Vector Labs Ab01462-30.135-BS Anti-i-motif DNA [iMab], scFv fragment (3xFLAG + His), scFv, (1 mg) Centrifuge Bundle Savings at Sycamore Life Sciences

Description

Product Class: Purified
Clone ID: iMab
Heavy Chain Modification: scFv
Synonyms: intercalated motif; i-motif; intercalated DNA motif; I motif; DNA i-motif; human telomere i-motif ; hTelo i-motif; imotif; imotiv; imotive; i-motiv; i-motive
Amount: 1 mg
Application Codes Clone: ELISA; BLI; IF; confocal microscopy
Shipping Temperature: Wet Ice
Buffer Composition: PBS only.
Original Format: scFv
Storage Temperature: Store at 4⁰C for up to 3 months. Note, this antibody is provided without added preservatives, it is therefore recommed this antibody be handled under sterile conditions. For longer storage, aliquot and store at -20⁰C.
Specificity Statement: This antibody is specific for the DNA i-motif, a four-stranded DNA structure that forms in cytosine-rich regions and is potentially involved in regulating DNA function.
Application Notes: The original human scFv version of this antibody was validated for its specificity towards various i-motif types through ELISA and bio-layer interferometry (BLI), with a dissociation constant (K_D) of 59 nM. It selectively binds to i-motifs, including those in 1G22, 1A83, c-MYC, RET, and VEGF sequences, located in regions such as telomeres, centromeres, and proto-oncogene promoters. Importantly, this antibody does not interact with structures resembling i-motif DNA, such as DNA G4 quadruplex forms, double-stranded DNA (dsDNA), hairpin DNA, miRNA, or mutant human telomeres lacking i-motifs (Zeraati et al., 2018; PMID: 29686376). Notably, it does not bind to various DNA G4 quadruplex forms, including promoter G4s c-MYC44, BCL245, VEGF, telomeric 2JSM47, 2GKU, or aptamer G4 TBA. Additionally, the antibody has proven effective for immunofluorescence detection of i-motifs in multiple cell lines (MCF7, U2OS, and HeLa), confirming the presence of i-motif structures in human nuclei and their dependence on pH and cell-cycle stage (Zeraati et al., 2018; PMID: 29686376). This antibody selectively binds to both intramolecular and intermolecular i-motif structures. The composition of buffers used during binding and washing steps significantly influences the antibody's selectivity, emphasizing the importance of optimizing DNA concentrations, blocking conditions, and washing protocols. These factors are crucial for confirming the antibody's selectivity for i-motifs and ensuring accurate detection of both intramolecular and intermolecular i-motifs (Ruggiero et al., 2024; DOI: 10.1101/2024.06.22.600195v1).
