Myosin light chain 2A or MLC-2A is specific for the atrium of the mammalian heart
Rabbit monoclonal recombinant IgG
Cat. No.: 311 018
Amount: 50 µg
Price: $415.00
Cat. No. 311 018 50 µg purified recombinant IgG, lyophilized. Albumin and azide were added for stabilization. For reconstitution add 50 µl H2O to get a 1mg/ml solution in PBS. Then aliquot and store at -20°C to -80°C until use.
Antibodies should be stored at +4°C when still lyophilized. Do not freeze!
Applications
 
WB: 1 : 1000 (AP staining) gallery  
IP: not tested yet
ICC: yes (see remarks)
IHC: 1 : 500 gallery

Western blot (WB); separation of proteins by PAGE and subsequent transfer to a membrane. Detection of target molecules is carried out with antibodies. Some antibodies require special sample preparation steps. For details, please refer to the “Remarks” section.

Immunoprecipitation (IP); Immunoisolation or pulldown of a target molecule using an antibody. For details and product specific hints, please refer to the ”Remarks” section.

Immunocytochemistry (ICC) on 4% PFA fixed cells. Immunoreactivity is usually revealed by fluorescence. Some antibodies require special fixation methods. For details, please refer to the “Remarks” section.

Immunohistochemistry (IHC) on 4% PFA perfusion fixed tissue with 24h PFA post fixation. Immunoreactivity is usually revealed by fluorescence or a chromogenic substrate. Some antibodies require special fixation methods or antigen retrieval steps. For details, please refer to the ”Remarks” section.

Immunohistochemistry (IHC-P) of formalin fixed, paraffin embedded (FFPE) tissue (some antibodies require special antigen retrieval steps, please refer to the ”Remarks” section). Immunoreactivity is usually revealed by fluorescence or a chromogenic substrate.

Clone Rb56F5
Subtype IgG1 (κ light chain)
Immunogen Recombinant protein corresponding to AA 1 to 175 from human MLC-2A (UniProt Id: Q01449)
Reactivity Reacts with: human (Q01449), rat, mouse (Q9QVP4).
No signal: chicken.
Other species not tested yet.
Specificity Specific for MLC-2A, no cross-reactivity to MLC-2V
Matching control protein/peptide 311-0P
Remarks

This antibody is a chimeric antibody based on the well known monoclonal mouse antibody clone 56F5. The constant regions of the heavy and light chains have been replaced by rabbit specific sequences. Therefore, the antibody can be used with standard anti-rabbit secondary reagents. The antibody has been expressed in mammalian cells.
ICC: Methanol fixation gives stronger signals.

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.
