ANTIBIOTIC A23187 

(Calcium Ionophore A23187) 

Free Acid 

White crystalline solid. 

Antibiotic A23187 is an antibiotic which demonstrates weak in vitro 

activity against gram-positive bacteria and fungi. It also has the ability 

to form stable complexes with divalent cations, increasing their ability 

to cross biological membranes, thus giving A23187 properties as an 

ionophore. Its U.V. and fluorescence spectral properties allow this 

calcium ionophore to be useful as a cytoplasmic free calcium ion probe. 

A23187 does exhibit toxicity and is a potential health hazard, so caution 

should be used when handling, in accordance with normal procedures for 

handling toxic compounds.

AURORA BLOCKING REAGENT 

Aurora Blocking Reagent is a highly purified casein-based blocking 

reagent specifically selected to provide the highest signal to noise 

performance in chemiluminescent applications using 1,2-dioxetane 

enzyme substrates such as MP’s StarLight. Aurora Blocking Reagent 

is superior to both dried milk and BSA, and unlike other casein-based 

blocking reagents is essentially biotin-free. Suggested working 

concentration is 0.2% (w/v) for immunoassays and protein detection on 

membranes (neutral nylon, nitrocellulose and PVDF). For best results, 

use of MP Biotrans, Biotrans(+) and Biotrans PVDF membranes are 

recommended.

AURORA SOUTHERN BLOT KIT For 

Chemiluminescent Nucleic Acid Detection 

Capacity: 10-20 blots or 50-100 blots 

(10x10 cm membrane) 

The Aurora Southern Blot Kit is a highly sensitive and versatile 

NON-isotopic chemiluminescence-based system for the detection 

of biotinylated nucleic acids in Southern and Northern blotting. This 

system offers convenience and speed over isotopic methods by utilizing 

the StarLight high performance chemiluminescent substrate and 

ActiBind-AP streptavidin-alkaline phosphatase conjugate for maximum 

signal intensity and low background results. As little as 1 pg of hybridized 

DNA and even sub-picogram quantities of biotinylated DNA bound to the 

membrane have been detected. Exposures require less than 60 minutes 

on either standard X-ray or instant film. The chemiluminescence emission 

will last for several days permitting multiple exposures and easy stripping 

and reprobing. 

Kit Contents: 

• StarLight substrate 

• ActiBind-AP 

• Aurora Blocking reagent 

• Diethanolamine 

A complete protocol booklet is supplied with each kit.

BATROXOBIN 

(EC 3.4.21.29) 

From: Bothrops atrox 

Activity: 120 BU/mg 

Unit Definition: the clotting time of bovine fibrinogen following the 

addition of ~0.2 ml batroxobin is recorded and converted into batroxobin 

units (BU) using the standard curve developed with the first British 

Standard, lot 75/527. 

Batroxobin coverts fibrinogen to fibrin through the cleavage of the Arg- 

Gly bonds of the-chain, resulting with fibrinopeptide A release. It 

will 

not be inactivated by thrombin inhibitors.

sCD14 ELISA KIT 

The sCD14 kit is a sandwich enzyme immunoassay for the determination 

of soluble CD14 in human serum, plasma, liquor, synovial fluid, urine, and 

cell culture supernatants. An anti-CD14 oligoclonal antibody is absorbed 

to polystyrene microtiter wells. Soluble CD14 present in the sample or 

the standard binds to the antibodies on the coated well. A biotinylated 

anti-CD14 monoclonal antibody directed against another epitope on the 

CD14 molecule is simultaneously added. After washing, a streptavidin 

peroxidase conjugate binds to the bound complex, completing the 

sandwich. Unbound conjugate is removed by washing, and the substrate 

solution is added to the wells. A colored product is formed in proportion 

to the amount of CD14 present in the sample. The kit is a 12 x 8 format.

CELLAGEN BEADS 

Cellagen Microspheres for Tissue Culture 

Cellagen Beads are prepared from bovine corium insoluble collagen 

by pepsin treatment. The collagen is then purified and formed into 

microsphere beads, approximately 100-400m. Since the Cellagen 

Beads consist of collagen fibril, culture conditions very similar to those in 

vivo may be carried out. Cellagen Beads have been used for culturing 

fibroblasts, epithelial cells, and osteoblasts.

CELLAGEN MEMBRANES 

A Permeable Collagen Film for Tissue Culture 

Cellagen Membranes are permeable collagen films developed for tissue 

culture use that permit the characteristic permeation of substances such 

as absorption of nutrients and exhaustion of metabolites through the 

membrane. Cellagen Membranes are especially effective on epithelial 

cell culture since they allow the best utilization of cell polarization. 

Also, long-term cultures can be done in keeping with the differentiated 

phenotypes in the living body. Additionally, since two types of cells can 

be cultured on both sides of the membrane, Cellagen may be used 

to study cell-cell interactions and for the basic study of hybrid artificial 

organs. 

Cellagen Membranes are made of highly purified, pyrogen-free, pepsinsolubilized 

collagen. The membranes are transparent, permitting easy 

observation of the cultured cells by phase contrast microscopy. 

Each set of membranes contains 5-discs with 33 mm diameter membrane, 

membrane bracket and culture dish.

CYCLOHEXIMIDE READY MADE 

Antibiotic solution 

Concentration: Approx. 100 mg/ml in DMSO (0.2 um filtered), 

microbial solution. 

Cycloheximide is an antibiotic product. Its main biological activity is 

translation inhibition in eukaryotes. The resulting inhibition of protein 

synthesis leads to cell growth arrest and death. Cycloheximide is 

used for selection of Cycloheximide resistant yeast and fungi strains, 

controlled inhibition systhesis for detection of short-lived proteins and 

superinduction of protein apoptosis induction or facilitation of apoptosis 

induction by death receptors.

1,4-DIACRYLOYLPIPERAZINE 

1,4-Diacryloylpiperazine is a unique polyacrylamide gel crosslinker. Used 

in place of Bis (N,N’-methylene-bis-acrylamide), 1,4-Diacryloylpiperazine 

provides increased gel strength, improved electrophoretic separation of 

proteins, and less background during silver staining.

DIACYLGLYCEROL KINASE INHIBITOR I 

(R59022; 6-[2-[4-[(4-fluorophenyl)phenyl-methylene]-1-piperidinyl] 

ethyl]-7-methyl-5H-thiazolo-[3,2-a]pyrimidin-5-one; DKI) 

The elevation of diacylglycerol became of major importance when 

diacylglycerol was shown to stimulate protein kinase C, making this lipid 

a candidate for a second messenger function in the signal transduction 

system. In intact cells, diacylglycerol is rapidly phosphorylated into 

phosphatidic acid by diacylglycerol kinase and reverses the protein 

kinase C activity. 

DKI was found to inhibit diacylglycerol kinase. In human red blood cell 

membranes and in intact platelets, the concentrations needed for half 

maximal inhibition ranged from 2 to 4 x 10 -6 M.
