Cys-CPP44

Name: Cys-CPP44
Brand: MedChemExpress
SKU: HY-P11926
Availability: PreOrder

Cys-CPP44 is a cell-penetrating peptide with a Cys introduced at the N-terminus, which can specifically penetrate hepatocellular carcinoma cells. Modification with Cys-CPP44 promotes the specific penetration of arsenic trioxide-loaded liposomes into hepatocellular carcinoma cells and enhances the cellular uptake of liposomes by these cells. Cys-CPP44 can be used for the research of hepatocellular carcinoma.

Others

Cys-CPP44 forms DSPE-PEG-MAL-CPP44 conjugate whose successful synthesis is verified by MALDI-TOF-MS at m/z = 5042.349[1].
Cys-CPP44 significantly elevates the uptake efficiency of modified liposomes (CPP44-Lp) in HepG2 cells compared with unmodified liposomes^[1].

Anti-cancer

Cys-CPP44-modified ATO liposomes (CPP44-ATO-Lp) significantly reduce the viability of HepG2 cells compared with free ATO and unmodified ATO-Lp; after incubation with 0.05 μM ATO for 24 h, the total apoptosis rate of HepG2 cells reaches 25.48%^[1].

In Vivo

Anti-cancer

Cys-CPP44 combined with anti-GPC3 antibody forms dual-ligand liposomes (0.1 mg/kg; intravenous injection; once every two days for 18 days), which deliver arsenic trioxide to subcutaneous hepatocellular carcinoma tumours in BALB/c nude mice, achieve a tumour inhibition rate of 63.43% and exhibit low systemic toxicity^[1].
Cys-CPP44 paired with anti-GPC3 antibody constructs dual-ligand liposomes (1 mg/kg; intravenous injection; single administration), which display enhanced tumour-targeted accumulation and prolonged retention in orthotopic hepatocellular carcinoma tumours of BALB/c nu/nu mice, with 1.43-fold higher tumour fluorescence intensity at 24 h post-administration relative to unmodified liposomes^[1].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
