MLC-2A antibody - 311 011AT1

Myosin light chain 2A or MLC-2A is specific for the atrium of the mammalian heart
Mouse monoclonal purified IgG
Cat. No.: 311 011AT1
Amount: 100 µg
Price: $470.00
Cat. No. 311 011AT1 100 µg purified IgG, lyophilized, fluorescence-labeled with ATTO® 647N.

For many of the fluorescence labeled antibodies conjugated to ATTO® dyes from ATTO-TEC the established fluorescence detection systems can be used.
ATTO® 488: λex 500 nm / λem 520 nm
ATTO® 550: λex 554 nm / λem 576 nm
ATTO® 647N: λex 646 nm / λem 664 nm

ATTO®488, ATTO®647N and ATTO®594 dyes are suitable for Stimulated Emission Depletion (STED) microscopy which allows higher resolution imaging compared to confocal laser scanning microscopy.
ATTO®488 and ATTO®594 are also recommended for PALM and dSTORM high resolution microscopy.

This product or portions thereof is manufactured under license from ATTO-TEC GmbH.

Albumin and azide were added for stabilization. For reconstitution add 100 µl H2O to get a 1mg/ml solution in PBS. Either add 1:1 (v/v) glycerol, then aliquot and store at -20°C until use, or store aliquots at -80°C without additives.
Reconstitute immediately upon receipt! Avoid bright light when working with the antibody to minimize photo bleeching of the fluorescent dye.

Background

During cardiogenesis two major isoforms of myosin light chain 2 are co-expressed in a tightly regulated manner. MLC-2A is only present in the atrium while MLC-2V is exclusively expressed in the ventricle. Knock out studies revealed that the 2A isoform cannot substitute for the 2V variant in the ventricular chamber.
Recently it has been demonstrated that embryonic and adult stem cells can be differentiated into cardiomyocytes which may generate suitable replacements for damaged heart tissue in the future.
This monoclonal antibody is a useful tool to distinguish between ventricle and atrium specific cardiomyocytes.
