anti-Immunoglobulin G (IgG) secondary antibodies

Each IgG is composed of four peptide chains - two class γ heavy chains of about 50 kDa and two light chains of about 25 kDa - with two antigen binding sites. Hence, IgG antibodies are large molecules of about 150 kDa. Read more

anti-Immunoglobulin A (IgA) secondary antibodies

Immunoglobulin A plays a role in mucosal immunity and is produced in mucosal linings. Hence IgA can be found in mucous secretions, including tears, saliva, colostrum, secretions from the gastrointestinal tract, and others, but it is found only in small amounts in blood. Read more

anti-Immunoglobulin E (IgE) secondary antibodies

IgE is only found in mammals. IgE is the least abundant isotype of all antibodies, but it is capable of triggering the most powerful immune reactions. IgE plays an important role in allergy, and leads to excessive activation of mast cells and basophils by binding to their Fc receptors, resulting in an extreme inflammatory response. Read more

anti-Immunoglobulin D (IgD) Secondary Antibodies

Immunoglobulin D is a monomeric antibody isotype that is expressed in the plasma membranes of immature B-lymphocytes. IgD is also produced in a secreted form that is found in small amounts in blood serum. Read more

anti-Immunoglobulin M (IgM) secondary antibodies

IgM is constructed of five or six units (i.e. mostly as pentamers but also hexamers occur) which are each comprised of two heavy-chains (mu-chains) and two light chains, bound together by disulfide bonds and a so-called J-chain. Read more

anti-Immunoglobulin Y (IgY) secondary antibodies

Immunoglobulin Y (IgY) is found in birds, and it is being isolated for biotechnological applications from egg-yolk of chicken eggs. Studies have suggested that Immunoglobulin Y is functionally similar to IgG, and also shares some similarity with IgE. Read more

Peptide Synthesis - Methods and Reagents

In organic chemistry, peptide synthesis is the production of peptides, in which multiple amino acids are linked via peptide bonds. Read more

Magnetic Beads

Magnetic beads are an ideal tool for immobilizing molecules like proteins (enzymes, antibodies, peptides etc.) or nucleic acids on a solid phase; they can be further used in various applications. Read more

Products for Plant-specific Targets

Modern molecular biology has opened up a whole new range of techniques and possibilities to scientists working in the different fields of the classical plant sciences like plant physiology, breeding or pathology. Read more

Protein Labels

Biological research often requires the use of molecular labels that are covalently attached to a protein of interest to facilitate detection or purification of the labeled protein and/or its binding partners. Read more

Protein Expression Systems

Production of functional proteins is a crucial step for scientist in order to investigate the function and structure requires of proteins of interest. Read more

Model Organisms

When researchers look for an organism to use in their studies, they look for several traits. Among these are size, generation time, accessibility, manipulation, genetics, conservation of mechanisms, and potential economic benefit. Read more

Chromatin immunoprecipitation (ChIP)

Immunoprecipitation of protein-DNA complexes (ChIP) enables the study of epigenetic relations. The technique identifies binding sites of DNA-associated proteins and allows a closer study of transcription factors. Read more

CUT&RUN - Improved Method to Study Protein-DNA Interactions

CUT&RUN-sequencing, also known as Cleavage Under Targets and Release Using Nuclease, is a method used to analyze protein interactions with DNA. CUT&RUN-sequencing combines  antibody-targeted controlled cleavage by micrococcal nuclease with massively parallel DNA sequencing to identify the binding sites of DNA-associated proteins. Read more

SARS-CoV-2 Life Cycle: Stages and Inhibition Targets

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) belongs to the enveloped positive-sense RNA viruses. This virus is characterized by club-like spikes on the surface, and a unique replication strategy. Cell entry of coronaviruses depends on binding of the viral spike (S) proteins to cellular receptors and on S protein priming by host cell proteases. Unravelling which cellular factors are used by SARS-CoV-2 for entry might provide insights into viral transmission and reveal therapeutic targets. Read more
