The 96 properly plates is one kind of ELISA PLATE, is a key position within the Enzyme Linked Immunosorbent Assay (ELISA). It’s concerned within the immunological response, similar to: antibody or antigen coating, buffer block, and so on.

The properly plate is manufactured in a GMP clear room. The product quality is strictly managed in accordance with the necessities of ISO and ANSI/SLAS Requirements to make sure the soundness of the product batches. The product variation coefficient of every plate gap and batch is lower than 5%. The product adopts optimized floor remedy know-how, which successfully improves the adsorption capability of the protein within the excessive and medium binding capability ELISA plate, and improves the sensitivity of the product to protein adsorption detection. It may be broadly utilized in varied kinds of ELISA, PCR detection, Cell tradition, scientific analysis, and so on.

In accordance with the microplate reader, it’s divided into removable and non-detachable.

For the non-detachable, the properly strips on an entire board are linked collectively.

Then the removable is that the properly strips on the board are separated, and the separated strips are 8 wells or 12 wells per strip.

Typically, removable microplates are generally used. Though all properly plats has similar apperance, however totally different manufacturers have their very own technical distinction, similar to construction, protein adsorption efficiency, and so on. Whilst you select to purchase 96 properly plates, you must also take into account which model of microplate reader is best you.

In accordance with the totally different binding means with protein and different molecules, the ELISA plate may be divided into the next classes:

After floor remedy, the protein binding capability of the ELISA plate is enormously elevated, reaching 300–400 ng 1gG/cm2, and the molecular weight of the primary binding protein is >10kD. To make use of one of these properly plates can enhance the sensitivity, and might comparatively scale back the focus and dosage of the coating protein. The drawback is that it’s simpler to supply non-specific reactions. After the antigen or antibody is coated, non-ionic detergents can not successfully seal the unbound protein websites, and protein must be used as a sealant.

The ELISA plate is passively mixed with white by means of the hydrophobic bond on the floor, and is appropriate as a solid-phase provider for macromolecular proteins with a molecular weight of 20D. Its protein binding capability is 200–300 ng 1gG/cm2. Because of the attribute of ELISA plate that solely binds to macromolecules, it’s appropriate as a solid-phase provider for unpurified antibodies or antigens, and might scale back potential non-specific cross-reactions. This microplate can be utilized as a blocking answer with inert protein or non-ionic detergent.

After floor modification, the alcohol commonplace has a positively charged amino group, and its hydrophobic bond is changed by a water-killing bond. It’s appropriate as a strong section provider for small molecule proteins. Utilizing an acceptable buffer and pH worth, the floor can bind to small negatively charged molecules by means of ionic bonds. Because of the hydrophilic properties of the floor and the power to covalently bond with different crosslinking brokers, it may be used to immobilize protein molecules soluble in detergents similar to Triton-100 and Tween20. Its drawback is that as a result of lowered hydrophobicity, some protein molecules can not bind; as well as, its floor must be successfully sealed. Because of the hydrophilic and covalent floor traits, the sealing fluid used should be capable of work together with the non-reactive amino teams and any useful teams within the chosen crosslinking agent.

A protein answer of recognized focus can be utilized for coating on a clean properly plate for ELISA. Measure the protein focus of the answer within the properly after coating. The quantity of protein within the properly earlier than coating minus the quantity of protein after coating is the quantity of protein adsorbed on the plate. On this manner, we are able to know the adsorptivity of the microplate.

There are 4 sorts supplies: Polystyrene, PVC, Poly-D-Lysine and Quartz. Polystyrene is often used to make 96-well plates, however polystyrene has poor chemical stability and may be dissolved by a wide range of natural solvents (similar to fragrant hydrocarbons, halogenated hydrocarbons, and so on.), and will likely be corroded by sturdy acids, alkalis and anti-grease. simple to alter coloration after being irradiated by ultraviolet gentle, so watch out throughout use.

Wells: 96 wells

properly is essentially the most generally used now, as a result of the microplate is used with microplate reader.

Struture: Removable and non-detachable (SOLID)

Colours: Clear, White, Black


  • F-Botton (mostly used);
  • U-Botton (for good mixing),
  • V-Botton (for microtiter use),
  • C-Botton (flat heart with rounded corners to enhance fluid restoration)

The Board (3 colours: clear, white, black)

Properly Strip (3 colours: clear, white, black)

8 properly breakable strip and 12 properly breakable strip

The Lid

  • Properly Plate diameter: 6.8mm;
  • 96 properly quantity: 360 μL;
  • Working quantity: 75–250 μL;
  • Max. quantity: 24,000 μL per properly plate

In accordance with the ANSI/SLAS-Requirements 1 to 4–2004, the usual 96 properly plates dimension are 127.76mm(L) x 85.48mm(W). It’s internationally acknowledged requirements, contains 5 requirements as beneath:

ANSI SLAS 1–2004 (R2012): Footprint DimensionsANSI SLAS 2–2004 (R2012): Top DimensionsANSI SLAS 3–2004 (R2012): Backside Exterior Flange DimensionsANSI SLAS 4–2004 (R2012): Properly PositionsANSI SLAS 6–2012: Properly Backside Elevation

1. The solid-phase polystyrene floor as a provider additionally performs an necessary position within the adsorption of antigens, antibodies or antigen-antibody complexes.


2. Antigens, antibodies and different biomolecules are adsorbed to the floor of the provider by means of a wide range of mechanisms, together with passive adsorption by means of hydrophobic bonds, water/ionic bonds, covalent bonding by means of the introduction of different lively teams similar to amino and carbon teams, and thru Hydrophilic bonding after floor modification.

Utilized in varied experimental platforms: IVD reagents, Lateral Circulation Assay, ELISA, PCR, nucleic acid detection, DNA extraction, cell tradition, scientific analysis, and so on.

It’s broadly utilized in meals contamination with ELISA take a look at, PCR take a look at and Lateral Circulation Take a look at. The 96 properly plates common utilized in milk take a look at package in uncooked milk detection antibiotic residues. In contrast to the standard lateral circulate design, the labled Colloidal Gold is not going to dispens on the nitrocellulose membrane, it’s separated from strip, load on the 96 properly plates assist enhance sensitivity, quick dilute analyte and shorten the detection time.


Properly plates is a generally laboratory consumables, aside from 96 properly plates, there are some kinds of microplates: 6 properly plates, 12 properly plates, 24 properly plates, 48 properly plates, 96 properly plates, 384 properly plates, 1536 properly plates.
