Description: For sample dialysis, low molecular weight contaminant removal, buffer exchange, desalting, equilibrium dialysis, and concentration. This type of membrane is compatible with a number of common chemicals and buffers. The colour-coded transparent frames of the Slide-A-Lyzer® cassette allow instant recognition of the MWCO of the membrane and make viewing the needle easier during sample injection.
Catalog Number: (PI22309)
Supplier: Invitrogen
Description: Thermo Scientific Pierce GMBS is an amine-to-sulfhydryl crosslinker that contains NHS-ester and maleimide reactive groups at opposite ends of a short spacer arm (7.3 angstroms).

Supplier: Invitrogen
Description: The Thermo Scientific Active GTPase Pull-Down and Detection Kits allows the monitoring of changes in GTPase activity levels by enriching and detecting the active (GTP-bound) state of a particular GTPase.

Catalog Number: (PI89818)
Supplier: Invitrogen
Description: Kit has been optimized to incorporate 1-3 biotinylated ribonucleotides (biotin-N4-CTP) onto the 3' end of DNA strands where the label will be less likely to interfere with hybridization or sequence-specific binding of proteins.

Catalog Number: (PI23238)
Supplier: Invitrogen
Description: The Bradford protein assay is the preferred colorimetric assay for quantifying total protein concentration

Supplier: Invitrogen
Description: Carboxyl groups, in the form of carboxy termini, aspartate residues or glutamate residues, can be targeted for biotin labeling using amine-derivatized biotin molecules. This reaction is mediated by a class of crosslinkers known as carbodiimides and results in the formation of an amide bond. The reaction with EDC, the most common carbodiimide crosslinker, is generally performed in an MES buffer at pH 4.5 - 5 and requires just minutes to complete.
Supplier: Invitrogen
Description: A value-priced, entry-level peroxidase substrate for enhanced chemiluminescence (ECL) that directly replaces costlier products without the need to re-optimize conditions.
Supplier: Invitrogen
