Anti-Cre Recombinase Antibody, clone 1J11 ZooMAb^® Rabbit Monoclonal

Recombinase cre (UniProt: P06956; also known as Cre) is encoded by the cre gene (Gene ID: 2777477) in Escherichia phage P1 (Bacteriophage P1). Cre (Causes recombination with Cyclization recombinase), a 38 kDa DNA recombinase of the ′phage′ integrase family, is derived from the P1 bacteriophage. It catalyzes site-specific recombination and is highly specific for a 34-bp DNA sequence motif called loxP (locus of X-over P1) found in P1 DNA. The loxP site is composed of a variable asymmetric 8-bp sequence in between two sets of 13-bp palindromic sequences (ATAACTTCGTATA-NNNTANNN-TATACGAAGTTAT). Two cre recombinase proteins, each bind to one of the two 13-bp palindromic sequences at a loxP site, form a dimer. This dimer then binds to a second dimer on another loxP site to form a tetramer. The two sites joined by the tetramer are parallel in orientation and the double stranded DNA is cut at both loxP sites. The strands are then rejoined with DNA ligase. Because the Cre gene and loxP sites are not native to most species, they are often introduced into target cells or tissues and employed as a means to precisely control the expression of genes both in cultured cells in vitro and in animals in vivo. This ZooMAbZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Clone 1J11 is a ZooMAb^® Rabbit recombinant monoclonal antibody that specifically detects Cre Recombinase. It targets an epitope within 15 amino acids from the N-terminal region.

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS, 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 μL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.

Reconstitute lyophilized antibody pellet with 25μL of ultrapure water or Phosphate Buffered Saline (PBS). Please refer to our reconstitution protocol and the specific application guidance on the suggested starting dilutions and sample type.
