STEMCELL Technologies EasySep™ Human EpCAM Positive Selection Kit II, For processing: 1 x 10^9 cells
The EasySep™ Human EpCAM Positive Selection Kit II is designed to isolate EpCAM+ cells from fresh or previously frozen human mammary epithelial cell preparations by immunomagnetic positive selection. Desired cells are targeted with antibody complexes recognizing EpCAM and dextran-coated magnetic particles. The cocktail also contains an antibody to human Fc receptor to minimize nonspecific binding. Labeled cells are separated using an EasySep™ magnet without the use of columns. Cells of interest remain in the tube while unwanted cells are poured off. The EpCAM+ fraction contains luminal cells, luminal-restricted, and bipotential progenitor cells.This product replaces the EasySep™ Human EpCAM Positive Selection Kit (Catalog #18356).
Alkali Scientific LB Agar (Miller) w/Ampicillin & Chloramphenicol 20mL Plate, 10/Pk
LB Agar (Miller) with Ampicillin and Chloramphenicol is a dual selection medium designed for molecular biology workflows requiring maintenance of two resistance markers. Each plate contains 20 mL of high salt Miller formulation Lysogeny Broth agar supplemented with both antibiotics. This medium is commonly used in co transformation experiments where a single E. coli cell must maintain two compatible plasmids, such as an expression vector and a reporter plasmid. It is also suitable for specialized strains like BL21(DE3)pLysS or Rosetta that carry helper plasmids conferring chloramphenicol resistance. Ampicillin maintains plasmid selection while chloramphenicol ensures retention of the helper plasmid, allowing stable propagation of both genetic elements during cloning and protein expression experiments.

IW Tremont Co Inc Grade CFP40 Cellulose filter paper, 15.0cm dia. 100/pk Quantitative grade
LabExact Grade CFP40 is a quantitative cellulose filter paper demonstrating medium particle retention and flow characteristics, making it suitable for a wide range of general quantitative procedures in both liquid and gas applications. With an approximate particle retention of 8µm, this grade is commonly specified for standard environmental testing, including soil sample analysis and the collection of trace elements and radionuclides in air samples. The media is also used in liquid food testing for sediment determination and in the analysis of cements, slurries, and other particulate‑containing materials, and is frequently selected for sample preparation prior to spectrophotometric analysis where consistent retention and minimal residue are required. Grade CFP40 exhibits an extremely low ash content of less than 0.01% and has a nominal thickness of 0.200mm, supporting predictable flow behavior and reliable performance in routine quantitative laboratory procedures.

Sigma Aldrich Fine Chemicals Biosciences fatty Acid Methylation Kit
Methyl esterification of fatty acids is commonly done prior to gas chromatography analysis to prevent peak tailing and to increase sample volatility. However the conventional esterification procedure requires specialized equipment and high technical skill. By using the fatty Acid Methylation kit that employs a new reaction technique followed by the fatty acid methyl ester purification kit (MAK225) fatty acid methyl esterification is greatly simplified.
Sigma Aldrich Fine Chemicals Biosciences High Pure Plasmid Isolatio
Nucleic acids bind to the surface of the glass fiber fleece in the presence of a chaotropic salt (guanidine HCl). This allows the High Pure filter tube to specifically immobilize nucleic acids (both DNA and RNA) while they are freed of contaminants.Capacity The High Pure Spin filter Tubes hold up to 700 muL sample volume.Sample 0.5 - 4.0 mL cultures of E. coli (harvested at a density of 1.5 - 5.0 A 600 units/mL)
Sigma Aldrich Fine Chemicals Biosciences Glutathione SepharoseR 4B
Glutathione Sepharose(R) 4B is designed for high capacity single-step purification of Glutathione S-Transferase (GST) tagged fusion proteins.GST-tagged proteins and other glutathione S-transferases or glutathone-dependent proteins can be purified directly from bacterial lysates using Glutathione Sepharose(R) 4B. Proteins are eluted under mild non-denaturing conditions that preserve protein antigenicity.
