5X Phosphate Buffer, pH8 (250 mM Phosphate buffer pH 8, 1.5 M NaCl).

Phosphate Buffer, pH8 is a mix of Sodium Phosphate dibasic (Na2HPO4) and Monosodium Phosphate (NaH2PO4). This buffer is the basis for wash and elution buffers for protein purification through His-tag.

The Carbenicillin (disodium) EZ Pak™ is the fastest and easiest way to make a set amount of sterile carbenicillin (disodium) solution. The kit includes pre-weighed carbenicillin (disodium) powder, a sterile filter, and a sterile container for the filtered solution. No need to calculate, simply add the stated amount of deionized H2O, filter, and pour into the labeled bottle for easy usage. The EZ Pak™ includes high quality GoldBio carbenicillin (disodium) and the sterile solution is ready for tissue culture, bacterial media, or any number of uses.

NDSB-201 is a protein specific additive that can be used to help solubilize and stabilize proteins at non-denaturing concentrations while preventing protein aggregation.

NDSB-201 is a member of a group of nondetergent sulfobetaines. These zwitterionic compounds can reduce aggregation and aid in refolding and renaturing of proteins found in bacterial expression systems and in inclusion bodies. Unlike detergents such as CHAPS, NDSBs are nondenaturing, even at higher concentrations and have been shown to increase the yield efficiency of membrane and nuclear proteins, among others.

10 x 10 cm tube floater with a capacity for 10 1.5 mL tubes and 10 .6 mL tubes.

Coelenterazine 400a is a derivative of coelenterazine and is a good substrate for Renilla reniformis luciferase (RLuc), but does not oxidize well with Gaussia (GLuc). It is the preferred substrate for BRET (Bioluminescence Resonance Energy Transfer) since its emission maximum of 400nm has minimal interference with the GFP emission.

Ciprofloxacin is a second generation fluoroquinolone antibiotic targeting a broad-spectrum of bacteria and mycoplasma. It is nalidixic acid analog and has few known resistant strains. Ciprofloxacin is also effective as a plant fungicide and is sparingly soluble in water. GoldBio also offers a water soluble version, Ciprofloxacin HCl, for easier use in specific applications.

Imidazole is a planar 5-membered ring. It is a highly polar, highly water soluble amphoteric compound. Imidazole is often used to elute tagged proteins bound to metal ions attached to the surface of beads in a chromatography column by displacing the His-tag from the metal ion and freeing the His-tagged proteins.

His-Tag Buffer Set includes:

- 250 mL Wash Buffer (50mM Phosphate Buffer pH 8, 300mM NaCl, 10mM Imidazole)- 50 mL Elution Buffer (50mM Phosphate Buffer, 300mM NaCl, 500mM Imidazole)

Designed for use with Goldbio Nickel and Cobalt Agarose resins, but it can be used with most standard His-tag purification resins.

GoldBio’s Illumination™ Firefly & Renilla Luciferase Enhanced Assay Kit is a combined luciferase assay allowing the sequential measurement of Firefly and Renilla luciferase activity in the same sample while still retaining the highest degree of sensitivity, reliability and linearity that you want in your assay. Firefly activity is measured first, then the Renilla Luciferase Assay Buffer is added to the sample to simultaneously extinguish all firefly luciferase activity to the level of untransformed cells and begins the Renilla luciferase activity. This great luciferase combo allows the sequential measurement of both luciferase assays in the same sample without additional hassle.

This kit is a flash-type luminescent assay, and requires measurement immediately after adding the detection reagents to the sample. The Enhanced Assay Kit includes our water soluble coelenterazine that is easier to use and store than other conventional coelenterazine products.

One Assay can be performed in a single tube or an individual well on a 96 well plate. The kits include enough Passive Lysis Buffer to perform the stated number of assays in plate sizes ranging from 96-well to 24-well.

Kit components

• 1X Passive Lysis Buffer
• Firefly Luciferase Assay Buffer
• Renilla Luciferase Assay Buffer
• GoldBio D-Luciferin
• GoldBio Enhanced Coelenterazine

CAPS is a zwitterionic buffering agent used in biochemistry and molecular biology. It is a cyclohexylamine buffer that is useful for a pH range of 9.7 – 11.1 and commonly used to study enzymatic processes above physiological pH. CAPS is an excellent buffer for the transfer of high molecular weight proteins to nitrocellulose membranes after SDS-PAGE. It is also used in protein sequencing. CAPS displays only weak or negligible complexation capabilities for some metals making it a suitable non-coordinating buffer for use in solutions containing metal ions. CAPS is suitable for use with the bicinchoninic acid (BCA) assay.

DAB tetrahydrochloride hydrate is a water soluble form of 3-3'-diaminobenzidine and is used to stain for peroxidase activity. The intensity of DAB staining can be increased with the addition of cobalt, nickel or silver ions.

PIPES sesquisodium salt is a buffering agent used in biochemistry and molecular biology that was selected and described by Good et al. It is a zwitterionic, piperazinic buffer that is useful for a pH range of 6.1 – 7.5. PIPES lacks the ability to form a significant complex with most metal ions and is recommended for use as a non-coordinating buffer in solutions with metal ions. PIPES has wide variety of applications and is commonly used in cell culture media, in protein crystallization, as a running buffer in gel electrophoresis, and as an eluent in isoelectric focusing and chromatography. This buffer is capable of forming radicals and is therefore not suitable for redox reactions. It is suitable for use in the bicinchoninic acid (BCA) assay.
