Sigma Aldrich Fine Chemicals Biosciences KiCqStartR SYBRR Green qPC
KiCqStart SYBR Green qPCR ReadyMix is a 2X concentrated ready-to-use reaction cocktail that contains all components except primers and template for real-time quantitative PCR (qPCR) This unique combination of proprietary buffer stabilizers and Hot-Start Taq DNA polymerase delivers maximum PCR efficiency sensitivity specificity and robust fluorescent signal using fast or conventional cycling protocols with SYBR Green qPCR.Highly specific amplification is crucial to successful qPCR with SYBR Green I dye technology because this dye binds to and detects any dsDNA generated during amplification. Hot-Start Taq DNA polymerase is antibody mediated to be inactive prior to the initial PCR denaturation step. The optimized formulation includes SYBR Green I dye an antibody-mediated Hot-Start Taq DNA polymerase dNPTs MgCl2 and proprietary buffers and stabilizers.
Sigma Aldrich Fine Chemicals Biosciences HisTrapTM High Performance
HisTrap(TM) HP columns are prepacked with Ni Sepharose(R) HighPerformance and designed for simple high-reSOLUTIONon purificationof histidine-tagged proteins by immobilized metal ion affinity chromatography (IMAC).HisTrap(TM) HP 1 mL and 5 mL columns are designed for simple one-step purification of histidine-tagged proteins. The columns are prepacked with Ni Sepharose(R) High Performance which has high binding capacity and low nickel ion leakage that ensures reliable capture of target protein in repeated IMAC purifications.HisTrap(TM) HP columns can also be used for the purification of tagged proteins containing shorter or longer polyhistidine tags such as (histidine)4 or (histidine)10. The shorter (histidine)4 will bind more weakly and the longer (histidine)10 will bind more strongly compared with (histidine)6. This difference in binding strength can be used during purification since (histidine)10 binds more strongly a higher concentration of imidazole can be added to the lysed ce
Sigma Aldrich Fine Chemicals Biosciences Human IfNL1 Interferon l
The Human IL-29 ELISA (Enzyme-Linked Immunosorbent Assay) kit is an in vitro enzyme-linked immunosorbent assay for the quantitative measurement of human IL-29 in serum plasma cell culture supernatants and urine.
Sigma Aldrich Fine Chemicals Biosciences Sera MagTM SpeedBeadsTM Bl
Sera-Mag(TM) SpeedBeads(TM) and Sera-Mag(TM) Carboxylate-Modified Magnetic Particles combine a fast magnetic response time and high binding capacity with a large surface area high sensitivity stability physical integrity and fast reaction kinetics. Covalent coupling of biomolecules such as proteins and nucleic acids to carboxyl groups on the surface is easily accomplished using our standard coupling technology. The core of the particle is made by a free radical emulsion polymerization of styrene and acid monomer. One (Sera-Mag(TM)) or two (Sera-Mag(TM) SpeedBeads(TM)) layers of magnetite are then coated onto this core while the surface is modified to minimize non-specific binding of proteins.
Sigma Aldrich Fine Chemicals Biosciences Protein A High Performance
protein A HP SpinTrap(TM) are designed for the enrichment of proteins of interest immunoprecipitation and the purification of monoclonal and polyclonal antibodies from cell lysates and biological fluids. Contain protein A Sepharose(R) HP.
Sigma Aldrich Fine Chemicals Biosciences Bouins solution
Bouin SOLUTIONon is a noncoagulant yellow stain fixative. It imposes shrinkage on tissues when used as preservative due to its picric acid component. It is majorly used in ureteroscopic biopsies. It preserves morphological and nuclear information in tissues upon fixation.

Sigma Aldrich Fine Chemicals Biosciences Dulbeccos Modified Eagles
The most basic formulation offered. This formulation is used by investigators who want to start with the essential components of DME and have the flexibility to optimize the formula for their own application.
Sigma Aldrich Fine Chemicals Biosciences MicrospinTM G 50 Columns C
MicroSpin(TM) G-50 columns are designed for the rapid purification of DNA for use in a wide range of applications including desalting buffer exchange removal of dye terminators from cycle sequencing reactions and removal of labelled nucleotides from DNA labelling reactions. Good product yield and purity is obtained with sample volumes from 12-50 ul. They are suitable for any DNA greater than 20 bases in length. They will not remove or denature enzyme.
Sigma Aldrich Fine Chemicals Biosciences ReadyShieldR Protease and
Protease and Phosphatase Inhibitor Cocktail has been optimized and tested for mammalian cellular and tissue extracts. It contains inhibitors with a broad specificity for serine cysteine acid proteases aminopeptidases L-isozymes of alkaline phosphatases and serine/ threonine protein phosphatases. Protease and Phosphatase Inhibitor Cocktail has been tested on extracts from various animal tissues such as human placenta and bovine liver and on extracts of A431 CHO and U937 cells. The cocktail is supplied as a ready-to-use SOLUTIONon using a proprietary non-freezing formulation. ReadyShield(R) PPC2020 is a non-freezing formulation that contains the same inhibitors as is the DMSO based cocktail PPC1010
Sigma Aldrich Fine Chemicals Biosciences Protein A-SepharoseR from250MG
Protein A-Sepharose when linked with antibody helps improving antigen binding capacity of IgG crosslinked to column matrices. In this case binding happens between Protein A and fc portion of the IgG molecule leaving antigen specific sites free.
