| ln Vitro |
When compared to responders who are not treated, streptavidin (2-200 μg/mL) greatly inhibits the proliferation of Lewis T cells to WF by 76%–83%[1].
|
|---|---|
| ln Vivo |
In the high-responder WF-to-Lewis combination, streptavidin (8-80 mg/kg) therapy is beneficial in extending rat cardiac allografts[2].

| Cell Assay |
Cell Viability Assay[1]
Cell Types: Lewis T cells Tested Concentrations: 2-200 μg/mL Incubation Duration: Experimental Results: Inhibited the proliferation of Lewis T cells to WF stimulators by 76%-83% compared with untreated responders, lower concentrations of 0.1 and 0.2 μg/mL did not Dramatically inhibit T-cell proliferation. |
| Animal Protocol |
Animal/Disease Models: Lewis rats[2]
Doses: 8, 12, 20, 40, 60, or 80 mg/kg Route of Administration: Administered IP for 5 days after transplantation was combined with a single dose of 0.5 mL antilymphocyte serum (ALS) on day 0 Experimental Results: Prolonged cardiac allograft survival from MST of 7.3±0.5 and 8.4±0.5 days in naive and ALS-treated controls, respectively, to 15±1, 20±3, 16±3, 17±3, and 23±2 days, respectively. |

| Additional Infomation |
Streptavidin is an organochlorine compound.
A 60-kDa extracellular protein of Streptomyces avidinii with four high-affinity biotin binding sites. Unlike AVIDIN, streptavidin has a near neutral isoelectric point and is free of carbohydrate side chains. |

Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
Injection Formulations
Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).

Injection Formulation 4: DMSO : 20% SBE-β-CD in saline = 10 : 90 [i.e. 100 μL DMSO → 900 μL (20% SBE-β-CD in saline)] Oral Formulations
Oral Formulation 1: Suspend in 0.5% CMC Na (carboxymethylcellulose sodium) Oral Formulation 2: Suspend in 0.5% Carboxymethyl cellulose Example: Take the Oral Formulation 1 (Suspend in 0.5% CMC Na) as an example, if 100 mL of 2.5 mg/mL working solution is to be prepared, you can first prepare 0.5% CMC Na solution by measuring 0.5 g CMC Na and dissolve it in 100 mL ddH2O to obtain a clear solution; then add 250 mg of the product to 100 mL 0.5% CMC Na solution, to make the suspension solution (2.5 mg/mL, ready for use in animals).

Oral Formulation 3: Dissolved in PEG400 (Please use freshly prepared in vivo formulations for optimal results.) |
| Preparing Stock Solutions | 1 mg | 5 mg | 10 mg | |
| 1 mM | 2.6405 mL | 13.2027 mL | 26.4054 mL | |
| 5 mM | 0.5281 mL | 2.6405 mL | 5.2811 mL | |
| 10 mM | 0.2641 mL | 1.3203 mL | 2.6405 mL |
*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
