Epothilone B is a microtubule stabilizer (MSA) with a K_i of 0.71μM, and is a MSA with blood-brain barrier permeability. Epothilone B acts by binding to the αβ-tubulin heterodimer subunit which causes decreasing of αβ-tubulin dissociation.

In Vitro

Epothilone B inhibits HCT116 cells with IC₅₀ of 0.8 nM in HCT-116 cell line cytotoxicity assay^[1]. Epothilone B (Patupilone) is a microtubule (MT) targeting agent. As shown by MTT cell proliferation assay, after 72 h of treatment Epothilone B efficiently inhibits cell growth with an IC₅₀ of 6 nM, while concentrations ≤1 nM are not cytotoxic. Epothilone B significantly inhibits transwell cell migration at the non-cytotoxic concentration of 1 nM, and the effect is more evident at 10 nM^[2]. Epothilone B (Patupilone) is a novel, non-taxane-related and nonneurotoxic microtubule-stabilizing agent in human medulloblastoma cell lines. Epothilone B reduces the proliferative activity in the D341 cell line, with an IC₅₀ of 0.53 nM; in the D425Med cell line, with an IC₅₀ of 0.37 nM; and in the DAOY cell line, with an IC₅₀ of 0.19 nM. In the D341Med cell line, the effect of Epothilone B on clonogenic survival is at dose range of Epothilone B similar to the level of proliferative activity and viability (IC₅₀, 0.50-0.75 nM). However, the clonogenicity of D425Med and DAOY cells is already strongly reduced at a 10-fold lower concentration of Epothilone B (IC₅₀, 30 pM). These results overall demonstrate that Epothilone B is highly potent against different medulloblastoma cell lines^[3].

In Vivo

Treatment with Epothilone B (Patupilone) or ionizing radiation alone results in a partial tumor growth suppression over 10 days, whereas combined treatment exerts a strong supra-additive tumor growth control, with complete tumor regression in the follow-up period (P<0.005, for ionizing radiation or Epothilone B alone vs combined treatment)^[3].

Research Protocol for Multiple sequence alignment
Multiple sequence alignment is a computational method for arranging DNA, RNA, or protein sequences so that homologous residues or nucleotides are placed in the same columns, enabling conservation analysis, motif detection, structure prediction, phylogenetic inference, and evolutionary interpretation. MSA accuracy depends on sequence similarity, length variation, insertions and deletions, domain architecture, sequence number, and algorithm choice; therefore, no single aligner is optimal for every dataset. Commonly used MSA tools include MAFFT, MUSCLE, Clustal Omega, and T-Coffee; MAFFT provides multiple strategies for diverse alignment problems, MUSCLE emphasizes speed and accuracy, Clustal Omega scales well to large protein datasets, and T-Coffee uses consistency information to improve alignment reliability. Unresolved issues include alignment uncertainty in divergent sequences, over-alignment of unrelated regions, variable effects of automated trimming, and propagation of alignment er
Transepithelial/transendothelial electrical resistance assay
TEER measures electrical resistance across epithelial or endothelial monolayers cultured on permeable supports, and the readout reflects ionic conductance through the cell barrier, especially the paracellular pathway regulated by junctional integrity. TEER can be measured without destroying the monolayer and is commonly used before or during transport, permeability, barrier-disruption, and barrier-maturation experiments. TEER values are influenced by biological maturation and technical conditions; reported factors include temperature, medium formulation, passage number, electrode geometry, membrane properties, and junctional length during early monolayer maturation. Therefore, TEER should be interpreted with blank-insert subtraction, area normalization, repeated readings, and, when possible, orthogonal barrier readouts such as FITC-dextran flux or tight-junction staining.

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.
