目前,R&D有多种抗体可供选择,包括针对各种细胞因子、趋化因子、蛋白酶、生长因子、粘附因子、神经营养因子、干细胞因子和发育蛋白的抗体,并且在不断更新。可以登录R&D网站获取最新抗体产品信息。

与很多公司不同,R&D抗体的97%以上为自产,严格的生产条件和QC保证了R&D抗体的质量,使得R&D抗体具备以下诸多优点:

 

l            BCIP/NBT

l            细胞因子    Cytokines

l            趋化因子    Chemokines

l            高质量 (Super Quality)

l            高特异性 (High Specificity)

l            低内毒素 (Low Endotoxin Level)

l            批次间的一致性 (High Lot-to-Lot Consistency)

l            高性能 (Superior Performance)

 

此外,R&D的抗体产品都无需也不含有叠氮钠(NaN3,剧毒)或其他保护剂,目前一般的抗体产品中都需加叠氮钠(NaN3,剧毒)保护,需要戴手套小心操作。

R&D的抗体用于以下多种实验:

l            BCIP/NBT

l            细胞因子    Cytokines

l            AP       (Affinity Purification)

l            B/N      (Blocking/Neutralize)

l            CD       (Cell Depletion)

l            ELISA(Cap) (ELISA Capture)

l            ELISA(Det) (ELISA Detection)

l            ELISA(Comp) (ELISA (Competitive))

l            FC       (Flow Cytometry)

l            FA       (Functional Assay)

l            EMSA    (Gel Shift)

l            IF       (Immunofluorescence)

l            IHC     (Immunohistochemistry)

l            IP       (Immunoprecipitation)

l            WB     (Western Blot)

 

 

Fluorokine Kit

Fluorokine在某种意义上是另一种形式的“抗体”。之所以这么说,是因为对于流式细胞检测而言,由于某些原因,一些细胞因子受体的抗体没有成熟的产品,为此,R&D推出Fluorokine产品,从另一个角度解决了这个问题。

Fluorokion是将细胞因子标记上生物素(biotin)、藻红蛋白(PE)等标记物,利用细胞因子和细胞因子受体的特异性结合(类似抗原抗体的特异性结合),检测标记的细胞因子数目,即可间接地测出细胞因子受体的情况。

 

 

Primary Antibodies

Quality Control
Each antibody is manufactured under controlled conditions, undergoing rigorous quality control testing to ensure lot-to-lot consistency and outstanding performance in a variety of applications.

Endotoxin Level
Neutralizing antibodies are tested to ensure low endotoxin levels which is reported on individual datasheets. The formulation of most antibodies does not contain azide or other preservative.

Formulation
For maximum stability, most antibodies are supplied lyophilized. This also facilitates easy shipping and storage.

Specificity
All antibodies are tested for cross-reactivity with related molecules by direct ELISA to ensure specificity.

Bulk Quantities
When experimental protocols require large quantities of a particular antibody, special bulk pack sizes can be purchased. This will reduce the cost per unit mass. Please contact us for a bulk order quote.

R&D Systems Antibody Types

Polyclonal

Polyclonal

Polyclonal antibodies offer multiple epitope recognition. Anti-sera and whole immunoglobulin (Ig) preparations contain a large amount of non-specific Ig, which could lead to non-specific antibody binding. Antigen column affinity chromatography eliminates non-specific IgG making these specific IgG preparations, in general, 10-fold more potent.

Monoclonal

MonoclonalMonoclonal antibodies offer monospecificity, recognizing a single epitope. All new R&D Systems’ monoclonal antibodies are derived from hybridoma culture supernatants rather than ascites fluid, and are purified using either protein A or protein G columns.

Labeled Antibodies

A range of both monoclonal and polyclonal antibodies are available conjugated to either biotin, fluorescein, allophycocyanin, or phycoerythrin (PE). Biotinylated antibodies eliminate the need for secondary antibodies and offer the flexibility to use any detection system for which streptavidin or avidin conjugates are available. Fluorochrome labeled antibodies are designed for flow cytometry detection and quantitation of intracellular or cell surface associated molecules. We also offer Peridinin Chlorophyll Protein Complex (PerCP)-conjugated antibodies for flow cytometry experiments. The spectral characteristics of PerCP make these antibodies especially useful for multi-color analysis with PE and fluorescein-conjugated antibodies.

Secondary Antibodies

Secondary antibodies are offered against goat, hamster, human, mouse, rabbit, rat, and sheep IgG, in addition to chicken IgY and are conjugated to a range of fluorochromes, biotin, or horseradish peroxidase to suit the needs of particular applications. Cell and Tissue Staining Kits to facilitate immunohistochemistry staining including secondary antibodies, blocking reagents, and detection chemistry are also available.

Species specificity of the secondary antibody is achieved by antigen affinity chromatography and/or cross-adsorption against IgG from non-related species to eliminate cross-reactivity. Fluorochrome labeled F(ab’)2 fragments eliminate non-specific interactions with Fc receptors expressed on certain tissue and cell types.
