Supplier: AAT BIOQUEST
Description: Many biological compounds present in cells, serum or other biological fluids are naturally fluorescent, and thus the use of conventional, prompt fluorophores leads to serious limitations in assay sensitivity due to the high background caused by the autofluorescence of the biological molecules to be assayed.

Catalog Number: (AATB2349)
Supplier: AAT BIOQUEST
Description: Tide Fluor™ 2WS (TF2WS) family has the spectral properties similar to those of fluorescein, DyLight 488 and Alexa Fluor 488.
UOM: 1 * 5 mg


Catalog Number: (1615138.)
Supplier: USP
Description: USP Reference Standards are specified for use in conducting official USP–NF tests and assays. USP also provides Reference Standards specified in the Food Chemicals Codex as well as authentic substances—high-quality chemical samples—as a service to analytical, clinical, pharmaceutical and research laboratories. To confirm accuracy and reproducibility, USP Reference Standards are rigorously tested and evaluated by multiple independent laboratories including USP, commercial, regulatory, and academic labs. USP also provide publicly available, official documentary standards for pharmaceutical ingredients in the USP–NF that link directly with our primary reference standards.
UOM: 1 * 500 mg

Catalog Number: (PIER21651)
Supplier: Thermo Fisher Scientific
Description: Thermo Scientific Pierce LC-SPDP is a long-chain crosslinker for amine-to-sulfhydryl conjugation via NHS-ester and pyridyldithiol reactive groups that form cleavable (reducible) disulfide bonds with cysteine sulfhydryls.
UOM: 1 * 50 mg


Catalog Number: (PIER22311)
Supplier: Thermo Fisher Scientific
Description: Thermo Scientific Pierce MBS is an amine-to-sulfhydryl crosslinker that contains NHS-ester and maleimide reactive groups at opposite ends of a short aromatic spacer arm (7.3 angstroms).
UOM: 1 * 50 mg


Supplier: AAT BIOQUEST
Description: SMCC is a non-cleavable and membrane permeable crosslinker with a spacer arm of 8.3 Å. It contains an amine-reactive succinimidyl ester (SE) and a sulfhydryl-reactive maleimide group. NHS esters react with primary amines at pH 7 to 9 to form stable amide bonds. Maleimides react with sulfhydryl groups at pH 6.5 to 7.5 to form stable thioether bonds. The SE group of SMCC is reacted with lysine residues on the carrier protein, converting them to reactive maleimides. SMCC is a reagent that is widely used for generating stable maleimide-activated carrier proteins that can spontaneously react with sulfhydryls. Alternatively these relatively stable maleimide-activated intermediates may be lyophilized and stored for later conjugation to a hapten.

UOM: 1 * 1 mg


Supplier: Thermo Fisher Scientific
Description: Thermo Scientific Pierce DSP (Lomant's Reagent) is a water-insoluble, homo-bifunctional N-hydroxysuccimide ester (NHS ester) crosslinker that is thiol-cleavable, primary amine-reactive, and useful for many applications. DSP contains an amine-reactive NHS ester at each end of an 8-carbon spacer arm. NHS esters react with primary amines at pH 7–9 to form stable amide bonds and releasing N-hydroxy-succinimide. Proteins, including antibodies, generally have several primary amines in the side chain of lysine (K) residues and the N-terminus of each polypeptide that are available as targets for NHS ester crosslinking reagents. DSP is non-sulfonated and insoluble in water, so it must first be dissolved in an organic solvent and then added to the aqueous reaction mixture. Because DSP does not possess a charged group, it is lipophilic and membrane-permeable and so useful for intracellular and intramembrane conjugation. A sulfonated analog of DSP (DTTSP) is water soluble. DSS, the non-cleavable analog of the DSP crosslinker is also available for applications that require a stable spacer arm that cannot be cleaved in the presence of reducing agents.

Supplier: AAT BIOQUEST
Description: ReadiLeave™ Reversible (RLR) Biotin is a newly developed biotin derivative that has significantly reduced affinity to avidin (including streptavidin) to make the binding of RLR biotin and streptavidin readily reversible when needed.
