NORADRENALINE ELISA KIT 

MP’s new noradrenaline ELISA kit offers greater convenience and 

sensitivity over the original ELISA system for the quantitative measurement 

of noradrenaline in plasma and urine. This new assay follows a typical 

sandwich assay format, requiring only 6 hours to obtain results. The 

reaction substrate is formazan and the wavelength is read at 492 nm. The 

kit is supplied with a standard 12 x 8 well plate.

ICN’s Oligo (dT) Cellulose has the advantages of specificity of binding, 

quantitative binding, dependability, simplicity of use and economy (can 

be recycled many times). 

Applications: 

• large scale isolation of mRNA 

• poly (rA) binding 

• [ 3 H] HeLa mRNA binding (see radiochemicals section) 

Binds chains up to 18 nucleotides long 

Binds minimum 100 A260/gm 

MP’s Oligo dT Cellulose has a 2 fold higher binding activity than 

most other products. Compare it with the material you are now

PEPTIDASE, TBL-1 

(Achromopeptidase) 

Source/species: Achromobacter lyticus M497-1 A heat-stable, 

bacteriolytic enzyme with lytic activity on both Gram-positive and 

Gram-negative organisms. Useful in preparation of protoplasts and 

spheroplasts, in preparation of bacterial enzymes, isolation of bacterial 

protein via lysis of wall. 

Heat Stability: When dissolved in 0.05M phosphate buffer solution(pH 

6.0) and heated at various temperatures for 10 minutes, the following 

results were obtained at 40°C or below: no change in activity 50°C: 95% 

residual activity 60°C: 75% residual activity 70°C: almost completely 

inactivated. 

Activity: 1,000 units/mg 

Supplied as a powder containing lactose as exipient. DNase free. 

Unit Definition: One unit of enzyme is defined as that which, when 

present in 1 ml of reaction solution, causes turbidity to decrease at the 

rate of 0.001 adsorbance units per minute under the standard conditions.

This product is an important member of the PF4 superfamily of 

chemoattractant proteins which has been shown to selectively attract T 

cells of the CD4+/CD45RO+ phenotype in vitro. Human RANTES, like 

human IL-8 and human MCAF/MCP1, should facilitate research of the

RAPID-Ag-STAIN4 

Rapid-Ag-Stain is an improved silver stain reagent kit developed to 

provide faster and more sensitive staining. Rapid-Ag-Stain is ideal 

for applications such as detection of proteins and nucleic acids in 

polyacrylamide gels, detection of trace polypeptides in complex samples, 

DNA and RNA, as a substitute for auto-radiography following CBB, and as 

a check of transfer efficiency. 

8 RAPID: Gels may be stained & visualized in less than 1 hour 

8 SENSITIVE: Up to 125 times more sensitive than CBB 

8 SIMPLE: Easy-to-follow 3 step procedure 

8 VERSATILE: For proteins, RNA, DNA, and 2-D Electrophoresis 

8 CONVENIENT: Enough reagent for 25 slab gels

REVERSE TRANSCRIPTASE 

From: Moloney Murine Leukemia Virus 

Murine Reverse Transcriptase is an RNA-dependent DNA polymerase 

that synthesizes a complementary DNA strand From: single-stranded 

RNA or DNA in the presence of a primer. This enzyme is multifunctional, 

containing both reverse transcriptase and RNase H activities (similar to 

AMV reverse transcriptase). 

Unit Definition: One unit is the amount of enzyme required to incorporate 

1 nmole of labeled dATP into acid-insoluble material in 10 min at 37°C. 

Supplied in a 50 mM Tris-HCl buffer, pH 8.0, 1 mM EDTA, 5 mM

SEROTONIN ELISA KIT 

This Serotonin ELISA kit provides materials for the quantitative 

determination of chemically derived serotonin in serum, plasma, urine, 

tissue homogenates, and cell culture supernatants. The assay procedure 

follows the basic principle of competitive ELISA whereby there is 

competition between a biotinylated and non-biotinylated antigen for a 

fixed number of antibody binding sites. The kit is a 12 x 8 format.

Also known as Mast Cell Growth Factor or c-kit ligand, SCF is a 

hematopoietic growth factor which stimulates the proliferation of bone 

marrow cells in 5-fluorouracil treated mice. It is believed to stimulate 

the proliferation of myeloid, erythroid and lymphoid progenitors in bone 

marrow cultures and has been shown to act synergistically with colony 

stimulating factors resulting in greater size and yields.

SULFAGEL4 PAGE STARTER KIT 

This convenient starter gel kit substitutes N,N’-Cystamine-bis-acrylamide 

(BAC) for N,N’-Methylene-bis-acrylamide as the cross-linking agent. BAC 

is a disulfide containing analog of Bis, and the disulfide bonds formed on 

polymerization become a part of the crosslinkage. The BAC-crosslinked 

gel may be redissolved by adding the sulfide bond reducing agent, 2- 

Mercaptoethanol (or dithiothreitol)

TRANSFERRIN (HOLO) 

From: Human Serum 

Not less than 95% total protein. Each vial (lyophilized) contains 10 mg 

transferrin. The contents of each vial readily dissolve in 1 ml water. 

Transferrin is a transport factor used in cell culture work to convey 

essential metabolites to cells. Transferrin binds iron and makes this 

element available to cells in a recognizable form. Cellular iron is utilized 

as an enzymatic cofactor in key metabolic pathways such as the generation 

of ATP. 

The metabolic transport functions of transferrin make it a strong promoter 

of cell growth in cell culture (for example, high transferrin levels in MP 

CELLect Iron-Supplemented Calf Serum facilitate growth performance 

similar to FBS; data sheet available upon request). 

Transferrin is frequently used as a supplement when culturing cells in 

Serum-Free Media.

TRITICUM VULGARIS AGGLUTININ (Wheat Germ 

Agglutinin) 

(WGA) 

Wheat germ lectin is isolated From: wheat germ (Triticum vulgaris) 

by affinity chromatography. WGA has specificity for N-acetyl--Dglucosaminyl 

residues and N-acetyl--D-glucamine oligomers. WGA 

agglutinates erythrocytes and lymphocytes non-specifically. 

Supplied as a lyophilized powder. 

Essentially salt-free and carbohydrate-free. 

Caution: has mitogenic properties.
