V5 or Pk-Tag (clone SV5-Pk1)
V5 tags can be incorporated into expression vectors of bacteria, fungi/yeast, insect or mammalian origin. Its presence does not interfere with the transport and selection of recombinant proteins in bacteria or mammalian cells. Both transmembrane and secreted proteins have been tagged with V5. V5 is usually a 14 aa tag; GKPIPNPLLGLDST; although a smaller 9 aa epitope tag (underlined in the above sequence) has also been successfully used. Additionally, the 9 aa tag may be used as a peptide to inhibit the binding of the antibody to its native protein.

His or His-6 Tag (clone AD1.1.10)
His tag (HHHHHH sequence) is widely used for purifying proteins expressed in bacteria, yeast, insect and mammalian systems. In Western blotting of bacterial extracts, our antibody MCA1396GA has been shown not to cross-react with any endogenous products.

c-myc Tag
This is a popular expression vector tag of 10 aa (EQKLISEEDL). c-myc tag is often used by researchers using two colour immunofluorescence applications. AbD Serotec has 2 monoclonal antibodies, clone 9E10 and JAC6, for use in many applications.

GFP (Green Fluorescent Protein)
GFP is a naturally occurring 27 kDa protein derived from the jellyfish Aequorea victoria that fluoresces green when exposed to blue light. It is particularly useful in fluorescence microscopy techniques. AbD Serotec has three anti-GFP antibodies. The polyclonal antibody (AHP975) detects wild type, recombinant and enhanced forms of GFP and is reactive in both prokaryotic and eukaryotic expression systems. The two monoclonal antibodies (OBT1643 and OBT1820) are suitable for use in a variety of applications.

S-Tag (clone SBSTAGb)
The S-tag is a 15 aa (KETAAAKFERQHMDS) truncated form of the S-peptide, used in variety of protein expression applications in mammalian cells. The antibody is suitable for detection of S-Tag by flow cytometry and ELISA.

Strep-Tag (clone Strep-MAB and Strep-Tag II)
Strep-tags are short 8 aa sequences (WSHPQFEK), especially useful for tagging membrane proteins, metalloproteins and sensitive protein complexes with multiple subunits. Clone Strep-MAB (MCA2488) is particularly suited to the capture of Strep-Tag II containing proteins in assays such as ELISA or BiaCore. Clone Strep-Tag II (MCA2489/2489P) recognizes both the N- and C-termini, as well as internal Strep-Tag II, and is ideal for Western blot applications.

Glutathione S-transferase Tag (Clone vpg66)
Glutathione S-transferase (GST) fusion vectors are often chosen for mammalian protein expression studies because they are inducible, and give high-level intracellular expression of genes or gene fragments.

Maltose Binding Protein Tag (Clone R29)
Maltose Binding Protein is often used in protein expression studies because it creates a stable fusion product. This allows for easy purification from bacterial extracts under mild conditions.

AntibodiesAntibodies are used in techniques such as confocal and fluorescence microscopy, flow cytometry, ELISA, ELISPOT, immunohistochemistry, western blotting and immunopreciptation. Select specific antigen reactivity, high specific affinity, low non-specific binding, monoclonal or polyclonal, primary or secondary antibodies and associated conjugates such as an enzyme or dye for visualization.Genome AnalysisGenomics, the study of genomes, includes functional genomics, evolutionary genomics and comparative genomics. There are many genomic technologies such as DNA sequencing of whole genomes, computational biology and bioinformatics. DNA and nucleic acids must be isolated and concentrated from cells for analysis with kits, automated analyzers and software. Other useful technologies for studying genomics include PCR, microarrays and electrophoresis.ELISAEnzyme-linked immunosorbent assays (ELISA), also known as enzyme immunoassays (EIA), are used for the detection and quantification of proteins, peptides and antibodies in a sample. ELISA often comes in kit format, with pre-selected antibody pairs to detect specific proteins or biomarkers of diseases such as diabetes and obesity, or cardiovascular and neurological disorders. Detection is made possible with chemiluminescent, fluorescent or colorimetric substrates and detection instruments such as microplate / ELISA readers. Other kits available include: Enzyme-linked immunospot (ELISPOT) assays for the quantification of protein-producing cells and chemiluminescent immunoassays (CLIA) kits. Find the best ELISA kits and products in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Flow Cytometry / Cell CountingFlow cytometers are used to count, sort and examine multiple characteristics of cells. Other cell analysis equipment includes image cytometers, cell counters, fluorescence-activated cell sorters (FACS), magnetic-activated cell sorters (MACS), and a range of flow cytometry assay kits. Flow cytometers can reveal information on cell viability, cell proliferation, apoptosis and cell cycle progression, as well as identify cell populations and intracellular or cell-surface molecules. Additionally, some flow cytometers, known as FACS, have an additional sorting function after analysis. Cell counters and image cytometers count live and dead cell populations and can also conduct cell proliferation assays.

The purification process typically involves subcellular or membrane protein extraction with cell lysis kits, separation of proteins from cell debris by filtration or spin columns, and the isolation of proteins of interest from other proteins and impurities with affinity purification (including fusion protein tags and antibody binding proteins A, G and L), immunoprecipitation or chromatographic methods, such as ion exchange, size exclusion and immobilized metal affinity chromatography. All purification methods come in multiple formats for your laboratory needs, including agarose or magnetic beads, resins, columns and filter plates.
