Reactive towards: amino and sulfhydryl groups
• Extended chain length limits steric hindrance
• Non-cleavable
• Water-soluble (compare to SMPB)
• Membrane impermeable, allowing for cell surface labeling

Abstract
pICln inhibits snRNP biogenesis by binding core spliceosomal proteins.
Authors:Pu WT, Krapivinsky GB, Krapivinsky L, Clapham DE
Journal:Mol Cell Biol
PubMed ID:10330151
'The U1, U2, U4, U5, and U6 small nuclear ribonucleoproteins (snRNPs) form essential components of spliceosomes, the machinery that removes introns from pre-mRNAs in eukaryotic cells. A critical initial step in the complex process of snRNP biogenesis is the assembly of a group of common core proteins (Sm proteins) on ... More
Substrate-induced conformational change in bacterial complex I.
Authors:Mamedova AA, Holt PJ, Carroll J, Sazanov LA
Journal:J Biol Chem
PubMed ID:15037611
'The mechanism coupling electron transfer and proton pumping in respiratory complex I (NADH-ubiquinone oxidoreductase) has not been established, but it has been suggested that it involves conformational changes. Here, the influence of substrates on the conformation of purified complex I from Escherichia coli was studied by cross-linking and electron microscopy. ... More
Decorin evokes protracted internalization and degradation of the epidermal growth factor receptor via caveolar endocytosis.
Authors:Zhu JX, Goldoni S, Bix G, Owens RT, McQuillan DJ, Reed CC, Iozzo RV
Journal:J Biol Chem
PubMed ID:15994311
Decorin inhibits the epidermal growth factor receptor (EGFR) by down-regulating its tyrosine kinase activity, thereby blocking the growth of a variety of transformed cells and tumor xenografts. In this study we provide evidence that decorin directly binds to the EGFR causing its dimerization, internalization, and ultimately its degradation. Using various ... More
Combination of DNA-directed immobilization and immuno-PCR: very sensitive antigen detection by means of self-assembled DNA-protein conjugates.
Authors:Niemeyer CM, Wacker R, Adler M
Journal:Nucleic Acids Res
PubMed ID:12907742
An assay for very sensitive antigen detection is described which takes advantage of the self- assembly capabilities of semi-synthetic conjugates of DNA and proteins. The general scheme of this assay is similar to a two-sided (sandwich) enzyme-linked immunoassay (ELISA); however, covalent single-stranded DNA-streptavidin (STV) conjugates, capable of hybridizing to complementary ... More
Biologically active decorin is a monomer in solution.
Authors:Goldoni S, Owens RT, McQuillan DJ, Shriver Z, Sasisekharan R, Birk DE, Campbell S, Iozzo RV
Journal:J Biol Chem
PubMed ID:14660661
It has been reported that decorin and its protein core can have molecular masses nearly double the size of those previously published, suggesting a dimeric structure. In this study we tested whether biologically active decorin and its glycoprotein core would form dimers in solution. We used homo- and hetero-bifunctional chemical ... More
