Life Science Buffers
IBI SCIENTIFIC 3P (EDTA) SOLUTION, 100 mL
IBI 0.5MEDTA solution (pH 8.0)is ideal for biochemistry and molecular biology applications requiring a chelator of divalent metal ions. Ethylenediamine tetraacetic acid solution can be used to elucidate the role of antigen retrieval in immunostaining of ethanol fixed smears.
Sigma Aldrich Fine Chemicals Biosciences Glycine Buffer Solution | 100ml
Glycine is used as a bulking agent buffers. Glycine at low concentrations prevents pH decrease in solutions. It also stabilizes a protein when present in an amorphous state.

Apexbio Technology LLC Annexin V-HF488/PI Apoptosis Kit 20assays
Annexin V is a Ca2 -dependent phospholipid-binding protein that specifically binds to phosphatidylserine (PS) Normally PS is localized on the inner leaflet of the cell membrane lipid bilayer During the early stages of apoptosis PS translocates from the inner leaflet to the outer surface of the cell membrane exposing it to the extracellular environment Due to Annexin V s high affinity for PS fluorescently labeled Annexin V (HF488) can be used as a fluorescent probe to detect apoptotic cells through flow cytometry or fluorescence microscopy with staining taking only 10-20 minutes Propidium iodide (PI) selectively binds double-stranded DNA and yields a red fluorescence PI is membrane-impermeable in healthy cells but can penetrate the membranes of late apoptotic and dead cells staining their nuclei Simultaneous staining with Annexin V-HF488 and PI enables differentiation between early apoptotic late apoptotic and dead cells
ILEX LIFE SCIENCES LLC GELATIN SOLUTION 2.0 6 X 100ML
PAN-Biotech Gelatin Solution 2% in DPBS, w/o: Ca, Mg (6 x 100 ml). DESCRIPTION: PAN-Biotech Gelatin Solution 2% in DPBS, w/o: Ca, Mg for laboratory research applications. Gelatin is a heterogenous mixture of water soluble proteins of high average molecular weight present in collagen. The proteins are extracted by boiling skin, tendons, ligaments, or bones in water. APPLICATION: Applications using gelatin include coating cell culture plates to improve cell attachment for a variety of cell types, addition to PCR to stabilize Taq DNA Polymerase, and use as a blocking agent in Western Blotting, ELISA, and immunohistochemistry. In bacteriology, gelatin can be used as a component of culture media. STORAGE: +2-8°C. MANUFACTURER: PAN-Biotech GmbH. COUNTRY OF ORIGIN: Germany.

Apexbio Technology LLC Annexin V-APC Reagent 20tests
Annexin V is a Ca2 -dependent phospholipid-binding protein that specifically binds phosphatidylserine (PS) Under normal conditions PS is located on the inner side of the plasma membrane lipid bilayer however during early apoptosis PS translocates from the inner leaflet to the outer surface of the cell membrane becoming exposed to the extracellular environment Annexin V has a high affinity for PS Fluorescent (APC)-labeled Annexin V serves as a fluorescent probe enabling detection of apoptotic cells using flow cytometry or fluorescence microscopy The staining procedure takes only 15-30 minutes to complete Use of this reagent requires additional purchase of 10X Binding Buffer (Catalog no K2284) To further characterize different apoptosis stages Annexin V can be combined with nuclear dyes such as 7-AAD DAPI PI or SYTOX Green These nuclear dyes specifically bind double-stranded DNA generating fluorescence Normally they cannot penetrate intac
Apexbio Technology LLC Protease Inhibitor Cocktail for bacterial cell extracts (100 X in DMSO) 50x(1ml A 1ml B)
Under stable environmental conditions endogenous protein synthesis and degradation are balanced thus maintaining stable cellular protein levels Cell crude extracts contain numerous endogenous enzymes such as phosphatases and proteases that can degrade proteins in the extracts During in vitro protein extraction from cells and tissues protein synthesis practically ceases while protein degradation increases The optimal way to enhance yields of intact proteins is to add inhibitors for these known enzymes The Protease Inhibitor Cocktail for bacterial cell extracts (100X in DMSO) is designed for bacterial extracts to enhance the stability of proteins This cocktail inhibits proteases responsible for degrading non-phosphorylated or phosphorylated protein substrates This Protease Inhibitor Cocktail is provided as a ready-to-use solution and it is formulated in DMSO
