Other description:

Each vial contains 100µl 1mg/ml purified monoclonal antibody in phosphate buffered saline (PBS) containing 0.09% sodium azide.

Properties:

If you buy Antibodies supplied by nordc they should be stored frozen at - 24°C for long term storage and for short term at + 5°C.

Antibody come from:

5E3 is a mouse monoclonal IgG1 antibody derived by fusion of SP2/0 mouse myeloma cells with splenocytes from a BALB/c mouse immunized with Daudi cells, a human Burkitt’s lymphoma cell line.

Antibody's suited for:

The 5E3 antibody is suitable for the detection of human CD23 antigen by flow cytometry. Human tonsil is suitable as a positive control. Optimal antibody dilutions for the different applications should be determined by titration.

Warnings:

This product is intended FOR RESEARCH USE ONLY, and FOR TESTS IN VITRO, not for use in diagnostic or therapeutic procedures involving humans or animals. This datasheet is as accurate as reasonably achievable, but Nordic-MUbio accepts no liability for any inaccuracies or omissions in this information.

Test:

A high affinity purification column was use to purify Mouse anti CD23 antibody immunoglobulin epsilon Fc receptor by nordc by chromatographic size exclusion.Mouse or mice from the Mus musculus species are used for production of mouse monoclonal antibodies or mabs and as research model for humans in your lab. Mouse are mature after 40 days for females and 55 days for males. The female mice are pregnant only 20 days and can give birth to 10 litters of 6-8 mice a year. Transgenic, knock-out, congenic and inbread strains are known for C57BL/6, A/J, BALB/c, SCID while the CD-1 is outbred as strain.

Description:

This antibody needs to be stored at + 4°C in a fridge short term in a concentrated dilution. Freeze thaw will destroy a percentage in every cycle and should be avoided.The receptors are ligand binding factors of type 1, 2 or 3 and protein-molecules that receive chemical-signals from outside a cell. When such chemical-signals couple or bind to a receptor, they cause some form of cellular/tissue-response, e.g. a change in the electrical-activity of a cell. In this sense, am olfactory receptor is a protein-molecule that recognizes and responds to endogenous-chemical signals, chemokinesor cytokines e.g. an acetylcholine-receptor recognizes and responds to its endogenous-ligand, acetylcholine. However, sometimes in pharmacology, the term is also used to include other proteins that are drug-targets, such as enzymes, transporters and ion-channels.

Long description:

The low affinity immunoglobulin E (IgE) Fc receptor, also known as CD23, is a 45kD type II transmembrane glycoprotein. CD23 contains a C-type lectin domain in the extracellular C-terminal region and belongs to group II of the type II lectins. CD23 is a receptor for IgE but can also bind to other ligands such as CD21, CD11b and CD11c. CD23 primarily functions as a B-cell growth and activation factor. It also regulates the synthesis of IgE through binding of IgE and CD21. Two isoforms of CD23 have been described, CD23a and CD23b, which are expressed on different cell types. CD23a expression is restricted to resting B-cells, whereas CD23b is weakly expressed on activated B-cells and other haematopoietic cells. CD23 is also expressed on B-cell chronic lymphocytic leukemia (CLL) cells and is useful as a marker to differentiate CLL from mantle cell lymphoma by flow cytometry. A soluble form of CD23 (sCD23) also exists which is produced by proteolytic cleavage of the membrane bound form. Studies suggest that levels of serum sCD23, in cases of B-CLL, correlate with tumour activity and are an important indicator for early treatment.
