In Vitro

Melarsoprol (1-100 nM; 24-96 h) causes a dose- and time-dependent inhibition of survival and growth in lymphoid leukemic cells^[2].
Melarsoprol (10-100 nM; 24 h) exhibits morphologic characteristics of apoptosis^[2].
Melarsoprol (1-100 nM; 24 h) inhibits the expression of bcl-2 mRNA and protein^[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Viability Assay^[2]

Cell Line:

An Epstein-Barr virus (EBV)-transformed B-prolymphocytic cell line (JVM-2), an EBV-transformed B-cell chronic lymphocytic leukemia (B-CLL) cell line (I83CLL), and one non-EBV-transformed B-CLL cell line (WSU-CLL)
Concentration:

1 nM, 10 nM, 100 nM
Incubation Time:

24 h, 48 h, 96 h
Result:

Caused a dose- and time-dependent inhibition of survival and growth in all three cell lines.

Apoptosis Analysis^[2]

Cell Line:

WSU-CLL, I83CLL and JVM-2 cells
Concentration:

10 nM, 100 nM
Incubation Time:

24 h
Result:

Showed characteristic apoptotic changes, such as chromatin condensation and fragmentation, membrane blebbing, and formation of apoptotic bodies.

RT-PCR^[2]

Cell Line:

WSU-CLL, I83CLL and JVM-2 cells
Concentration:

10 nM, 100 nM
Incubation Time:

24 h
Result:

Observed prominent concentration-dependent downregulation of bcl-2 mRNA.

Western Blot Analysis^[2]

Cell Line:

WSU-CLL, I83CLL and JVM-2 cells
Concentration:

1 nM, 110 nM, 100 nM
Incubation Time:

24 h
Result:

Decrease of bcl-2 protein expression was observed.

In Vivo

In mice, the organic solution of Melarsoprol (0.039 mmol/kg), injected intravenously as control formulation, is found to concentrate significantly in the bone marrow (C_max = 1.64 mmol/g), though, the brain concentration is quite high (C_max = 0. 093 mmol/g) and the LD₅₀ is 0.12 mmol/kg^[3].

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.
