Protein Analysis Reagents
Invitrogen™ Streptavidin, lyophilized powder
A bacterially derived biotin-binding protein that reportedly exhibits less nonspecific binding than avidin.
Thermo Scientific™ pT7CFE1-CHis Vector for Mammalian Cell-Free Protein Expression
Generate His-, HA-, Myc- or other label-tagged fusion proteins by cell-free in vitro translation (IVT) with these versatile T7 expression vectors.
Thermo Scientific™ L-Photo-Leucine
Diazirine analogs of leucine and methionine to express proteins in cell culture that will crosslink their protein interactors upon UV-light activation in vivo.
Thermo Scientific™ Mass Spectrometry Cleavable Crosslinkers
Improve sensitivity of mass spectrometry detection of crosslinked proteins with MS-cleavable DSSO and DSBU heterotrifunctional crosslinkers.

Thermo Scientific™ SPB (succinimidyl-[4-(psoralen-8-yloxy)]-butyrate)
Crosslink amines to DNA with this crosslinker composed of NHS-ester and psoralen reactive groups; conjugates to DNA via light-activated intercalation next to pyrimidine bases.
Thermo Scientific™ L-Photo-Methionine
Diazirine analogs of leucine and methionine to express proteins in cell culture that will crosslink their protein interactors upon UV-light activation in vivo.
Thermo Scientific™ DTSSP (3,3'-dithiobis(sulfosuccinimidyl propionate))
Crosslink amines to amines with Sulfo-DSP; composed of sulfo-NHS-ester groups and disulfide spacer arm (12.0A) that is cleavable with reducing agents.
Thermo Scientific™ BMPH (N-β-maleimidopropionic acid hydrazide)
Crosslink sulfhydryls to periodate-treated glycoprotein sugars with this short (8.1A) crosslinker containing maleimide and hydrazide groups.
Thermo Scientific™ AMAS (N-α-maleimidoacet-oxysuccinimide ester)
Crosslink amines to sulfhydryls with this very short crosslinker composed of NHS-ester and maleimide groups at ends of an aliphatic, 4-atom (4.4A) spacer arm.
Thermo Scientific™ BS3 (bis(sulfosuccinimidyl)suberate)
Crosslink amines to amines with BS3; composed of sulfo-NHS-ester groups separated by an 11.4A, water-soluble spacer arm that is useful for cell-surface protein crosslinking.
Thermo Scientific™ NHS-Azide
Activated azido compounds to derivatize proteins or amine surfaces for selective conjugation, detection or purification by phosphine-modified probes.
Thermo Scientific™ Pierce™ Premium Grade DSP (dithiobis(succinimidyl propionate))
Optimize applications where product integrity and risk minimization are paramount with our highest quality formulation of this popular amine-reactive, cleavable crosslinker.
