Use of immunoglobulin coupled to agarose beads for examining

Preparations of purified immunoglobulins, light chains, and unrelated proteins (used as controls) were covalently linked to agarose beads and used to study the specificity of fluorescein isothiocyanate conjugates. The data demonstrate how these beads can be used to detect immunological and non-immunological reactivity in conjugates.

A simple elution strategy for biotinylated proteins bound to

In this protocol, a mutant biotin ligase promiscuously labels proximal binding partners with biotin, and resulting biotinylated proteins are purified using streptavidin conjugated beads. This approach does not require preservation of protein complexes in vitro, making it an ideal approach to identify transient or weak protein complexes.

Dissolvable Polyacrylamide Beads for High‐Throughput Droplet

The polyacrylamide bead can be rapidly dissolved in DTT by a thiol–disulfide exchange reaction. 14 DTT is a common redox reagent that is used to break down protein disulfide bonds and stabilize enzymes, and its addition to dissolve the beads does not influence reverse transcription or PCR. Acrydite-modified DNA primers can be directly

Reversible Functionalization of Clickable Polyacrylamide Gels

BP groups allow gel functionalization with unmodified proteins using photoactivation. Acrylate groups enable copolymer grafting onto the gels. To release the functionalized unit, pAPA gels are treated with disulfide reducing agents, triggering ≈50% release of immobilized protein and grafted copolymers.

polyacrylamide - wikipedia

Polyacrylamide - Wikipedia

Polyacrylamide (abbreviated as PAM) is a polymer with the formula (-CH 2 CHCONH 2 -). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for water treatment and the paper and mineral industries.

Sequencing-Based Protein Analysis of Single Extracellular

One of the challenges with using Bead-DNA BC is the often inefficient reaction within droplets as the DNA is immobilized on beads. We therefore used a technique to dissolve polyacrylamide cross-linked beads by breaking disulfide bridges with dithiothreitol (DTT).24 Once cleaved, these beads rapidly release barcode primers (<3 min at 1 mM

PAK-PBD beads (binds active Rac/Cdc42 proteins

PAK-PBD protein specifically recognizes and binds the active, GTP-bound, forms of the Rac and Cdc42 proteins. It has a much lower affinity for the inactive, GDP-bound, forms of Rac and Cdc42. When coupled to a colored glutathione sepharose matrix, the PAK-PBD protein beads become a convienent tool for assaying the activity of the Rac and Cdc42
