Recombinant Anthrax Edema Factor protein

Cat.No.: EF-133
Product Overview: Recombinant Anthrax Edema Factor(EF-A) with an alanine residue at the N-terminal was expressed in B. anthracis.
Description: Edema factor (EF) is a calmodulin-dependent adenylate cyclase which can create excess amounts of adenylate cyclase within susceptible cells.
Source: B. anthracis
Species: B. anthracis
Form: When reconstituted with 0.1 ml of water, the concentration of buffer is 5 mM HEPES, 50 mM NaCl, pH 7.5.
Bio-activity: The enzymatic activity of edema factor is assessed in a cell free system by measuring cAMP formation from ATP. The activity of this EF lot is 830 uM cAMP/min/mg EF.
Molecular Mass: 90 kDa
Endotoxin: The endotoxin content, determined using a kinetic chromagenic LAL assay, is 40 EU/mg.
Purity: >95%
Applications: Tissue Culture Application: For tissue culture applications, medium containing glutamine must be fresh. Ammonium ion is released when glutamine breaks down, and may prevent acidification of the endosome thereby inhibiting translocation of LF or EF into the cytosol. A stable form of glutamine may be used.
Storage: This product is packaged aseptically, lyophilized and sealed under vacuum. Store at 2-8 centigrade prior to reconstitution.
Reconstitution: Anthrax toxin proteins, when reconstituted in water, stored at 2-8 centigrade and used successfully within a few hours. However, over longer periods of time, there may be a decline in the enzymatic activity of EF.
Warning: Good laboratory technique should be employed in the safe handling of this product. This requlres observing the following practices:
1. Wear appropriate laboratory attire including a lab coat, gloves and safety glasses.
2. Do not mouth pipette, inhale, ingest or allow to come into contact with open wounds. Wash thoroughly any area of the body which comes into contact with the product.
