Protein Labeling Reagents
Enzo Life Sciences BIO-PROBE 3'-Oligonucleotide labeling kit with bio-16-ddUTP (25Reactions)
Terminal labeling is an ideal procedure for the labeling of oligonucleotides with haptens such as biotin or fluorescein. An oligonucleotide can be synthesized using standard, commercially available reagents and labeled after synthesis in a simple and reproducible enzyme reaction.The BIO-PROBE 3'-Oligonucleotide Labeling Kit with Bio-16-ddUTP contains all reagents required for terminal labeling of oligonucleotides with biotin except the oligonucleotides to be labeled. The BIO-PROBE 3'-Oligonucleotide Labeling Kit provides maximum flexibility for labeling oligonucleotides approximately 15 to 100 nucleotides in length. A standard reaction will label up to 100 picomoles (1 µg of a 30-mer oligonucleotide sequence). A complete kit contains two component packs that are available separately: a Reagent Pack and a Bio-16-ddUTP Dideoxynucleotide Pack. Both packs contain sufficient reagents for 25 labeling reactions. Applications: Southern Blot, Northern Blot, ISH , Dot Blot.
Cell Biolabs Inc OxiSelect™ Oxidative DNA Damage Quantitation Kit (AP Sites), 50 assays
Among numerous types of oxidative DNA damage, apurinic/apyrimidinic (AP or abasic) site is one of the prevalent lesions of oxidative DNA damage. Abasic sites arise in DNA at a significant rate by spontaneous base loss as in depurination, by DNA oxidation, or by the action of DNA glycosylases. The OxiSelect™ Oxidative DNA Damage Quantitation Kit (AP sites) uses an Aldehyde Reactive Probe (ARP) to react specifically with an aldehyde group on the open ring form of AP sites. This allows for the AP sites to be tagged with biotin which is later detected with Streptavidin-Enzyme conjugate. The quantity of AP sites in unknown DNA sample is determined by comparing its absorbance with a standard curve generated from the provided DNA standard containing predetermined AP sites. The kit has a detection sensitivity range of 4 to 40 AP sites per 1 x 105 bp. Each kit provides sufficient reagents to perform up to 50 assays for unknown samples, excluding the standard curve.
Enzo Life Sciences Rhod-2 AM (ultra pure) (1mg). CAS: 129787-64-0
Rhod-2 AM has the longest fluorescent emission signal of the commonly used calcium indicators. It contains a rhodamine-like fluorophore, making it suitable for use with argon and krypton laser excitation sources. Rhod-2 signal intensity one of the strongest of all the calcium probes. Rhod 2 is especially suitable probe for intracellular calcium monitoring by confocal laser-scanning microscopy and flow cytometry. The dissociation constant of Rhod 2 with calcium is among the highest of all the fluorescent calcium probes, providing a wider range for monitoring calcium concentration. Wavelength Maxima: Excitation 549nm, Emission 578nm. Alternative name: 1-[2-Amino-5-(3-dimethylamino-6-dimethylammonio-9-xanthenyl)phenoxy]-2-(2-amino-5-methylphenoxy)]ethane-N,N,N',N'-tetraacetic acid, tetraacetoxy methyl ester . Br. Purity: ≥90% (HPLC). Solubility: Soluble in DMSO. Long Term Storage: -20°C.
