生物活性

Nisin is a bacteriocin produced by a group of Gram-positive bacteria that belongs to Lactococcus and Streptococcus species. Nisin has antibacterial and anti-inflammatory activity[1][2][3].

体外研究
(In Vitro)

Nisin (100-800 μg/mL, 36 h) 可抑制 HNSCC 细胞的气球形成[1]
Nisin (500-7000 IU/mL, 24 h) 可诱导自由生活阿米巴棘阿米巴细胞周期阻滞[2]

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

Cell Viability Assay[2]

Cell Line: A. castellanii trophozoites
Concentration: 500, 1000, 2000, 3000, 4000, 6000, 7000 IU/mL
Incubation Time: 24, 72 h
Result: Inhibited amebic growth in a concentration-dependent manner at 24 h.

Cell Cycle Analysis[2]

Cell Line: A. castellanii trophozoites
Concentration: 7000 IU/mL
Incubation Time: 24 h
Result: Increased S phase to 13.3% and the percentage of G1 to 11.1%.
体内研究
(In Vivo)

Nisin (25 mg/kg, 腹腔注射, 连续 7 天) 通过调节促炎性和抗炎性细胞因子的浓度来减少大鼠的子宫炎症[3]

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

Animal Model: Rat uterine endometritis model[3]
Dosage: 25 mg/kg
Administration: i.p. for 7 days
Result: Decreased the endometritis-induced increase in uterine weight, restored endometrial architecture.
Improved levels of B7-2, IFN-γ, IL-2 and IL-8.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
