robes associated with plant tissues also form biofilms (Mar-ques et al 2002 Dow et al 2003 Morris and Monier 2003 taining 2-5 mL of primary fixative [3% glutaraldehyde (Electron Microscopy Sciences USA) +1 6% paraformaldehyde (Electron Microscopy Sciences USA) in 0 1 M Na Cacodylate buffer pH = 7 5 (Electron Microscopy Sciences USA)] or enough to com-pletely cover all tissues

A general-use primary fixative would be 2% glutaraldehyde/2% paraformaldehyde in 0 1M cacodylate or other suitable buffer (PBS HEPES PIPES) Note: If precipitation is visible in final sections we recommend a buffer containing 2-Mercaptoethanol (0 1M Na Cacodylate 0 13M Sucrose 0 01M 2-Mercaptoethanol---see Common Buffers and Fixatives page) This can prevent osmium-based pepper

Tannic acid mixed with glutaraldehyde or paraformaldehyde is a strong fixative which can precipitate amino acids and oligopeptides such as arginine and glutathione Tissue specimens fixed with this tannin-aldehyde mixture are useful for histochemical studies including lectin labeling immunological staining and tissue enzyme digestion

Fixative Protocols and Recipes

Add 5 ml of glacial acetic acid just before use Wash fixed tissue in running tap water for 24 hours before dehydration Never use metal forceps or metal container when handling tissues fixed in Zenker Solution Note: Used for bloody specimens such as spleen as well as connective tissues Zinc Fixative

Tissues that have been fixed with a glutaraldehyde-based fixative must be treated or quenched with inert amine-containing molecules prior to the IHC staining because any free unsaturated aldehyde groups that are available will react covalently with amine-containing moieties such as antibodies (Schiff base formation) The most efficient aldehyde blockers/quenchers are ethanolamine and lysine

1 Fixation: Cut and fix plant tissues in fixative solution for 2 h then vacuum for 15 min without shaking If the tissues did not sink re-infiltrated for another 10 min The tissues can be stored at 4 C over night 2 Rinse: Rinse the entire samples in 0 5M NaPO 4 buffer and then wash tissues in 0 5 M NaPO 4 buffer for 3 times 15

It is well known that preparation of biological (plant and animal) tissues for Scanning Electron Microscopy (SEM) by chemical fixation and critical point drying results in shrinkage of tissues often by up to 20-30% depending on the tissue type and fixation protocol used We sought to identify a protocol that would preserve tissue size and morphology better than standard chemical fixatives

Some samples are prone to fixative-induced autofluorescence and this can be counteracted with reduction of the aldehyde groups with BH 4 or NH 3 Cl at 10 mM is more gentle reagent good for cells What are paraformaldehyde formaldehyde formalin? Glutaraldehyde preserves the cellular structure very well but causes strong autofluorescence and so is used mainly for EM Methanol Organic

Plant tissues typically consist of more than one cell type each with their own morphology and biochemical constituents Plant surfaces are therefore highly heterogeneous and the description of the optical response needs to take into account a complex distribution of refractive indices and absorption Moreover the shape and dimensions of epidermal cells (surface layer) strongly influence the

However glutaraldehyde alter the physical-chemical and mechanical properties of biological tissues The loss of hydrophilic properties and devitalizate cell xenotime provoke the formation of centers of dystrophic calcification The change in the viscoelastic properties of tissue xenograft under the influence of glutaraldehyde leads to deterioration in General microbiologica Bioprocess and the


tissues are referred to as 'phloem' the inner ones as 'xylem' Cultures were grown in a room maintained at 25 + IO C with dim diffuse light from a fluorescent tube for I2 hours a day Microscopical examination Tissues were fixed in a chrome fixative (Johansen I 95 I) or glutaraldehyde (Pickett-

The slow penetration may cause artifacts such us retractions 0 5 % to 3 % of glutaraldehyde combined with formaldehyde in isotonic buffered solutions is commonly used It can preserve the ultrastructure of tissues much better than other fixatives and that is why it is a preferred fixative for electron microscopy studies However it is not

Plastic (resin) embedding provides exclusively improvements to cellular definition compared to paraffin embedding The combination of strongly cross-linking paraformaldehyde with glutaraldehyde and post fixed with OsO4 is the fixative of choice for high-resolution light microscopy and electron microscopy For this reason this method is an ideal tool for visualizing plant cellular morphology

G 1365 (OTTO) Glutaraldehyde 25% Cas 111-30-8 - used in biochemistry applications as an amine-reactive homobifunctional crosslinker and fixative prior to SDS-PAGE staining or electron microscopy It kills cells quickly by crosslinking their proteins and is usually employed alone or mixed with formaldehyde as the first of two fixative processes to stabilize specimens such as bacteria plant

Mirsky's Fixative™ is a superior fixing agent for use in immunohistological and immunological protocols Mirsky's contains no formaldehyde or glutaraldehyde Therefore it has considerably reduced toxicity and virtually no odor Mirsky's Fixative is neutral buffered and isotonic (308 mOsmol) Additionally Mirsky's F

During in vitro maize plant regeneration somatic cells change their normal fate and undergo restructuring to generate pluripotent cells able to originate new plants Auxins are essential to achieve such plasticity Their physiological effects are mediated by auxin response factors (ARFs) that bind auxin responsive elements within gene promoters Small trans-acting (ta)-siRNAs originated from
