Immunoassay

An immunoassay is a biochemical test that measures the presence or concentration of a macromolecule or a small molecule in a solution through the use of an antibody (usually) or an antigen (sometimes). The molecule detected by the immunoassay is often referred to as an analyte and is in many cases a protein, although it may be other kinds of

Interaction between Amorphous Zirconia Nanoparticles

The amorphous ZrO 2 nanoparticles modified electrode showed enhanced oxidation peak currents as compared to bare CPE, using cyclic voltammetry and differential pulse voltammetry. The electrode also showed an electrochemical oxidative effect towards the determination of GA within a concentration range of 1 10 − 6 to 1 10 − 3 mol L − 1 .

Capture of dengue viruses using antibody

A graphite electrode, molded using graphibond-551R with Fe 2 O 3 powder, was used as the anode. On the opposite side, a graphite rod (50 mm•10 mm; 99.9%) was used as the cathode. The resulting graphite-encapsulated iron compound nanoparticles were then exposed to plasma, which was produced using an RF power supply ( 18, 19 ) in an atmosphere containing ammonia at 13.56 MHz and 80 W

Simple Fabrication of a Highly Sensitive Glucose Biosensor

2007/11/15A novel and highly sensitive electroanalytical sensing nanocomposite material is reported for the development of a glucose biosensor. Exfoliated graphite nanoplatelets (xGnP) were tested to enhance the sensing capability. The xGnP has a diameter of 1 m and a thickness of 10 nm, on average. The glucose biosensing interface was prepared by casting glucose oxidase and xGnP in a Nafion

TensorFlow

TensorFlow is an end-to-end open source platform for machine learning. It has a comprehensive, flexible ecosystem of tools, libraries and community resources that lets researchers push the state-of-the-art in ML and developers easily build and deploy ML powered applications.

Coombs test

A Coombs test, also known as antiglobulin test (AGT) is either of two blood tests used in immunohematology. They are the direct and indirect Coombs tests. The direct Coombs test detects antibodies that are stuck to the surface of the red blood cells.[1] Since these antibodies sometimes destroy red blood cells, a person can be anemic and this

B.1.1.7: What We Know About the Novel SARS

Accordingly, the frequency of S-gene target negatives has been used as a proxy for the frequency of B.1.1.7 identification in the U.K. In the United States, testing is de-centralized and different healthcare systems could be using PCR tests that do not cover the spike protein region and therefore would not be useful in identifying the new variant.

Using same collection tube, add 50L of Elution Buffer 2 to the spin tip. Centrifuge at 1000 g for 5 minutes. 3. Acidify the elution fraction by adding 100L of 2.5% TFA. Ensure the sample pH is 2.0-2.5 for proper binding and desalting on C18 or graphite resins.

Hot Topic: Carbon, Graphite, and Graphene

2021/3/15Talking about carbon, one automatically thinks of carbon nanotubes and fullerenes. But there is much more to this broad subject area. Advances in graphene research, templating methods, and the emergence of nanodiamonds make this field a rich area of research.

In vivo imaging of embryonic vascular development using

In this study we describe a model system that allows continuous in vivo observation of the vertebrate embryonic vasculature. We find that the zebrafish fli1 promoter is able to drive expression of enhanced green fluorescent protein (EGFP) in all blood vessels

Within this group of improved TCRs, a dual substitution in the 1G4 TCR CDR3alpha chain was identified that enhanced Ag-specific reactivity in gene-modified CD4(+) and CD8(+) T cells. Separate experiments on two distinct TCRs that recognize the MART-1 27-35 (AAGIGILTV) peptide/HLA-A*02 Ag complex characterized single amino acid substitutions in both TCRs that enhanced CD4(+) T cell Ag-specific

Improved Detection of Hydrophilic Phosphopeptides Using Graphite Powder Microcolumns

Proteomics studies using mass spectrometry (MS)1 are fo-cused on small- or large-scale identification of proteins and quantification of levels of protein expression. Because protein function often can be dependent on post-translational modi-fications of the

Using plant tissue culture makes the production of secondary metabolite, genetically modified and disease-free plants possible (Murashige, 1974; Khosroushahi et al., 2006). In spite of the advantages of tissue culture technique, some methodological problems, such as microbial contamination of explants hinder its importance as an advanced technique for biotechnological research (Cassells, 1991).
