Clone 4E7 is a ZooMAb^® rabbit recombinant monoclonal antibody that detects Carbamidomethyl-cysteine (CAM-Cysteine) modified proteins.

A linear peptide corresponding to 26 amino acids from the C-terminal region of human Myeloid associated differentiation marker like 2 ( MYADML2 ) with CAM modification at two Cysteine residues.

Post-translation regulation of cysteine sulfhydryl groups can affect molecular function of proteins. In several secreted proteins, cysteine thiols undergo oxidation to form intramolecular disulfide bonds, which play key roles in protein secondary structure and function. In order to be quantified in a protein cysteine residue requires modification. Thiol group of cysteine can be blocked by a variety of reagents, including iodoacetic acid and iodoacetamide. Iodoacetate treatment can produce S-carboxymethyl derivative of cysteine, but it introduces a new negative charge into protein. However, when such charge difference is undesirable, iodoacetamide is used to derivatize cysteine to produce carboxamidomethyl cysteine, an irreversible covalent product. These modifications in proteins can serve as markers for cysteine-AGE formation and can be used as marker for mitochondrial damage during aging. Antibodies that react with carbamidomethyl-cysteine (CAM-cys) can provide multiple protein bands when subjected to Western blotting of lysates treated with iodoacetamide. This ZooMAbZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

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.

300 μg/mL after reconstitution at 25 μL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

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.
