Catalog Number: (BOSSBS-0362R-A680)
Supplier: Bioss
Description: Protein A is a 40-60 kDa surface protein originally found in the cell wall of the bacteria Staphylococcus aureus (SPA). SPA binds proteins from many of mammalian species, most notably IgGs, and helps inhibit phagocytic engulfment and acts as an immunological disguise via this type of interaction, thus the bacteria will disrupts opsonisation and phagocytosis. SPA is known to bind with Fc region of immunoglobulins preferentially through interaction with the VH3 variable region of the heavy chain. SPA has been shown to bind with high affinity to human IgG1 and IgG2 as well as mouse IgG2a and IgG2b, whereas bind with moderate affinity to human IgM, IgA and IgE as well as mouse IgG3 and IgG1. SPA is often produced in E. coli and is practically coupled to other molecules such as enzymes, biotin, radioactive iodine for use in immunology and other biological research. SPA is also immobilised onto solid supports such as agarose beads for total IgG purifying or interest protein or protein complex identifying in immunoprecipitation studies.

Catalog Number: (786-271)
Supplier: G-Biosciences
Description: SDC™ (Steroid/Drug/Compound) Immobilisation Kit is designed for the immobilisation of steroids, drugs and chemical compounds that lack primary amines, sulfhydryls, carbonyls and other common coupling groups to a solid-phase agarose support for the use in affinity purification. The kit uses Immobilised DADPA (diaminodipropylamine) resin to bind steroids, drugs and chemicals through their active hydrogens.

Catalog Number: (BSENR-1313-100)
Supplier: Biosensis
Description: Maltose binding protein (MBP) is encoded by the malE gene of E.coli. MBP is often used in protein expression studies because it creates a stable fusion product that does not appear to interfere with the bioactivity of the protein of interest. It also allows for its easy purification from bacterial extracts under mild conditions.

Description: Fluor de Lys® Substrate is a highly sensitive and convenient alternative to radiolabeled, acetylated histones or peptide/HPLC methods for the assay of histone deacetylases. The Fluor de Lys® Substrate, which comprises an acetylated lysine side chain, is incubated with a sample containing HDAC activity (nuclear or cellular extract, purified enzyme, bead-bound immunocomplex, etc.). Deacetylation of the substrate sensitizes the substrate so that, in a second step, treatment with the Fluor de Lys® Developer produces a fluorophore. Histone deacetylases from all known classes have been successfully assayed with the Fluor de Lys® Substrate. These include human HDACs 1, 2, 3 and 8 (class I), human HDACs 4 and 9 (class II) and the sirtuins yeast Sir2, human SIRT1 and human SIRT2 (class III; reaction must include the sirtuin substrate NAD+). The substrate is cell-permeable and serves as the basis for the HDAC Cellular Activity Assay Kit (Prod. No. BML-AK503). NOTE: Must be used in conjunction with Fluor de Lys® Developer (Prod. No. BML-KI105). Sufficient for 100-1000 assays of HDACs or sirtuins (50 µl reaction volume, 50-500 µM (substrate).

Description: These borosilicate glass filters are ideal for measuring landfill leachate composition with a TCLP test. They can also be used for DNA binding and purification, filtering finely precipitated proteins and filtering biochemical solutions, fluids, and nucleic acids.

Supplier: Biotium
Description: Protein phosphorylation is a fundamental event in the regulation of a large number of intracellular processes. Phosphorylation of specific tyrosine residues is the result of activation or stimulation of their respective protein tyrosine kinases. The phosphorylated proteins can be auto-phosphorylated kinases or certain cellular protein substrates. Tyrosine-phosphorylated proteins are involved in signal transduction and in the regulation of cell proliferation. Antibody to phosphotyrosine provides an excellent tool for the detection, characterization, and purification of phosphotyrosine containing proteins. This MAb shows no cross-reaction with other phosphoamino acids and is superb for multiple applications including staining of formalin/paraffin tissues.

Description: The Protein A IgG Purification Kit is useful for routine purification of antibodies. Samples containing IgG are incubated with immobilised Protein A in a buffer that facilitates binding. After non IgG components are washed from the column, the bound IgG is recovered by elution. The supplied buffers provide for maximum immunoglobulin binding and elution efficiency with the Protein A column.
