Phenotypic features were described from colonies growing on malt extract Agar (MEA). Malt extract 20 g/L, peptone 1 g/L, and D-glucose 20 g/L, Agar 20 g/L (HiMedia, Mumbai, India), OA (Sigma–Aldrich, St. Louis, MO, USA), and PCA (HiMedia, Mumbai, India) at 25 °C. Colony colours were assessed according to The Royal Horticultural Society London [16 ]. Micromorphological descriptions and measurements for 30 replicates of sexual structures and relevant features were carried out in lactic acid 90%. Photomicrographs were taken with a Keyence VHX-970F microscope (Neu-Isenburg, Germany) and a Nikon eclipse Ni compound microscope, using a DS-Fi3 (Nikon, Tokyo, Japan) and NIS-Elements imaging software v. 5.20.

Cell line -For in vitro cellular uptake and cytotoxicity, human cervical cancer cell line, MCF-7, and MDA-MB 231 were used. HeLa cells were obtained from Roswell Park Memorial Institute and which are cultured in RPMI-1640 and DMEM and supplemented with 4.5 g/L D-glucose, 1 mM sodium pyruvate, 1.5 g/L sodium bicarbonate, and 10% fetal calf serum (HiMedia Lab, Mumbai). The cells were maintained at 37°C and 5% CO 2 in a CO 2 incubator. MCF-7 and MDA-MB 231 were obtained from the National Centre for Cell Sciences, Pune and are grown in L-15 (Invitrogen, USA) supplemented with 10% fetal bovine serum (Invitrogen, USA), 100 units of penicillin/streptomycin (Invitrogen, USA) at 37°C and 5% CO 2 in a CO 2 incubator.

Check if the same lab product or an alternative is used in the 5 most similar protocols
All strains and derivatives used in this study are listed in Table 1. Lactococcal strains were grown in M17 medium (Merck GmbH, Darmstadt, Germany) supplemented with D-glucose (HiMedia Laboratories, Mumbai, India) (0.5 % w/v) (GM17) at 30 • C. Escherichia coli DH5α was grown aerobically in Luria-Bertani (LB) broth (HiMedia Laboratories, Mumbai, India) at 37 • C. Solid medium was made by adding 1.75 % (w/ v) agar (Torlak, Belgrade, Serbia), to the liquid media. Antibiotics were used at the following concentrations: Erythromycin (SERVA Electrophoresis GmbH, Heidelberg, Germany) was used at 300 μg/mL for E. coli and 10 μg/mL for lactococci for selection and maintaining of transformants. Spectinomycin (Merck KGaA, Darmstadt, Germany) was used at 250 and 500 μg/mL for maintaining of invertants and 50, 100, 150, 200, 250, 300, 350, 400 and 500 μg/mL for determination of MIC values for Spectinomycin of transformants in lactococci. For blue/white colour screening, 5-bromo-4-chloro-3-indolyl-β-D-galacto-pyranoside (X-Gal) (Fermentas, Vilnius, Lithuania) was added to LB medium plates of colonies with cloned fragments at a final concentration of 40 μg/mL.

Biosensing of Biomolecules Using TE-Derived Nanoparticles

Check if the same lab product or an alternative is used in the 5 most similar protocols
TE was collected from the botanical garden of the BHU campus, Varanasi, India. Other chemical reagents were procured from Sigma Aldrich. For the dilution of the reagents required during synthesis, DI water was used. All the sensing measurements were done with DI water. The metal salts l-cysteine, d-glucose, glycine, creatinine, ascorbic acid, uric acid, and Tris HCl buffer were purchased from HiMedia, Merck, and Sigma Aldrich. Different kinds of metal salts were also prepared in DI water for optical sensing. For the real sample sensing, HBS samples were collected from Prakash Pathology, Varanasi, India.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
