• Target description: Chromogranin-A (UniProt: P10645; also known as CgA, Pituitary secretory protein I, SP-I) is encoded by the CHGA gene (Gene ID: 1113) in human. Chromogranin-A is a secreted protein that is synthesized with a signal peptide aa 1-18), which is subsequently cleaved off to produce the mature form that is further cleaved into 18 different chains with various biological activities. Notably amongst these are Pancreastatin (aa 272-319) that inhibits glucose induced insulin release from the pancreas, Catestain (aa 370-390) that blocks catecholamine release from chromaffin cells and noradrenergic neurons, and Serpinin (aa 429-454) that regulates granule biogenesis in endocrine cells by up-regulating the transcription of protease nexin 1. It may be secreted in the blood as a full-length protein or in fragments after cleavage. Due to its primary expression throughout the neuroendocrine system, it has been widely accepted biomarker for the assessment of neuro-endocrine tumors. It has also been correlated with a several non-malignant systemic disorders, such as hypertension, cardiac, and hepatic failure. This ZooMAb® recombinant monoclonal antibody, generated by our proprietary technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.(Ref.: Gkolfinopoulos, S., et al. (2017). World J. Methodol. 7(1); 9-15).
• Physical form: Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 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.
• Reconstitution: 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.
• Storage and Stability: 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.
