SKU: BTL-AGR-A-00015 |
Brand: Agrisera
Product Description
| Cat Number | AS01 016S |

| Category | Primary Antibody |
| Pack Size | 100 µl |
| Description | The psbA gene has been cloned from many species of plants, green algae, and cyanobacteria. The psbA gene is located in the chloroplast genome and encodes for the D1 protein, a core component of Photosystem II. PsbA/D1 is rapidly cycled under illumination in all oxygenic photobionts. Tracking PsbA pools using the Global PsbA antibody can show the functional content of Photosystem II in a wide range of samples.This is a recombinant protein standard, source: Synechocystis PCC 6803. |
| Applications | Western blot (WB) |
| Form | Lyophilized in glycerol. |
| Molecular Weight | The standard has an actual MW of 41.5 kDa, The presence of a His6 tag causes it to run ~1.7 kDa higher on the gel than the native protein, Note that in most systems, PsbA migrates with an apparent MW of between 30 and 35 kDa. |
| Dilution Range | Standard curve: 3 loads are recommended (0.5, 2 and 4 μl).For most applications a sample load of 0.2 μg of chlorophyll will give a PsbA signal in this range.Positive control: a 2 μl load per well is optimal for most chemiluminescent detection systems.Non-disulphie dependent dimers and complexes can be also detected using standard western blot methods with more sensitive detection reagents as ECL Advance or West Pico when loading per well more standard than recommended. They have not been included in the standard calibration.This standard is stabilized and ready and does not require heating before loading on the gel. Please note that this product contains 10% glycerol and might appear as liquid but is provided lyophilized. Allow the product several minutes to solubilize after adding water. Mix thoroughly but gently Take extra care to mix thoroughly before each use, as the proteins tend to settle with the more dense layer after freezing. |
| Reconstitution | For reconstitution, check the label on the tube. Please notice that this product contains 10% glycerol and might appear as liquid but is provided lyophilized |
| Storage | Store lyophilized/reconstituted at -20°C; once reconstituted make aliquots to avoid repeated freeze-thaw cycles. Please remember to spin the tubes briefly prior to opening them to avoid any losses that might occur from material adhering to the cap or sides of the tube. |
