Recirculating Chillers
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 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 ApiezonR grease1EA
for low vapor pressure sealing and lubrication in high vacuum applications.
Sigma Aldrich Fine Chemicals Biosciences Albumn-fluorescen soth250MG
Albumin makes up 60% of the plasma protein which is produced by the liver. It regulates colloid osmotic pressure. Albumin is implicated in the transportation distribution and metabolism of fatty acids thyroid hormones and drugs. It reduces weight gain blocks pulmonary edema decreases ascites and lowers tissue edema.
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.
Sigma Aldrich Fine Chemicals Biosciences Jacketed beaker1EA
One upper and one lower hose connection on opposite sides. Without pouring spout. A 3/8 in. I.D. hose is specified. A vacuum is not used with this product. Hot or cold liquids are circulated through the jacket to control temperature within the beaker.
Sigma Aldrich Fine Chemicals Biosciences RNAzolR RT for processing
RNAzol RT is a quick and convenient reagent for use in thesingle-step isolation of total andsmall RNA from biological samples of human animal plant yeast bacterial and viral origin. A convenient single-step liquid phase separation results in the isolation of RNA from DNA protein polysaccharides and other molecules. RNAzol(R) RT can be used to isolate separate fractions of mRNA and micro RNA or to isolate total RNA containing all classes of RNA in a single fraction. This product a mixture of guanidine thiocyanate and phenol in a monophase SOLUTIONon effectively dissolves DNA RNA and protein on homogenization or lysis of tissue sample. Addition of water to the mixture allows for the precipitation of DNA proteins polysaccharides and other molecules which can then be removed by centrifugation. RNA can then be isolated by alcohol precipitation washing and solubilization. Chloroform-induced phase separation is not necessary. One mL of RNAzol(R) RT is sufficient to isolate RN
Sigma Aldrich Fine Chemicals Biosciences ProteoSilverTM Plus Silver
Conveniently packaged extremely stable and highly sensitive ProteoSilver(TM) Plus Silver Stain Kit is an ideal product for any protein scientist. Similar to ProteoSilver (PROTSIL1) this kit contains prepared SOLUTIONons of silver staining reagents along with detailed instructions to achieve optimal results. With a detection limit of 0.1 ng/mm2 of protein (BSA) and an extremely low background ProteoSilver Plus leads to superior detection of low abundance proteins.ProteoSilver Plus is also MALDI-MS compatible and does not contain glutaraldehyde which crosslinks lysine residues resulting in inaccurate spectra. ProteoSilver Plus Silver Stain Kit contains two additional reagents for destaining an excised protein spot for those wishing to perform further characterization through tryptic digestion and MALDI-MS analysis.
