Tris has been useful as buffers in a wide variety of biological systems. Uses include pH control in vitro and in vivo for body fluids and in buffering systems for electrophoresis applications. Tris has been used as a starting material for polymers, oxazolones (with carboxylic acids) and oxazolidines (with aldehydes). Tris does not precipitate calcium salts and is of value in maintaining solubility of manganese salts. It can be used for the direct standardization of a strong acid solution; the equivalence point can be determined either potentiometrically or by use of a suitable indicator such as 3-(4-Dimethylamino-1-naphthylazo)-4-methoxybenzenesulfonic acid. It is an auxiliary material in pharmaceutical science.
Store at Room Temperature (15-30 °C). Store dessicated.

The CD28.2 antibody reacts with human CD28, a 44 kDa type I surface glycoprotein which acts as a co-stimulatory receptor in support of the T cell receptor (TCR). CD28 exists as a homodimer with specificity for two known ligands, known as B7-1 (CD80) and B7-2 (CD86), which are expressed on activated B cells and antigen-presenting cells. These ligands trigger CD28 signaling in concert with TCR activation to drive T cell proliferation, induce high-level expression of IL-2, impart resistance to apoptosis, and enhance T cell cytotoxicity. The interaction / co-stimulatory signaling between the B7 ligands and CD28 provides crucial communication between T cells and B cells or APCs to coordinate the adaptive immune response. Other members of the CD28 family of receptors include CTLA-4 (CD152), PD-1 (CD279), ICOS and BTLA.

The PolyStainer is used for staining sample material on slides. Usual staining methods include gram staining or May Grünwald staining. However, any other staining methods can be used in the 10 program slots available. Up to 20 slides can be processed as a set in a maximum of four staining solutions. The tanks for the staining solutions are interchangeable and are supplied with a cover. One reservoir has a volume of 450 ml. The periods of time during which the samples are to remain moving or resting in the staining solution, as well as the drip time over the tank, are freely programmable. The integrated water bath is used to rinse the samples. The rinsing time, and when fresh water is to be added, can also be programmed. The slides are dried in a hot air chamber located next to the water bath.

Protamine sulphate is a purified mixture of simple protein principles obtained from the sperm or testes of suitable species of fish, which has the property of neutralizing heparin. Because of having much basic amino acids (mostly arginine) protamine contains far greater nitrogen than other proteins. Its molecular weight is relatively small. Histone and other basic proteins in the testes of unmatured fishes convert into protamine along with the growth of the fishes. In the testes protamine takes the form of nucleoprotamine linked with DNA.

Storage: Room Temperature
Guanidine hydrochloride consists of a network of guanidinium cations and chloride anions linked by N–H•••Cl hydrogen bonds, it is a strong chaotropic agent. Guanidine HCl may agglomerate upon storage. It may appear as a free-flowing crystalline powder, a free flowing powder with solid material dispersed throughout, or a solid. The quality of the product does not appear to be affected and solutions prepared from the free-flowing and lumpy guanidine HCl appear identical.
Guanidine hydrochloride can be used as the first step in refolding proteins or enzymes into their active form. Urea and dithiothreitol (DTT) may also be necessary. Also used in the isolation of RNA. Guanidine hydrochloride is a strong chaotropic agent useful for the denaturation and subsequent refolding of protein, it can solubilize insoluble or denatured proteins such as inclusion bodies and be used for the recovery of periplasmic proteins.
