Abstract: Formulations, methods, and kits comprising at least one Clostridium toxin derivative and at least one chemical depolarizing agent suitable for inducing local, partial or complete muscle paralysis or muscle denervation in a subject are described.

Abstract: Methods for delivery of a biologic agent to the dermis or superficial muscles by topical application of the agent are provided. The methods comprise, in one embodiment, treating or conditioning a skin area to disrupt the stratum corneum in the skin area to define a treated skin area and applying a formulation comprising a biologic agent to the treated skin area.

Abstract: Pharmaceutical compositions that extend the effect and duration of a Clostridial toxin active ingredient are described. The compositions can be liquid or solid compositions, and comprise a non-cross-linked hyaluronic acid or salt thereof as described in the application, a surfactant and an antioxidant. In some embodiments, the compositions comprise a surfactant selected from a poloxamer and a polysorbate; an antioxidant selected from methionine. N-acetyl cysteine, ethylenediaminetetraacetic acid and combinations thereof, and, optionally, a tonicity agent and/or a lyoprotector selected from, for example, trehalose, sucrose.

Abstract: Formulations, methods, and kits comprising at least one Clostridium toxin derivative and at least one chemical depolarizing agent suitable for inducing local, partial or complete muscle paralysis or muscle denervation in a subject are described.

Abstract: An in vivo assay to evaluate topical delivery of a biologic agent from a formulation is provided. The assay comprises treating a skin area of a CD hairless rat with tape stripping to disrupt the stratum corneum in the skin area to define a treated skin area and topically applying a formulation to the treated skin area. The formulation, in one embodiment, comprises the biologic agent and a pharmaceutically acceptable carrier. Delivery of the biologic agent into the skin from the topically applied formulation is evaluated via in vitro or in vivo techniques.

The methods comprise, in one embodiment, treating or conditioning a skin area to disrupt the stratum corneum in the skin area to define a treated skin area and applying a formulation comprising a biologic agent to the treated skin area.

Abstract: The present invention relates to methods and probes for detecting relative levels of multiple nucleic acid sequences of interest. The invention includes a method to detect the relative amounts of at least two target nucleic acid sequences in at least one sample by use of a corresponding set of detectably labelled oligonucleotide probes for each of the at least two target nucleic acid sequences, and detecting the hybridization of each of the corresponding sets of oligonucleotide probes to its respective target nucleic acid sequence. The invention also includes a method to detect the relative amounts of multiple target messenger RNAs in at least one microscopy sample by in situ hybridization using sets of oligonucleotide probes. Also disclosed are methods to provide corresponding sets of oligonucleotide probes for target nucleic acid sequences.
