Description: Neuraminidase (Sialidase: Acylneuraminyl hydrolase; EC 3.2.1.18) From Arthrobacter ureafaciens lyophilised powder with salts. The salts are composed of sodium-potassium phosphate to give a solution of 10 mM phosphate buffer (pH 7) when enzyme is reconstituted with water to make activity of 1 unit per ml. Activity: >60 units/mg protein for NAN-lactose >25 units/mg protein for bovine submaxillary mucin >20 units/mg protein for colominic acid Protein is determined by the method of Lowry et al. with bovine albumin as a standard.6 Unit definition: One unit will liberate 1,0 µmole of N-acetyl-neuraminic acid (NANA) per minute at pH 5,0 at 37 °C, using either one NAN-lactose, bovine submaxillary mucin, or colominic acid as a substrate.

Description: The efficient removal of unincorporated dNTPs, salts and enzymes after any PCR is detrimental to the success or failure of downstream applications, such as genotyping, Sanger, and Next Generation Sequencing. The AxyPrep™ Mag PCR Clean Up Kit utilises a paramagnetic bead technology for rapid high throughput purification of PCR products. Additionally, the AxyPrep™ Mag PCR Clean Up Kit employs an optimised buffer to selectively bind PCR amplicons 60 bp and larger to paramagnetic beads, providing end users flexibility and high recovery options. The protocol comprises binding, washing and eluting steps, where primers, nucleotides, salts and enzymes in the reaction mixture are efficiently removed leaving a purified PCR product that is essentially free of contaminants. No centrifugation or filtration steps are required, allowing the process to be adapted to multiple commercially available automation platforms.

Description: CAPS is a zwitterionic biological buffer which has minimal reactivity with enzymes or proteins and minimal salt effects. CAPS buffer is widely used in Western and immunoblotting experiments as well as protein sequencing and identification. The high pH of this buffer makes it useful for the transfer of proteins with a pI > 8,5.

Description: These Polycap™ SPF capsule filters are optimised for prefiltration applications. They are typically used upstream of a Polycap™ AS or Polycap™ TC capsule during enzyme, nutrient media or buffer filtration.

Supplier: Biosensis

Description: The Biosensis Mouse and Rat proNGF Rapid enzyme-linked immunosorbent assay (ELISA) Kit is a sandwich ELISA that allows the quantification of rodent full-length proNGF protein in less than 4 hours in cell culture supernatants, cell lysates and tissue homogenates only if used as directed. This ELISA Kit has also successfully been used on mouse urine samples (Ryu JC et al., 2018). Please refer to the kit protocol for specific use instructions for each substrate application.

This ELISA kit contains a recombinant mouse proNGF standard expressed in E.coli and consists of a pre-coated anti-proNGF capture antibody, a biotinylated anti-proNGF detection antibody and horseradish peroxidase (HRP)-conjugated streptavidin. The addition of a substrate (3,3',5,5'-tetramethylbenzidine, TMB) yields a colored reaction product which is directly proportional to the concentration of proNGF present in samples and protein standards. A proNGF positive control (QC sample) is provided to assure consistent assay performance. This ELISA kit detects rat proNGF due to high degree of homology (96%) with mouse proNGF based on amino acid sequence, and the ability of this kit in detecting proNGF in rat PC12 cell lysates and rat brain tissue homogenate. In the absence of a true rat proNGF standard, results may be expressed as 'mouse proNGF equivalents'. This ELISA kit shows only 20% reactivity with the human form of proNGF and is therefore not suitable to quantify human proNGF. No cross-reactivity was observed with mature mouse NGF and full-length proBDNF when tested in assay buffer.

The antibodies used in this ELISA kit bind epitopes within the pro-domain (capture) and mature domain (detection) of the protein, thus this ELISA assay does not detect the pro-domain peptide. This kit has not been tested for other applications. Sufficient amount of proNGF standard is supplied to allow for spike- and recovery experiments in order to validate this ELISA assay for other sample matrices if required.

Description: Storage: Store at Room Temperature (15 - 30 °C)
Glycerol is used both in sample preparation and gel formation for polyacrylamide gel electrophoresis. Glycerol (5-10%) increases the density of a sample so that the sample will layer at the bottom of a gel’s sample well. Glycerol is also used to aid in casting gradient gels and as a protein stabilizer and storage buffer component. Glycerol is used in the concentration and storage of enzymes. Also prevents back-diffusion and protein samples into the buffer. Ideal for use as a cryoprotectant.
