Depositor Notes: Fusion: 1986. Immunohistology: On whole mount Drosophila embryos, it decorates the extracellular matrix surrounding the pericardial cells and the cardial cells of the heart tube, from 10h embryogenesis onwards; it is synthesized and secreted by the pericardial cells; it also labels the ring gland and the oenocytes; no maternal expression; it is still present around the adult heart tube. Immunoblotting with EC11: three bands (200, 190, 165 kDa) differentially expressed during embryogenesis, the 165 kDa species being the only one to persist in the adult heart tube. Functional effects: In the absence of Pericardin, the heart epithelium appears disorganized during its migration in concert with the dorsal ectoderm. The alignment of the cardial and pericardial cells is interrupted by holes and both types of cells are found accumulated in clusters along the rows of cardioblasts. The protein is probably involved in the morphogenesis and in the maintenance of the heart epithelium during dorsal ectoderm closure. Immunohistochemistry: Pericardial cells, extracellular matrix surrounding the heart tube, ring gland, oenocytes.
Host Species: mouse
Hybridoma Cells Available (Non-Profit): Yes
Confirmed Species Reactivity: Drosophila
Additional Information: Pericardin is a type IV collagen-like ECM protein contributing to the ECM layer that surrounds the myocardial–pericardial network. EC1 1 was isolated by chance in a screen for monoclonal antibodies recognizing the muscle myosin heavy chain [PMID 3117889]. There are three Uniprot entries for this protein, two (Q7YU48 and Q9U617) are supported by experimental evidence at transcript level; the third, Q9VTR6, is a predicted protein; all three proteins are quite different; Q9U617 was selected as Uniprot ID because it encodes the NFQSTYYTK peptide identified in [PMID 12070098] by immunoprecipitation and sequencing. In [PMID 12070098], EC11 was used for immunogold on EM.

Storage and Handling Recommendations
Although many cell products are maintained at 4°C for years without loss of activity, shelf-life at 4°C is highly variable. For immediate use, short term storage at 4°C up to two weeks is recommended. For long term storage, divide the solution into volumes of no less than 20 ul for freezing at -20°C or -80°C. The small volume aliquot should provide sufficient reagent for short term use. Freeze-thaw cycles should be avoided. For concentrate or bioreactor products, an equal volume of glycerol, a cryoprotectant, may be added prior to freezing.
Usage Recommendations
The optimal Ig concentration for an application varies by species and antibody affinity. For each product, the antibody titer must be optimized for every application by the end user laboratory. A good starting concentration for immunohistochemistry (IHC), immunofluorescence (IF), and immunocytochemistry (ICC) when using mouse Ig is 2-5 ug/ml. For western blots, the recommended concentration range of mouse Ig 0.2-0.5 ug/ml. In general, rabbit antibodies demonstrate greater affinity and are used at a magnitude lower Ig concentration for initial testing. The recommended concentrations for rabbit Ig are 0.2-0.5 ug/ml (IF, IHC and ICC) and 20-50 ng/ml (WB).
