RbcL II | Rubisco form II positive control/quantitation standard

RbcL II | Rubisco form II positive control/quantitation standard

APA-PSQ-002

Rubisco (Ribulose-1,5-bisphosphate carboxylase/oxygenase) catalyzes the rate-limiting step of CO2 fixation in photosynthetic organisms. Form II Rubisco is present in many photosynthetic bacteria and archaea and in some photosynthetic dinoflagellates. Source of Rubisco standard: Overexpressed RbcL form II protein

Lyophilized in glycerol.

For reconstitution add 90 μl of sterile water, Please notice that this product contains 10% glycerol and might appear as liquid but is provided lyophilized

52.7 kDa

Western blot (WB)

Standard curve: 3 loads are recommended (0.5, 2 and 4μl).For most applications a sample load of 0.2 μg of chlorophyll/well will give a RbcL signal in this range. Positive control: a 2 μl load per well is optimal for most chemiluminescent detection systems. Higher standard concentration needs to be used to allow detection by Coomasie stains. Such gels with higher standard concentration can not be used for quantitation using chemiluminescence. 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.

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.
