Supplier: Invitrogen
Description: Protein desalting spin columns are designed to desalt or exchange buffer of protein samples with volumes of 30 to 120 µL. These devices have exceptional desalting characteristics with ≥95% retention of salts and small molecules while providing excellent recovery of proteins greater than 7 kDa. Multiple samples can be processed in less than 5 minutes without cumbersome column preparation steps.
Supplier: Biotium
Description: Llama anti-rabbit CF™ dye conjugates are prepared by labeling affinity purified llama anti-rabbit IgG (H+L) with a selection of CF™ dyes. CF™ dyes offer combined advantages in brightness, photostability, and specificity compared other fluorescent dyes. Far-red fluorescent CF™647 (Ex/Em 650/665 nm) is brighter than Cy®5 and an excellent alternative to Alexa Fluor® 647 for antibody conjugates.

Catalog Number: (490007-384)
Supplier: Excel Scientific
Description: These sealing films are 203 m thick white vinyl films with 37m acrylic adhesive for use with white microplates. The sealing films may be applied to either the top or bottom of the plate.


Supplier: Excel Scientific
Description: A 140 m thick hydrophobic porous sealing film with medical-grade adhesive for tissue culture plates, bio-blocks, and 96-well plates where gas exchange is necessary for cell or bacterial growth.

Supplier: Biotium
Description: This conjugate is prepared by labeling F(ab’)2 fragment of goat anti-rabbit IgG (H+L) with CF™594 dye. CF™ dyes offer advantages in brightness, photostability, and specificity compared to other fluorescent dyes. Deep-red fluorescent CF™594 (Ex/Em 593/614 nm) is spectrally similar to Alexa Fluor® 594 and Texas Red® dye but yields much brighter protein conjugate, and has excellent photostability.

Supplier: Heathrow Scientific
Description: Nitrogen-free papers feature a very smooth surface for excellent sample recovery.

Catalog Number: (10018-136)
Supplier: Biotium
Description: Polyclonal anti-GST reacts with glutathione-S transferase (GST), a common expression tag used in molecular biology. This conjugate is prepared by labeling polyclonal goat anti-GST IgG (H+L) with CF™594 dye. CF™594 (Ex/Em 593/614 nm) is a deep-red dye spectrally similar to Alexa Fluor® 594 and Texas Red® dye but yields much brighter protein conjugates due to its high quantum yield and exceptional water solubility. CF™594 also has excellent photostability ideal for demanding applications, such as confocal microscopy and single molecule imaging.

Supplier: Excel Scientific
Description: The dispenser facilitates the quick and easy dispensing of film from a roll allowing microplates to be sealed three times faster than using sheeted films. Cost-effective replacement rolls are sold separately.

Catalog Number: (490017-180)
Supplier: Excel Scientific
Description: ThermalSeal RTS™ sealing films are based on 50 µm polyolefin films with 50 µm inert encapsulated silicone adhesive.

Supplier: Erie Scientific
Description: Slides are designed for the SHUR/Mark® etching labeling system and other automated labeling systems

Supplier: Excel Scientific
Description: SealPlate ColorTab adhesive sealing films consist of 50 m thickness clear polyester. They minimize evaporation, prevent spillage and contamination between wells, and provide a secure seal for ELISA, EIA, and similar assays.

Supplier: Excel Scientific
Description: Easily pierceable, 70 m thick, polyethylene with acrylic adhesive, EZ-Pierce sealing films allow direct sample recovery with single or multichannel pipettors and robotic probes.

Supplier: Excel Scientific
Description: AlumaSeal CS sealing films are specially formulated aluminum foil sealing films with an adhesive that withstands cold storage at temperatures to -80 °C.

Supplier: Excel Scientific
Description: A 36 µm soft non-permeable aluminum foil sealing film with strong medical-grade adhesive, AlumaSeal II sealing films eliminate the need for heat-sealing devices or mats during thermal cycling.

Catalog Number: (490007-376)
Supplier: Excel Scientific
Description: ThermalSeal RT sealing films combine an optically transparent polyester sealing film with a strong, ultra-smooth, non-absorbing, non-fluorescing medical-grade adhesive for superior performance in real-time PCR applications.
