Background
A global transcription regulator. Complexes with cyclic AMP (cAMP) which allosterically activates DNA binding (to consensus sequence 5'-AAATGTGATCTAGATCACATTT-3') to directly regulate the transcription of about 300 genes in about 200 operons and indirectly regulate the expression of about half the genome. There are 3 classes of CRP promoters; class I promoters have a single CRP-binding site upstream of the RNA polymerase (RNAP)-binding site, whereas in class II promoters the single CRP- and RNAP-binding site overlap, CRP making multiple contacts with RNAP. Class III promoters require multiple activator molecules, including at least one CRP dimer. It can act as an activator, repressor, coactivator or corepressor. Induces a severe bend in DNA (about 87 degrees), bringing upstream promoter elements into contact with RNAP. Acts as a negative regulator of its own synthesis as well as for adenylate cyclase (cyaA), which generates cAMP. High levels of active CRP are detrimental to growth.Plays a major role in carbon catabolite repression (CCR). CCR involves cAMP, adenylate cyclase (cyaA), CRP and the EIIA-Glc component of the PTS (crr). In the presence of glucose EIIA-Glc is dephosphorylated, and does not activate adenylate cyclase, leading to reduced cAMP and thus decreased CRP activity. Also plays a role in many other processes

Shipping and storage
crp Antibody is shipped on ice packs and upon receipt should be stored at -20 or -80 degrees Celsius. We recommend that you prepare the working aliquots in advance so that freez-thaw cycles are avoided. Do not expose the antibodies to drirect bright light, especially the labeled ones as most conjugates are light sensitive.
-
Description
This antibody needs to be stored at + 4°C in a fridge short term in a concentrated dilution. Freeze thaw will destroy a percentage in every cycle and should be avoided.
-
Properties
If you buy Antibodies supplied by Cusabio they should be stored frozen at - 24°C for long term storage and for short term at + 5°C. Biotin conjugates can be detected by horseradish peroxidase, alkaline phosphatase substrates or anti biotin conjugated antibodies. Avidin and Streptavidin bind to the small biotin and are couple to HRP or AP for ELISA. To break the streptavidin Biotin bond we suggest to use a 6 molar guanidine HCl solution with acidity of pH 1.6.

Gene
C reactive proteins are detected by anti-CRP antibodies supplied by GENTAUR.

About
Rabbits are used for polyclonal antibody production by Cusabio. Rabbit antibodies are very stable and can be stored for several days at room temperature. Cusabio adds sodium azide and glycerol to enhance the stability of the rabbit polyclonal antibodies. Anti-human, anti mouse antibodies to highly immunogenic selected peptide sequences are" monoclonal like" since the epitope to which they are directed is less than 35 amino acids long.
