Heparin, fluorescent U5d ....................................................
Fluorescent Heparin- A Sodium Heparin from Porcine Intestinal Mucosa with a molecular weight
that ranges from 3,000 to 30,000 daltons. The strength, quality and purity meet pharmaceutical
specifications. Porcine raw materials test negative for Prion agents due to an approved method of
purification that removes TSE and viral agents. The activity of Sodium heparin averages 179-181u/
mg. This Sodium heparin is bound to Fluorescein Isothiocyanate. Used in studies on metabolic fate
of exogenously administered heparin. Excitation max: 491nm Emission max: 516nm

Methyl Benzoylformate H7ad ................................................
C 6 H 5 COCO 2 CH 3
Synthesis intermediate, photoinitiator for UV curable systems.
Nadic Methyl Anhydride (NMA) [25134-21-8] HO6g .............................
MW 178.2 n25
D 1.505
Liquid anhydride for curing epoxy resins. This material is a mixture of methyl isomers
of methylbicyclo[2.2.1]hept-5-ene-2,3-dicarboxylic anhydride. The larger the
proportion of NMA used in the epoxy resin formula, the harder the resultant block.
5-Amino-1,10-phenanthroline [54258-41-2] U5g ................................
MW 195.19 mp 259-260°
Used for forming metal complexes to catalyze biological reactions. Also useful for protein
adsorption when coupled to CM-cellulose.

MW 180.20 mp 114-117° C 12 H 8 N 2
Yellow flakes. For the determination of Fe, Pd, V and detection of Fe, & V.
Prionex ® A2m ..............................................................
Prionex is a polypeptide fraction of highly purified dermal collagen of porcine
origin with excellent protein stabilizing properties. Prionex is prepared by partial
hydrolysis under mild conditions. An extremely pure form of gelatine type A free
from cartilage, bone and plasma components. Due to the chemical nature and
the standardized quality, Prionex can be used as an inert protein stabilizer in
any kind of application and as an additive for cell culture media. No risk of BSE,
MCD and HIV infective agents. Prionex solution 10% is a clear yellow, sterile
solution. pH 6.0-7.5
