Onion root meristem cells undergo a concentration-dependent decrease in response to rhodamine B. Mitotic action. Onion mushrooms exhibit a variety of nuclear aberrations caused by rhodamine B. root cells. The frequencies of NBUD and BN were higher in the 100 and 200 ppm rhodamine B groups than they were in the positive control (MMS) group. The levels of MDA (b) and H2O2 (a) in onions increased in a concentration-dependent way when exposed to rhodamine B. root [1].

| Cell Assay |
The cytogenetic toxicity of rhodamine B on root tip cells of Allium cepa was investigated. A. cepa were cultured in water (negative control), 10 ppm methyl methanesulfonate (positive control), and three concentrations of rhodamine B (200, 100, and 50 ppm) for 7 days. Rhodamine B inhibited mitotic activity; increased nuclear anomalies, including micronuclei, nuclear buds, and bridged nuclei; and induced oxidative stress in A. cepa root tissues. Furthermore, a substantial amount of long nucleoplasmic bridges were entangled together, and some nuclei were simultaneously linked to several other nuclei and to nuclear buds with nucleoplasmic bridges in rhodamine B-treated cells. In conclusion, rhodamine B induced cytogenetic effects in A. cepa root tip cells, which suggests that the A. cepa root is an ideal model system for detecting cellular interactions [1].

Absorption, Distribution and Excretion
... WAS METABOLIZED SIMILARLY IN DOGS, RATS & RABBITS, AS EVIDENCED BY CHROMATOGRAPHIC ANALYSIS OF THEIR URINE & FECAL EXTRACTS. CMPD WAS EXTENSIVELY ABSORBED FROM GI TRACT: OF 1% GIVEN IN DIET, ONLY 3-5% WAS RECOVERED UNCHANGED IN URINE & FECES. RHODAMINE B EXHIBITS HIGH PLASMA PROTEIN BINDING. INTENSITY OF DYE COLOR IN PANCREATIC JUICE OF DOGS DECR IN ORDER: BASIC FUCHSINE, ACRIDINE RED, NEW FUCHSINE, RHODAMINE B, PHENOL RED, RHODAMINE 6G. The adsorption equilibrium (as determined by Langmuir's or Freundlich's equations) of microbial suspensions containing Rhodamine B, and melting temperature of Rhodamine B-calf thymus DNA solution were determined. The adsorption constant of dye to cells for Rhodamine B was 6.86 cal/mol (adsorptive affinity in Langmuir's equation) and 2.86 (for the constant K in Freundlich's equation). Melting temperature values for Rhodamine B calf thymus DNA solution increased with dye concentration. Metabolism / Metabolites ... DE-ETHYLATED ENZYMATICALLY; 2 OF 3 OBSERVED METABOLITES WERE IDENTIFIED AS N,N'-DIETHYL-3,6-DIAMINOFLUORAN & 3,6-DIAMINOFLUORAN. |

D&C Red No. 19 can cause cancer according to The Food and Drug Administration (FDA).
C.i. food red 15 appears as green crystals or reddish-violet powder. Used as a dye, especially for paper, as a metal chelating reagent, and in drugs and cosmetics. Rhodamine B is an organic chloride salt having N-[9-(2-carboxyphenyl)-6-(diethylamino)-3H-xanthen-3-ylidene]-N-ethylethanaminium as the counterion. An amphoteric dye commonly used as a fluorochrome. It has a role as a fluorochrome, a fluorescent probe and a histological dye. It is an organic chloride salt and a xanthene dye. It contains a rhodamine B(1+). Rhodamine is a class of xanthene derivatives with fluorescent properties that are used as tracer dyes in a wide variety of industrial and laboratory applications. |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.08 mg/mL (4.34 mM) (saturation unknown) in 10% DMSO + 40% PEG300 +5% Tween-80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 + to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: 5 mg/mL (10.44 mM) in PBS (add these co-solvents sequentially from left to right, and one by one), clear solution; with ultrasonication (<60°C). (Please use freshly prepared in vivo formulations for optimal results.) |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
