AI Article Synopsis

  • Several initiatives are focused on creating binding reagents for analyzing a wide range of proteins in the proteome.
  • Current labeling methods require large amounts of antibodies, need them to be pure, and aren't easily automated, posing limitations for efficient analysis.
  • A new protocol has been developed that allows for the purification and modification of antibodies at very low amounts, utilizing magnetic microspheres for automated parallel labeling with biotin or fluorescent dyes.

Article Abstract

There are currently several initiatives that aim to produce binding reagents for proteome-wide analysis. To enable protein detection, visualization, and target quantification, covalent coupling of reporter molecules to antibodies is essential. However, current labeling protocols recommend considerable amount of antibodies, require antibody purity and are not designed for automation. Given that small amounts of antibodies are often sufficient for downstream analysis, we developed a labeling protocol that combines purification and modification of antibodies at submicrogram quantities. With the support of magnetic microspheres, automated labeling of antibodies in parallel using biotin or fluorescent dyes was achieved.

Objective: Focused ultrasound (FUS)-mediated blood-brain barrier (BBB) opening is safe and potentially beneficial in patients with Alzheimer's disease (AD) for the removal of amyloid-beta (Aβ) plaques. However, the optimal BBB opening intervals and number of treatment sessions for clinical improvement remain undefined. Therefore, the aim of this study was to evaluate the safety and benefits of repeated and more extensive BBB opening alone.

Background: mRNA-1283 is an investigational COVID-19 mRNA vaccine encoding the receptor-binding and N-terminal domains of the SARS-CoV-2 spike protein in contrast to the original mRNA-1273, which encodes the full-length spike protein.

Methods: A phase 2a, dose-ranging, observer-blind, randomized study (NCT05137236) conducted in adults (≥18 years) previously vaccinated with mRNA-1273 evaluated the safety and immunogenicity of a single dose of mRNA-1283 (2.5, 5, and 10 µg) and its bivalent formulation, mRNA-1283.

Over recent years, the LUMinescent AntiBody Sensor (LUMABS) system, utilizing bioluminescence resonance energy transfer (BRET), has emerged as a highly effective method for antibody detection. This system incorporates NanoLuc (Nluc) as the donor and fluorescent protein (FP) as the acceptor. However, the limited Stokes shift of FP poses a challenge, as it leads to significant spectral cross-talk between the excitation and emission spectra.

Cancer diagnostics often faces challenges, such as invasiveness, high costs, and limited sensitivity for early detection, emphasizing the need for improved approaches. We present a surface-enhanced Raman scattering (SERS)-based platform leveraging inverted pyramid SU-8 nanostructured substrates fabricated via nanoimprint lithography. These substrates, characterized by sharp apices and edges, are further functionalized with (3-aminopropyl)triethoxysilane (APTES), enabling the uniform self-assembly of AuNPs to create a highly favorable configuration for enhanced SERS analysis.

SummaryPrevious studies have suggested that chromogranin A (CgA) is a partner molecule of secretogranin III (SgIII). In mouse pituitary corticotroph-derived AtT-20 cells, SgIII plays a role in sorting CgA/hormone aggregates into secretory granules (SGs). Although CgA expression is equivocal, CgB is clearly detectable in the rat pituitary corticotrophs.
