ZooMAb^® antibodies represent an entirely new generation of recombinant monoclonal antibodies. Each ZooMAb^® antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb^® antibodies are reliably available and ready to ship when you need them.

Clone 1H6 is a ZooMAb^® rabbit recombinant monoclonal antibody that specifically detects Rap1 GTPase-GDP dissociation stimulator (RAP1GDS1). It targets an epitope within 23 amino acids from the internal region.

KLH-conjugated linear peptide corresponding to 23 amino acids from the internal region of human Rap1 GTPase-GDP dissociation stimulator (RAP1GDS1).

Rap1 GTPase-GDP dissociation stimulator (UniProt: P52306; also known as Exchange factor smgGDS, SMG GDS protein, SMG P21 stimulatory GDP/GTP exchange protein) is encoded by the RAP1GDS1 (also known as SMGGDS) gene (Gene ID: 5910) in human. RAP1GDS1 acts as a guanine nucleotide exchange factor (GEF) for the Rho family of small G proteins that stimulate the dissociation of GDP to enable subsequent binding of GTP. Its nuclear export signal is localized in amino acids 4 to 13 and residues 379-428 are reported to be essential for its catalytic activity. It chaperones the processing and/or trafficking of small GTPases containing a C-terminal polybasic region independently of the GEF activity. It is reported to regulate mitochondrial dynamics by controlling RHOT function to promote mitochondrial fission during high calcium conditions. It can promote the Ca2+ release from the endoplasmic reticulum (ER) via both IP3 and ryanodine sensitive receptors leading to enhanced mitochondrial Ca2+ uptake. Six isoforms of RAP1GDS1 have been described that are produced by alternative splicing. Isoform 1 acts as a GEF for unprenylated Ras homolog family member A (RhoA) and chaperones the entry and passage of small GTPases through the prenylation pathway. Isoform 2 acts as a GEF for prenylated RhoA and chaperones the downstream trafficking and/or processing of small prenylated GTPases. This ZooMAb^® 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 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.

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.
