Nab-Paclitaxel  (Synonyms: Nanoparticle albumin-bound Paclitaxel; Nanoparticle albumin-bound ABI-007)

Cat. No.: HY-P99974 Purity: 99.70%
Technical Support

Nab-Paclitaxel (Nanoparticle albumin-bound Paclitaxel) is an albumin-bound nanoparticle formulation of Paclitaxel (HY-B0015). Nab-Paclitaxel is composed of albumin and the active pharmaceutical ingredient Paclitaxel, in which human albumin is used as an excipient to disperse and stabilize particles and carry the main drug. Nab-Paclitaxel is a solvent-free taxane with higher response rates and improved tolerability. Nab-Paclitaxel displays less toxicity and greater antitumor activity. Nab-Paclitaxel is more readily available for tumor cell uptake in three rhabdomyosarcoma, seven neuroblastoma cell lines, and one ostersarcoma cell line Nab-Paclitaxel can be studied in cancer research for example breast cancer and solid tumors. (The product specifications below only indicate the effective content of Paditaxel, the actual albumin quality depends on the batch; the ratio of each ingredient in this product is Paditaxel: albumin -1:7~1:11).

In Vitro

Nab-Paclitaxel (0.1 nM-10 μM, 72 h) is more readily available for tumor cell uptake in three rhabdomyosarcoma, seven neuroblastoma cell lines, and one ostersarcoma cell line[3].
Nab-Paclitaxel (12-120 nM, 48 h) increases apoptotic RH4 cells and most cells detaches from the coveslips with higher concentration (60 or 120 nM)[3].

Cell Cytotoxicity Assay[3]

Cell Line: Three rhabdomyosarcoma cell lines(RH4, RH30, and RD), seven neuroblastoma cell lines (CHLA-20, CHLA-15, CHLA-90, LAN-5, SK-N-BE(2), BE(2)C, and SH-SY5Y) and one osteosarcoma cell line (KHOS)
Concentration: 0.1 nM, 1 nM, 10 nM, 100 nM, 1 μM, 10 μM
Incubation Time: 72 h
Result: Reduced the cell viability of the three rhabdomyosarcoma cell lines with IC50 ranging from 0.56 to 4.68 nM.
Exhibited dose-dependent cytotoxicity in seven neuroblastoma cell lines, where CHLA-20 has the highest IC50 of 36 nM.
In Vivo

Nab-Paclitaxel (30-50 mg/kg, i.v., administer on day 1, 8, 15) significantly inhibits RH4 tumor growth with tumor regression after second dosage on day 8 in mice bearing rhabdomyosarcoma (RH4 and RD) xenografts[3].
Nab-Paclitaxel (2-10 mg/kg, i.v., daily) significantly inhibits tumor growth with 5 and 10 mg/kg in neuroblastoma (SK-N-BE (2) and CHLA-20) xenograft (s.c.) mice[3].
Nab-Paclitaxel (50 mg/kg, i.v., weekly) has the strongest antitumor activity and significantly prolongs animal survival[3].
Nab-Paclitaxel (10 mg/kg, i.v., 5 consecutive days or 50 mg/kg, i.v., weekly) displays lower plasma paclitaxel concentrations but higher intratumor paclitaxel concentrations in both rhabdomyosarcoma and neuroblastoma mice model[3].

Animal Model: Female NOD/SCID (nonobese diabetic/severe combined immunodeficient) mice 4- to 6-week old bearing rhabdomyosarcoma (RH4 and RD) xenografts[3]
Dosage: 30, 50 mg/kg
Administration: Intravenous injection (i.v.), administer on day 1, 8, 15 then 52, 59, 66
Result: Exhibited lower toxicity to mice compared with Paclitaxel.
Increased local relapse-free intervals.
Significantly inhibited tumor growth and led to tumor shrinkage.
Remained sensitivity in mice with relapse RH4 xenografts against Nab-Paclitaxel whilst the xenografts were drug resistant against Paclitaxel.
Led to complete regression after day 29, but a few had relapsed tumor after 37 to 42 days.
Animal Model: Female NOD/SCID (nonobese diabetic/severe combined immunodeficient) mice 4- to 6-week old bearing rhabdomyosarcoma or neuroblastoma xenografts[3]
Dosage: 10 mg/kg for 5 consecutive days or 50 mg/kg weekly
Administration: Intravenous injection (i.v.)
Result: Significantly increased apoptotic cell population in a dose-dependent manner.
Increased phospho-histone H3-positive cells in a dose-dependent manner.
Induced G2-M cell-cycle arrest.

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.
